For some reason i was the only person to report these a-holes selling a product that they know is dangerous.I have emails with them and they keep telling me it is normal and expected for the black cylinder to shoot out of the gun, breaking the outside body, if the co2 is left in the gun at all. But they said if i pay to send it to them they would take a look and tell me how much they would charge to fix it. Now that is great customer service. I hope some others file some incident reports to the consumer product safety administration. Knowingly trying to injure people with faulty products is crap.
And thank you for this video and others. I wasn't having much success reassembling the valve. This should help
ya many guys from my group reported them and showed videos of them and some blood of coarse, they just blame us for modding its ridiculous and sad, they also blame the ammo we use as well its a joke lol
What size are those screws?
I called Umarex in Germany and was told that customers have only had the pressure chamber come loose when it was left pressurized overnight. Unfortunately I can't verify this, but fortunately mine has lasted to this day without modification. I also have an HPA system with 1100 psi connected and so far no problems despite the generation 3.
I didn't have any luck getting 3mm set screws so I used 4mmx.7 and only drilled out the two crimped spots instead of four. I used Red Loctite. Worked great. I thought it was a done deal when that thing burst out of there on me. Thank you. It now works excellent. I was hesitant about popping the CO2 seal but when I did it was silent. The little pin sticking out the back was confirmation.
So mine leaked the second time I used it after this repair that wasn't exactly as this video says to do it. So perhaps being patient and obtaining the proper items might work better. I had no luck finding 3mm so I used 4mm and I only drilled the dimples from the factory crimps as I was leery of fucking up two more holes without some sort of way to keep my drill bit true. I feel that when I went to change out the cartridge that the unreasonable amount of torque required to free the cap also breached my new loctite seal just as it twisted the crimps right through all the threads in the first place. Ultimately it is engineering design failure by umarex. Sucks because this thing was a lot of fun the two times I was able to play with it. Luckily I would never be so dumb as to rely on this for self or home defense.
just get the new threaded crimped valves, problem solved, guys are using 1500 psi in the and breaking through cinder blocks in the group
So, as far as I can understand, a 12 gram cylinder has what PSI? 800 approx.? This type of valve crimping does not support 1300 con HPA
I have a valve crimping but I only use 12 grams, there should be no problem for a PSI of 12 gram cylinder
Look at one thing and you will see why I say this, in most air guns with co2 the cylinders are introduced with the neck upwards and we put the cap in. What do we hear while we press? A sound of air and we press more and more until the sound stops, in the case of the umarex they are designed to be punctured when needed as when putting the threads and we press we do not know if it is well adjusted if it is not the bottle will puncture yes but there may be a small leak that we do not notice because the cylinder goes in that tube. If there is a leak and we decorate the shots the accumulation of gas will be greater
Nice mod. Good idea 👍. So you drill all the way into the CO2 tube... Hope it wont leak 🙏. Good luck my friend 👍
thanks bro, yes this one i drilled all the way through and i di and hdr 68 and did not go all the way through, test coming soon for them :)
@@UmarexLessLethalHomeDefense Looking forward to the testing bro 👍
Thank you for your informative videos. If you don't know Complete Technology Solutions supposedly is selling the new valve that is threaded. I believe he is an umarex dealer.
yes i bought a few from him thank you :)
You could also use some j.b weld or liquid nails. Or you could a dye and reverse dye to thread the valve.
ya theres a few things out there, im gonna test soon
I had mine explode and I did no modification on my 11 joules I think it's factory fault. The markers are brilliant but Umarex needs to correct this issue.
bro as a mediocre airgun engineer lol , i myself would rather use some tiny stainless steel bolts or machine screws ,some with a lot of fine threads and with a small head on it . because of the nature of what you are working with , the metal can expand past the grub or set screws and still come of , let us know later if still holding up . i bought all the great hpa stuff HOME DEFENCE -24 sells but in the last 8 months i have just been using 12 gram co2 because the many ones i mod are for carry . i guess when i start modding them for double the 42 joules i get now , ill do something about this . i just told RUNE the other day ,im looking into welding,brazing or soldering ??? all in all i always enjoy your vids my brother !!!
ya bro, the guy who showed me has done it to 2 valves and it holding so far for him, ill keep every one posted, but im only using 1100 psi max and i got 4 grub screws installed, the m17 pvr delete you can do the same thing, i think the 4 screws going through the metal will be enough for 850 to 1100 no probs but time will tell :) thanks bro :) and th braising will work with the alloy but im not sure about metal to alloy, unless there is some rods you can buy for that purpose
@@UmarexLessLethalHomeDefense how about the aluminium alloy type quick welding rods you get online ? anyways , i will wait to see your results my brother . i trust you 100% my brother !
You’re getting 42 joules out of what? With co2?
@@tnpyro5081 home defense 24 firing pin ,2 piece tuning barrel with sniper extension , internals fitted and polished , generous amount of silicone oil , eazy peazzzy !!! is that really so f-ing hard to believe ??? oh YEAH !!! 12 co2 only , its easier to carry it better without having to lug around hpa tanks ,hoses ,fittings , air compressors etc. LOL !!! my goal is to only get just 6 shots per fill , any Questions ???
I just bought the power kit & the valve is a tad loose, the seller has sold lots of them& told me silicon sealant will hold it in, I have the 7.5 j version
LOL! I found out they did this simply to increase profits, it takes more energy to thread them at the factory I guess. A bit less absurd than the theory they made the tube less safe on purpose... As I don't have any pematex 592 sealant, I am wondering, what if I just put baking soda and superglue around the rim... My hypothesis is that in order to "explode", the tube needs to expand the crimped rim so that it can release. But if there is a solid object around the rim, then it cannot expand, because of the aluminum container around it, and thus stays stationary.
The risk of those valves is for PSI 1300 ?
u r awesome brother !!
i appreciate u sincerely.
thank u for making this video.!. i saved it in my files. Awesome instructionals!. God bless ya from Northern California! 🥳 🎉 🪅 🎊 🙏 🌞
I hope will be ok now the valve
thank you for your kind words bro :)
@@UmarexLessLethalHomeDefense ❤️
Let's see, this is to reinforce the valve body because it seems that in some cases it is crimped. and others screwed together which let's say is safer, I think that part of the plastic tube is only designed to house the cylinder in theory I don't think it needs to be so reinforced why do I say this? Why can the tube that goes to the valve explode? I think that this is caused by an increase in gas inside that tube and that causes a gas leak from the cylinder. The cylinder is punctured if during the time that the valve is punctured the valve does not close and open correctly releasing the gas that it needs to charge the power of the valve we can have an accumulation of gas inside the tube where the cylinder is and this can cause an accident because the explosion of the gas does not come outwards it does so inside at the same time that it is fired. My approach is when we close the cap where the bottle goes, we must tighten it enough until we feel it hard. If we do that, we ensure that the bottle does not have any play. By painting it in this way we ensure that there is no leak and that there is no accumulation of gas inside the handle. I think that the problem is not in the valve parts, but in what causes this explosion.
Are those screw tips preventing a 12 gram cartridge from fitting in the tube if left that long?
Thank you for the video! 🙏
not at all, the screws are up past where thr restrictor sits but not drilled all the way through so there no issues, i dont that to my new valve, we dont need to drill all the way through
I have emailed Umarex asking which valve my HDR50 has off the serial number provided to them, surprisingly no replies back as yet. Guess I will have to strip it down to find out.
ya there being ignorant about these but sooner or later there gonna have a shit load coming back lol
Bruh this is garbage soon as I go to buy hdr umarex pulls this shit man thats alot to go through just to get the damn valve back to where you can modify the thing smh @ umarex but I guess it's possible to still find uncrimped valves but price probably going to crazy but the danger factor is like wtf im trying to use it as self defense not to kill my damn self with because the valve fails they continue to do this i think their going to loose alot of business why not just let it be you loose your warranty if you modify but I guess thats not enough but I damn sure wont own marker with crimped valve that sad because their markers had so much potential i couldn't imagine getting hit by sharp .68 cal zram at over 90j id say that is lethal but they advertise it for self defense but the joules they limit their so called ltl weapons wouldn't stop nobody you demonstrated that but its matter of time before they get class action lawsuit for crimped valves they will think twice then if they sold them with appropriate joules for self defense we wouldn't be modifying the damn marker in first place oh well your content is amazing brother keep it coming!!
ya man its bull shit, i just dont get why umarex would pull this shit its beyond me man its fing sad
@Umarex T4E Less Lethal Home Defense it is man I would say it's because markers can easily be made lethal by someone with your know how but they still wouldn't be held responsible in such case it would fall on the person that modified the marker but that should be our decision to make your markers especially those zrams would no doubt be nighty night time but like you said in one of your videos if you're protecting your family you can't rely on even 20 joules I don't feel safe but their going to get a family slaughtered by marketing them as home defense weapons out of the box hopefully everyone does their research before seeing oh its .50 caliber surely it will do the job and yeah they will more than do the job with modification. I hope that valve is still holding strong you got a fix for everything brother why is everybody else failing to reach even 35j with hdr50 and the valve block removed what did you do different they didn't or am I missing something so you remove the valve block and restrictor disc I know I'll need longer barrel to get into higher joules but I gotta be missing something brother
oh dam and i dont know witch one i have would be real easy to tell if i dident have to take off the peace of metal all the springs are under safe bet is gen 3 though since i got mine (stock tr50 7.5) about a month ago i thought at worst i was going to have to replace an o-ring i hope my valve dosent blow off would be nice if we could just reverse thread the two peaces that connect at the valve so your screwing it tighter everytime you tighten the co2 screw at the bottom but i dont have much in the way of tools i do have a little makita drill though i might try this if i feel brave enough to remove the metal peace or i cant get the valve block out without tapping it out im just waiting for my barrel kit from mcs to come in before i take it out (home defence is sold out and was more exspensive on z ram site) but probably just going to order an 11 joule gen 1 or 2 valve if i can and put that in instead.
rockstar tactical has the new threaded valves so your best just buying one for 30 us, this method is hit or miss
@@UmarexLessLethalHomeDefense ill see if i can get one and when i open the metal housing ill replace the o ring at the same time with some ones from z ram and maybe the power pin too just for the heck of it im going to be getting the z ram extension mostly going to be running co2 but i will be using hpa sometimes specially in winter like it is now if i open and see that my valve is threaded though ill be happy i wont have to order one my marker is only a month old but could be overstock ill be finding out soon enough though i think i just want to get some other parts in the mail first before i open it again
Planing to just used my spare 11 joules valve but how can i remove the co2 restrictor disk?
i have vids that will show you just have a look :)
totally awesome
I need to know something... There is a grease... inside these markers. Some people believe its silicone oil, but its not silicone oil... it is a black grease... maybe lithium grease... I need to know what type of grease this is... my theory is you need to add more grease every time you take apart these markers, to extend the longevity and performance of these markers...
yes i dont use it i wipe down all the parts and use ultrasilk
@@UmarexLessLethalHomeDefense Ty
my gun, the Co2 reservoir released after the gas was activated, a loud burst and at the time I hurt my wrist, I think it is a dangerous project, as it is clipped and coated internally with some adhesive material, good when we talk about pressure, the correct thing would be parts with threads .
i have tested this extensively with 1100 psi hpa and its not going any where :)
Thank you for your effort and time to help others out. Geat video.What size bits do i use to drill out
i used m2 but m2 will work
the co2 black cylinder of my 11 joules fell out when removing the cap. i dont know if i screwd it too tight? but now i dont know how to fix it.
Another issue with the exploding is people leaving the CO2 pierced for days at a time. Once it's pierced it should be emptied either with shots or unscrewed to release the remaining air. I believe that's why Umarex gives it's customers so many rubber balls for practice so you don't have to use up your good ammo. A good weapon but very sensitive. I choose not to carry this one,, home only...
yes i dont play with co2 for defense i use 1100 psi hpa and around 50-60 joules at least
Let's see, you are mostly right, the screw-on valve has a better hold than a pressure valve, but this problem is caused by the loss of gas when there is a gas leak, whether due to a fault, this can cause the cylinder to be punctured and empty it hours later, this maintained pressure damages the valve needles and can end up leaking gas with each shot, these valves also do not allow pressure of 1200 PSI maximum, 800 is what they are designed for.
@UmarexLessLethalHomeDefense So you acknowledge that a valve encrusted is not suitable for 1100 PSI
@@Alfonso-s2n I'm talking about 12 gram CO2.
@@montizzlefoshizzle7131 I know you're talking about Co2 12 gram payrolls
Great Vid. What sixe grub screws are you using?
m3
Give us the drill size and screw dimensions, please
im using m3 set screws and i think 2.5mm drill
I have a simpler solution.
On my hdr 50 I disassembled the valve and wrapped adhesive rubber tape around the co2 receptacle tube, so that it fills the empty spaces inside the armature, so whenever you tighten the co2 cap the rubber mold prevents the valve from becoming loose or move to prevent damage, and if the co2 tube ever comes loose, it will never be released, as the inner rubber mold forces it to remain in place.
How strong is the adhesive? How many lbs. will it hold?
anyone have any advise for repairing the seal above the crimp when thats blown? This was on an unmodded 7j valve! The seal has just bulged out from one side and now it leaks through it. Umarex seem to have a real problem with their manufacturing and quality control with this part from what I'm reading.
rockstar tactical has the new threaded valves they are also crimped now
It almost killed someone I know. It's crap and they should be hold accountable. Let us know if the Mod is still holding up
yes its still going good so far, i have a new threaded valve incase it happens
Is it still at risk of blowing off using the hpa buttstock attachment for the hdb from hd24?
yes i think its always a risk on the valves, but its better to go through that way then the co2 tube
@@UmarexLessLethalHomeDefense thank you for the response! I just JB welded everything following your instructions and so far so good. 83J with 1100 psi and jul v2s. Do you have any tips for stopping it from jamming? It Seems to be over feeding issue.
Hey Buddy, can you please tell me what year and month that Umarex started to do this to
the HDR68 and how do you know which Generation each gun is ???
look at the valve and see if its crimped or not,
the crimped valves are gen 3 and the ones with 2 dimples are gen 2 or 1, the gen 2s have a plastic cap on the pin and the gen 1s have a red oring on the tip of the pin
Probably a dumb question, but what pin is that on?
Thanks, ima have to to this. I herd leakig as soon as i hit the punch button and then BAM! I took the valve right to the chin. The damned thing flew up too. Guess it was a good thing it stated leaking a bit first. LOL. Then i thought of drilling and i put rivets in. Well, that didn't last long and almost hit my cat. It didt leak with the sealant i used though, but guess the pressure just bent the rivets til it gave. So, I am trying this and hope it works. My neighbor wants me to mod his with an HPA tank, so b4 I do that I'll see how ur update goes. Thanks.
so far its holding up to 1100 psi in many tests so this one aint popping off at all i made a few vids shooting it on a hdr68 valve i tapped with set screws
Just so I understand, you're saying you had a valve blow off and it hit you in the chin? Did it go all the way though your skull or did it get caught inside it. Matter of fact if you have a video of it happening I'm sure it will go viral. You might want to think about setting it up so you can have it on video I'm sure it will launch you into being the next RUclips influencer. Well you be launched at least.
What an absolute joke that such low quality engineering is part of the mainstream marketplace. Late stage capitalism I guess.
Is that m3 x 0.5
i think m3x1
Yes, ISO - DIN 13-1 (EU)
It's pretty weird that they would risk losing money and customers over this. It's not like they can be held responsible for our mods... unless I'm missing something.
and why don't they just offer suoped up versions like what people are modding them to, for an extra 100$? like they have the 40j hdx.
@@airgunsanonymouslesslethal1904 this issue is not cause by any mods at all, its the crimp is failing cuz torquing on the co2 piercing cap back and forth and cranking it with an allen key is weakening the crimp, these are blowing off markers with just 12 gram co2 unmodified, the gen 1 and 2 threaded valves dont do this ever, its sad umarex has went and done this just so we cant mod them its very sad and disgusting knowing some one can get hurt or worse
Nice job. Sometimes you can find a 6 or 12 point socket will grab the square drive of the tap well.
@@UmarexLessLethalHomeDefense i understand all of that my friend. It was all in your video that i just watched. I think you miss understood my comment.

yes its very day that umarex done this to us, i heard they are going back to the threaded ones for next year some one announced in my facebook group

we cant use firearms here for defense
@@UmarexLessLethalHomeDefense Oh I was referring to an airgun not a firearm, I was just pointing out the irony of someone buying a gun for protection and getting injured by the gun they bought for protection. Did canada completely ban firearms, I thought some firearms were still allowed, but not for defense?
