How to put slime in a presta valve tube (non-removable valve core)

- How to add slime to a 29er tube with a presta valve. Note that the valve does not have a removable core. Valves with removable cores would be removed by un-threading the valve body instead of the core.
Update 5-18-17: I rarely use slime in tubes, in fact almost all of my bikes are converted to tubeless with stan's sealant or truckerco cream, both of which can be used in tubes as well with better results than slime.

9 years later and still a useful video. Dropped the core in the 4" tube. Took a while to find it, but in the end it all worked. Thanks!
i'm so going to drop the core, i just know it :}
Brilliant - well done! Can't get enough of that music and deep plush carpet.
This is the best video for injecting Slime into Presta valves with non removable cores. The only difference was I didn't do mine on the living room carpet. Brahahaha!
Thanks, I remember when I was poor.
Used this for FAT BIKE tube. Superbly done and helpful. Thanks. Adaptations that proved helpful for me: 1) use a wire hanger (or any heavy-gauge wire) to push stem pin down into tube 2) use small vise grips (instead of clip) to gently hold the pin in place once it's chillin' in the tube 3) put your lips on the valve and suck in to draw the pin back into the valve if it doesn't slide down there naturally
Thanks for the tutorial. I have no experience with Presta valves and just bought a 29er with them. Shop said you couldn't remove the core for adding sealant. I called BS and came straight to YT and found your "how to" .
Thank you KriegerKrieg for this video!
For a few years, I had Flat Attack in my mountain bike tubes (with many thorn holes), and never lost any air. Recently I started riding 50 miles a day to lose 70 lbs over the last couple of months (yea me!). When my back tire wore down, I decided to swap the outer tubes so the less worn front tube would be on the back, while I ordered more outer tubes on Amazon.
Using screwdrivers to remove the tube, I punctured it (ARGH!), so rather than wait for an Amazon order delivery, I purchased a couple of prefilled Slime tubes from Walmart. I added Presta valve inner tubes, and Schrader adapters (because the Presta tubes were considerably less expensive for the highest rating), and Flat Attack to my Amazon order of outer tubes. In the last couple of weeks, my Slime tube got punctured, with a round hole the size of an average safety pin. I've had to air up my Slime tube every 2 or 3 days. Today it deflated too low to ride, and I had to walk my bike back home. (Never needed a bike mounted air pump with Flat Attack.) Then found out that Presta stems don't remove like Schraders. Thanks again for the video. My Presta tubes now have Flat Attack in them.
If you want sealant that actually seals, get FLAT ATTACK, not Slime!
Always have a pump, patch kit and spare tube when cycling. Sealants don't prevent all flats. Walking back makes no sense.
It works for me. I used a file to get rid of the stop at the end of the thread. Then the captive nut was free. Getting the valve core back in place was only possible after partly inflating the tube to clear the blockage.
I saved myself about $50 using only one can of slime, fixing 8 tires all with many punctures (we ran over 'puncture vine' or dry spiky goatheads). Shrader valves are dead easy but 6 of the punctures were on tubes with presta valves. The only difficult part is getting the screw pin to come back into the valve housing (4:35 on the video). One tube was so stubborn that the pin would not come back through the valve housing no matter how hard I tried. If you get into this situation, then as a last resort and this worked for me, is to poke an unfurled paper clip through the tube (thereby giving an extra puncture, which the slime will eventually seal) and push the pin back up into the housing.
It would be a good idea to file the tip before removing the captive nut, otherwise you could damage the thread or the inside of the valve.
Also, if you tie a thin fishing line to the core, the job can be done without removing the tube.
How would u tie the fishing line to the core? Around the valve stem cap thingy (the top that screws on and off to let air in and out)
Captive nut*
@@SEVEN-sg5rb the core shaft is being secured w/ a thin line so that after the captive nut is removed it can't be lost in the tube...
Removing the tube is not hard. Fishing line seems like more work than needed.
Thanks for the vid. I live in the middle of nowhere so I cant easily buy new tubes, and thorns are unavoidable. Ive switched to Slime because the Stans is great until it sprays onto your clothes and stains them. With the Slime I have a fighting chance of cleaning it off with some water if I get sprayed, and its much easier to obtain around here.
Thanks for the video. It worked like a champ for me! On another note, I was going to replace my rear Slime tube because it acquired too many thorn holes over the months and would slowly leak out. Unfortunately, the new Slime tubes I received from an online retailer had the wrong valve stem. So, I put Slime in an old, non-Slime tube that had a thorn puncture. I got a three hour ride with that tube yesterday, and it's still up to pressure this morning. Thanks for saving my ride yesterday!
You can patch a tube also
Love the music as well, its like mission impossible :D or in this case mission possible :)
Legends have it he still hasn’t had a flat 10 tears later . Same tube and tire .
The dramatic music made it feel like someone dismantling a nuclear warhead. This was a Jerry Bruckheimer production.
You never see his face, but it's Jack Bauer doing the slimin'...
Music to dismantle a nuclear warhead to ... nicely put.
super simple! I had my 27.5 mountain bike tire done in under 10 minutes...Thanks.
you pull the core out of a schrader valve and fill it.(takes a slotted tool to pull it out, but some stem caps have the tool on them)
the valve assembly will come out from the cap side.
Excellent, used this method to put stans in my CX tubes as the tyres won’t seat for tubeless, hopefully will work!
Great trick with the fishing line! Worked brilliant
My good sir, thank you for this video. I had no idea of how I was going to put slim in and you hasve explained it the simplest way. Thank you so much.
This is a very useful video--I had originally thought that this couldn't be done with a non-removable presta valve core. ALSO: Loved the music--it has a"Mission Impossible" feel to it...😛
Thank You for the video! I just got home from REI with new tubes and Stans sealant and realized it didn't come with removable core...
the valves didn't come apart as in this great vid?
Charles Saini they didn't come with a "removable" core but I was able to unscrew it off anyway.
I've used the same method you show in your video. Some of the Prestas with long valves can challenging to get the valve/pin back in place since it's not as long as the stem. Still, I've never seen one I couldn't get to work.
Did your fall in and where you able to get it out by using his method
The entire top piece of the valve can be twisted off the base. He didn't have to let that little piece sink in or even remove the tube or even wheel. People watching this first check if you have a removable inner core, will make adding sealant much easier.
Only if the tube has a removable valve core which this doesn't and is the point of the video. Many budget presta valves are solid and considered non-removable. Like you said if it had a removable core this would have been much easier.
it is a NON removable presta valve core like the one i got stuck with . they suck .my bike uses the Schrader valve but those tubes in 29 inch aren't available on this little island . so had to buy this crap . but im going to try this trick for filling with sealant . cool trick thanks
awesome video. thanks so much. my presta valve pin got lost in my tube and by using this video i fixed my front wheel. thx again!
I don't know how you got this to work but when I tried, the Slime would do as it's designed and would coagulate in the valve stem making it impossible to put any measurable volume into the tube. I tried all manner of squeezing the bottle, soft, hard, I made sure the valve was all the way out and rattling around in the tube. Then, I decided to give up, clean out what little was in there, and just put it back together, then I discover that the valve, itself, is keyed so after another 1/2 hour or so of trying to get it to the correct rotation so it would slide back into the stem, I just said screw it and got another tube. I then cut the old tube just to see what was going on and with just the valve stem itself, cut away from the tube, with no valve installed, and the bottle of slime, I could not get the slime to go past the valve stem except for a few drops. The harder I squeezed, the harder it coagulated. I don't know if you had some thinner or older formulation of slime but I would no longer recommend this method to anyone.
Agreed. This was one of the most frustrating experiences i've ever had. Slime mess everywhere, two tubes ruined. Never again.
yes. it happened to me too. This is not working
Wouldn't have been able to do it without the help of this vid!
Thanks for the help. I thought that I had wasted my money by buying the slime.
Simple and easy than expected. Thanks!!!!!
excelente vídeo y muy bien explicado, el mayor temor es perder el fierrillo que va en la válvula. but is perfect!
Worked like a champ! Thanks for the tip!
Excellent thanks very much! That saved me ordering more tubes, thought I'd really screwed up for a minute there. Think I can manage this though. Brillant cheers.
Thanks for the vid spot on , I set up Schrader tubes (using attachment and instructions that came with bottle of slime )and this vid for presta tubes with the other bottle of slime I had ,both set ups were easy .......don't follow the other plonkers on other vids using turkey baisters.
If I were, I would take the inner tube regardless. Slime does not protect on punctures that hit the wall you might rub against something get a flat.
Impressive! And great music. Thank you
great! i have 2 bikes and I've already put one bottle in one bike, but the second one, has this kind of valve...so i was wondering how to do it....so thanks man! gracias.
You used tyre sealant not tube sealant, did you notice any difference?
Okayyy that music made me feel as tho I was watching Crimewatch...
Thanks for the vid tho, especially the tip about the clip.
I've drilled out a few rims on my beater bikes to run shraders. I have not had a problem.
Some presta inner tubes you can remove the valve core, a lot easer
Thanks a million for this video i installed the slime product as shown . Awesome
DOES THE fastener hold the end of the core , or simply prevent it from retreating ? Is a longer valve easier to handle in the described procedure? Thank u.
Thank you for your tip! it works great and it really saves me money and headache!
as perfect a how to video on a great subject as i've ever viddied!
Mate defently wasn't sure that was going to work but it did thank god you are amazing at that and thanks for the video help
Glad I could help.
This worked fine for me....a bit fiddly but it works.
Tried this step by step, couldn't get valve core back out :( slime gone hard now.. Wasted new tubes and wasted slime £17 down the pan. Fuck slime! Saving up for tubeless set up lol was worth a try
Gaz Dav its a river of slime
Won't work with the Presta adapter. The valve in the Presta blocks the Slime from going in. I have a video showing basically what this does, but also one showing how to change your Presta wheel to a Schrader so you don't have to deal with crappy Presta valves. I have yet to understand why these are so popular.
Presta valves are much easier to lower tire pressure on the go
Jeez that music, I felt like i was going into battle with a fucking wheel.
You make this look so easy - can you come round and change mine for me???LOL
excellent and simple especially the bulldog clip tip thanks
Thanks, great video quality and technique
Very nice. You just saved me a few bucks! Thank you!!!
Why not just make a small nick in the tube, inject the sealant through it and then patch it with a conventional puncture repair patch?
That music.
Fitting for dealing with a presta
Exactly what I was looking for, thank you very much!!
Was it really that easy to hold on to core & refit it? Or have you had plenty of prior practice before filming? Plus, visual instruction with suitable background music is so much better. You Tube have too many irritating egos that can be annoying.
It was easy, as I remember it. However I have switched from slime (glycol and cotton/rubber chunks) to stan's or truckerco cream which are latex based tire sealants. I have run both of those in tubes and tubeless setups. If you are checking out tubeless I would recommend the "ghetto" style tubeless with gorilla tape and stan's sealant. It worked great on this bike.
@@KriegerKrieg Took the easy option left both wheels with the cycle shop. Although repairing five punctures, I was pissed off at that point. Had a cut through the side wall, needed new tyre as well. Had really bad luck that day. Plus, I hadn't seen your informative video.
The best so far
Patrick's right, instead of unscrewing that little nut, go lower, where the plastic cap screws on undo that with the plyers.
Nathan Scott it looked like a none removable valve core, guess he not discovered continental tubes
What kind of Slime cap is that? Cannot find one that fits presta valves.
Brilliant video 😎
I can remove the small but but the valve stem won't slide in what IAM I doing wrong.
this really saved me, thanks man!💪💪
Do you think I'd be able to do this with the bottle for Schrader valves? I'm assuming it would just make an external mess, but I'm unsure.
Thank bro! You're the Pro!
Legit. I appreciate it.
Bro you are a genius, thks
Thanks for the video and info.
Awesome video. Thanks
Good post, thank you!
Many thanks
Thanks will try this.
i used slime in both the front and rear and i run over all kinds of stuff from glass to huge bolts and no flats plus the tires have kevlar so double protection lol
I can't quite put my finger on it but I feel like I should be robbing a bank instead of adding slime to a tire.
Right when I take it out of the pump, it loses air, I tried again lose air, help?
Thanks it's work perfectly!!!
This is unbelievable. I purchased the slime and I was very confused as to how I could get through the stupid presta valve tubes that I have. A Schrader valve is to wide and won't fit threw the holes on my rims so u unless I get new rims which I can't afford I am forced to use presta vales . I didn't see it on the bottle at first but they even put in red on the bottle for Schrader valve only . Now why the hell do they say that when they could give the instructions you show us here. it was easier than I thought jt would be . Companies just LOVE to bullshit more and more
anybody know if instead of taking the stem apart, if this would work with the presta adapter?
You are THE MAN!!
My clip broke and valve fell In anyone know how to get it out?
do it like you would a tie cord on a sweat jacket that has pulled out.
Odd question but do you know if anyone has tried this for road tires with presta valves? Basically this would be useful if one was going for a long distance ride and didn't want to tack on extra weight of having a spare innertube.
Had the same question. Apparently, there's no room for the slime to expand unlike mtn bike tires. Rd tires are very thin and so r the tubes so take a spare.
It is not coming out of it clean as in it is not fitting the groove
Slime prevent flats, i assume?
Sure thing and thanks for your video again
Dude, genius
Thanks that helped heaps!
Glad to help.
Does slime work to fix a flat?
no it dsn't because u need to remove the stem to introduce the slime
Sick ima try this right now!
Worked like a charm ,had lil trouble with valve but it came through, gonna see if tube is still good in the morning..
great! thanks !!
how much u used in one tyre
tell me in ML bcoz i m not understand u
This takes more effort than just replacing the whole fucking tube ...
Hello do you know how much of the liquid oz I need for a 29er?
4 oz (1/4 of this bottle)
thank you.
Awesome
you can just remove the whole valve assembly as it is screwed on to the main tube
Patrick Dixon no you can't with many tubes
Nice video and where you learn this from
how much slime is used in a 29er tube ??
Saludo KriegerKrieg, buen vídeo amigo bueno quisiera que me ayudes con el precio y el país donde lo venden, ante mano gracias.
If you have the right tube, you may not need to remove the tube at all! Simply remove the whole valve like this /watch?v=DObnGysYTlc
Video Unavailable.
But I'm guessing it's the other type of Presta Valve - the title of this video says it is for "Non Removable Core" type valves.
Can this be done with a road bike tyre??
Should work just fine, I would recommend a latex based sealant like stan's.
