In this video I'll show you an easy way to inject Stan's into a tube with a non-removable core without having to remove the valve nut, or your tube from your wheel.
Nobody else on RU-vid says this is possible your way. I just did it your way and it works no problem at all. Please come back to RU-vid as your ideas are great and so is your sense of humour. Thanks🙂
I'm glad it worked for you! Regarding new videos, I do have new ideas to share but honestly I've just been lazy to make them. But thanks for your encouragement! I'll try harder to motivate myself to make them.
A couple of thoughts: 1. You don't point this out, but I assume that you let all the air out of the tube before you inject sealant into it. That may seem obvious to some, but in step-by-step instructions like this, details can be important. 2. I tried your technique with Slime and it did not go well. I know that others have asked about viscosity, and perhaps Slime is too viscous for this process. From watching you pour Stan's sealand into the syringe, it looks much thinner (less viscous) than Slime. Are you pretty happy with how Stan's sealant performs? Maybe I will try some. 3. I did not know that "topping off" sealant in a tube that already has sealant is advisable. Have you seen any issues with the sealant performance after "topping off"? 4. Thanks for the video, and for the specific details (like the size of the tube you use). That is very helpful. 5. Finally, thanks for being so diligent in reading and replying to all the viewer comments and questions. It is so common that viewer comments just get ignored, so it is very helpful and refreshing to find someone who actually revisits their videos and responds to comments. Keep up the good work. I am now a subscriber and look forward to future videos.
Hi Norman, thanks for the comments, I appreciate it. Regarding your questions: 1) Yes, you have to let out most of the air otherwise it'll blow back at you. Good point on the extra details: I'll keep that in mind for future videos. 2) Yes, slime is much more viscous than Stan's and as you found out, it did not work. Stan's has a consistency of heavy whipping cream and flows much more freely. I've been using Stan's since he first came out with it in the early 2000's and I've never used anything else. It has performed well for me over the years especially on thorns, nails/screws, pinch flats and small glass cuts. However, if you get a gash that's too big to seal it won't work. That happened to me once but luckily I had a spare tube I always carry. 3) From my own observations, Stans will eventually dry out to some degree and that's the reason I "top-off" my tires (and peace-of-mind, LOL). I use 700x28mm tubes and I usually put 0.5-1 oz (15-30 ml) on a new tube, and ~10 ml when topping off: this works fine for me. Lastly, if you want to try Stans' they sells a 2-oz bottle for a few dollars. Good luck and thanks for watching!
No, the tire was not punctured. However, I add tire sealant to my tires as a preventative measure. If you run over a thorn, nail or something sharp that punctures the tube, the sealant seals the hole almost instantly: sometimes it takes a few revolutions to fully seal. It is not foolproof and if the hole is too big to seal, you'll lose your sealant and have to stop and replace the tube. Thanks for watching!
The simplest and most straightforward method for applying sealant to a non-removable valve is to puncture the tube, inject sealant, seal it with a tire patch, and then inflate.
You can certainly do that. However, you've now compromised the integrity of the tube. The patch is now the weak link and if the patch doesn't hold, you've ruined a perfectly good tube, and possibly harm to yourself if you crash.
@@teddeguzman5298 I have no issues with the patching method. Since I have no access to dirt jumps and mountain biking, my playground consists of a three foot steel ramp, stairs, walls, elevated walkways, and pavements in the city.
Hi! I run 28mm wide road tires and use about 1/2 - 3/4 oz. (15-20 ml) on a new tube. After a few months I'll top off with about 1/2 oz. when I remember. Thanks for watching!
The difference is in the viscosity. Stan's has a viscosity similar to heavy cream whereas slime is more gel-like. This method will NOT work if you use slime: it's too thick to push through the valve stem. Hope this helps and thanks for watching!
Yes you do! If you don't, you'll have a big mess since the tube might come loose and spray all over the place...been there, done that, LOL! However, if you have trouble injecting because the valve won't open up, a teeny-tiny amount of air in the tube can help. Good luck and thanks for watching!
Hello! My Presta valve is alot longer than yours about 1 and half inches est. Would the tube go all to end since it's so much longer? I just tried it about a little over where the valve core is and it didn't seen to work.
Hi Christina. Try pushing in the tube a bit farther in: doesn't have to be all the way. Also, try jiggling the valve not only back & forth, but also a bit up & down, while trying to gently force the sealant. It is not unusual to have difficulty initially, but keep jiggling and the sealant will eventually pass through. Also make sure the valve nut is fully unscrewed. Sometimes I find it helps to put just a little bit of air in the tube. Some tubes work the first time, some don't. Thanks for watching!
Yes, a little bit can spray out. I usually spin the wheel first and then use a rag to cover the valve before I release the air. I also move the valve to the 4 or 8 'o'clock position so there's less sealant coming out.
Type this in the ebay search field "60cc 2 oz syringe" and take your pick of sellers. The tube can be bought by the foot at your local hardware store. Bring an old tube so you can see which size fits the presta valve. Hope this helps and thanks for watching.
Does the sealant injector work with Flat Out, which uses Kevlar? My understanding is that the sealant injectors only work with low vescocity sealants, and I don't know whether Flat Out is low vescocity or high vescocity (not to be confused with velocity). Thank you.
I don't have any experience using Flat Out, but out of curiosity I watched a few videos on RU-vid. It looks like it may work with the injector I used even though Flat Out is more viscous than Stan's. Since the injector has a tapered tip, you can cut it to make the opening bigger to allow the Flat Out to flow more easily. However, because Flat Out is more viscous than Stan's, it may not flow easily into the non-removable presta valve of your tube: if that is your intent. Good luck and thanks for watching!
@@melonyclark9413 Were you able to get this method to work with Flat Out? Just got a new bike with Prestas and the cores are not removable, so would love to know if I can try this method with Flat Out.
Я тоже так подумал и обрадовался. Но на самом деле он не зальется. Качественный антипрокол в основном с крупинками и густоват. На видео какая-то жидкость странная.
If it’s not a silly question, why did they manufacture Presta valves with a non-removable core? The removable core seems to be easier to work with and is more like the Schrader valve for working on.
That is a good question. My only guess is that it was done for cost-saving. Tubes with removable cores tend to be a bit more expensive and need a small tool to remove the valve. That was the main reason I didn't buy tubes w/removable cores. Thanks for watching!
Presta valves are used because they are superior to schraiders in bike applications. Presta's allow tire pressure to push them closed even when the tip is not screwed down. they also are lighter. on MTB bikes they also are easier to clear mud pack/debri from.
@@crabtrapok, but why make the valve core non removable?!? ..this shud be an industry standard! mnfctrs cutting corners to save in cost, cost the user in the long run!..
@@KickTurner as i stated: the pressure in a presta push it closed. There would be no way to make it removable with out increasing weight and size. Also presta's are used on high pressure tires. U dont need parts ar 120psi coming lose and launching at someone
