That was a great video! Sometimes it's assumed that everyone knows how these rudimentary components work, but that's not always the case. It's good to see someone occasionally take the time and effort to explain their operation. I could watch this kind of stuff for hours! 😁
For HVAC service, there are valve core removal tools that remove a significant restriction when pulling a vacuum. Also useful when you need to replace a leaky core while the system is still under pressure.
Also seen them on old hard drives, where they were used to fill the purge gas into the drive, typically ultra dry nitrogen, so that the hermetically sealed drive was slightly pressurised with gas for it's entire operating lifetime, so no moisture got in to corrode the uncoated magnetic media on the platters.
Good old car tyre valves as we call em in the UK. I used to work for both Sturmy Archer and Raleigh (The latter, still trading next to my mates place in Eastwood, Nottingham, who made their name in bicycles), which this type of valve was in common use, along side the Woods (Was secured by a screw type collar, though not as common as it once was, though on bikes, this is my preferred valve), and Presta (Mostly found on racing bikes, where the use of a Schrader would be too big..... hate dealing with this type of bike valve).
Question for you Got 1 on my Chevy that's caroded in place how to replace a stuck shrader with out messing up with the TPM and makeing an already big mess worse Thank you In advance
Are you able to pull a vacuum with a standard bicycle or car style schrader valve simply by connecting a chuck style filler and connecting to a vacuum pump?
The tractor valve stem is probably designed for high flow. I don't think it has deal with the pressure and heat a car or truck does either. I looked up the pressure ratings of Schrader valves one time. With the right stem, good for 5000 psi.
Hey Ed, would you happen to have any idea on what happened to Photon? (Andy) he hasn't posted anything new for nearly a year, and I can't find anything about him...
Smashing, very enjoyable video Ed :-D. I always suspected the ones in fridge systems had to be different in seal type or build quality, but i don't know anyone that's tinkered with them to ask. I would imagine the older long spring type would need a slightly smaller hole near the innertube so the brass cup won't go through, so the spring is compressed. If the valve stem is made modern the old long spring ones won't work :-(
I used to sort of work at a tire place and those valve pin things were everywhere on the floor in the shop. I took a bunch of them home and I have them somewhere. They are sometimes replaced when the tires are changed. The entire rubber valve stem assembly sometimes depending on condition. I guess throwing them in the garbage is too much effort.
any decent tyre shop will cut the old valve stem straight off and replace the lot with the new tyre, not worth a single customer ever coming back with a leaking valve when the things cost a few cents ;) especially when the average motorist will not even notice a leaking valve until the rim is on the ground raping that tyre, and then the tyre shop is up for a $100+ tyre under warranty all over saving a few cents, it's all built into the cost of fitting and balancing anyway (or the tyre price if the shop doesn't charge seperately for fitting and balancing) most people who have been doing it for a while don't even unscrew the old valve to release the air, just grab the stem with the weight pliers and rip it in half :D air releases quicker through the larger hole and you can break the bead basically instantly. Even the valve caps are replaced because once again it is not worth a single customer coming back with a valve leaking ever, if that tyre comes back with a leak and it's not a puncture somebody is getting their arse kicked :D PLUS the old valve caps make great projectiles for the mechanics to shoot at each other, not as good as chunks of HT lead, but they both fire out of plug boots very nicely :P
yeh my first RAV4 had new-ish tires but old stems, 2 of them split at the base when I went to put air in the tires. the cores, if all brass, can be collected and sold as brass scrap around here for $4.80 a Kg, same with tubeless valve stem scrap if you burn the rubber off them,
Possible, its just odd given tractor tires often have water in them to lower the center of gravity and prevent rollover, Brass or Stainless would make more sense.
The only reason I'm even watching this video is can I put slime through a bike tire trader valve if somebody get it quickly answer that I would be very delighted to know whether I'm fucked or not any info would be appreciated thank you
Is it an Australian sign of affection to call a child relative a "poppit"? i heard it on the wild Thornberry`s but the dad Nigel ..i think was from England ive also heard it used in a DIEANTWOOD video from South Africa ,Australian/south African accent sound similar.
No mate it ain't Australian term...well maybe, if a kid has acne..... squeeeeeze..........POP!!! Oh, that was good... 'Hey "POPIT", come back here, there's another one on your forehead....

Great to see you making vids again Aussie :)
The schrader valve is truly one of most important inventions in recent history.

It makes me really happy to see more regular uploads from you, mate! I always enjoy the content!
always happy to see something new from Ed Systems
This was very good, thanks. I never even knew that valves could be removed.
Just goes to show, if it ain't broke, don't fix it, that and the KISS principle too... :)

Oh yeha I have seen them on industrial equipment including my Saber Jet radar magnetron unit, for Nitrogen filling
Every 3.5" and smaller drive I have taken apart just used foil stickers as seals.
great valve they are, i have pushed them up to some pretty high pressures too.
Bugging me.... Is that a 30-06 M1 Loading clip in the background?
enlishbob Thought that too. Cool!

I've pulled out red and black banded valve cores from tires. I,ve always wondered what the difference was, if there was any.
should i tighten these on my car ac a bit? whenever i take protective cap off i hear small hiss
Mate, you have more ammo lying around than me. More power to you!
Question for you
Got 1 on my Chevy that's caroded in place how to replace a stuck shrader with out messing up with the TPM and makeing an already big mess worse
Thank you
In advance
what is the name of adaptor of a tire pump which connect to car tire schrader valve ? how it works ?
These get used in some flue injector rail systems for vacuuming the air out.
Also correct, my Ford Escape had that!
Gotta love the Scrader valve
Are you able to pull a vacuum with a standard bicycle or car style schrader valve simply by connecting a chuck style filler and connecting to a vacuum pump?
I also see them in small propane, oxygen, and MAPP gas cylinders, good old design!
I've seen green ones, might've been from vehicle AC rail, not sure.
yeh absolutely, my Bernzomatic has them, very universal valve, they just change the seal material depending on gas type and operating pressure/temp.
nice explanation aussie50. what is refrigeration fluid?
Pretty informative video. XD
Schrader vavles in tires and the AC system appear to have different sizes, do they have the same sized core?
The tractor valve stem is probably designed for high flow. I don't think it has deal with the pressure and heat a car or truck does either. I looked up the pressure ratings of Schrader valves one time. With the right stem, good for 5000 psi.
Only the pin was removable, the core part with seal , I could not replace it....luckily I had a high quality metal cap with seal inside

I feel like I’m watching an AVE video keep it up

You sound like Dean from the curiosity show... Thats not a bad thing in any way.
lol yea its truly amazing how these tiny things actualy what supports the weight of machines, vehicles etc, if it pops you be riding real low
I have one of those on my body and I always wondered what it was.
"anti-fatigue ration is now 3 milligrams"
My car has what looks like a schrader valve on the fuel (petrol) injector rail too, presumably for bleeding air out.
it's for testing fuel pressure
The tractor valve core is aluminium and smaller possibly due to being a much larger tyre, it requires much less air pressure.
Possible, its just odd given tractor tires often have water in them to lower the center of gravity and prevent rollover, Brass or Stainless would make more sense.
My high pressure A.C port is leaking.
What about "Presta" valves.
The only reason I'm even watching this video is can I put slime through a bike tire trader valve if somebody get it quickly answer that I would be very delighted to know whether I'm fucked or not any info would be appreciated thank you
Yay he said "Aluminium"
Might have helped to have the video microscope for closeups of the valve components. Still was interesting to see.
yeh I was almost going to scrap the video, but I cant be buggered re-shooting it for the 3rd time :p
Aussie50 Know that one, re-shooting vidjayos is a pain in the ass. :D

Look up Umshini Wam by DIEANTWOORD by the way i loved your comment
haha no, its a Pommie term ;P
Adorable
Watch out for the French and their weird Presta valve.
oh those things :P I have never had a racing bike so I have never had to use one.
