Yeah, but there are some cases where getting a new tube it's not worth it neither. I have an inner tube without a single patch and there is a leak on the base of the valve, even nearer to the valve stem than the one on the video. I won't throw it to the garbage without giving some fight first.
While I am about to try this technique 1st, I did find that Milton makes entire valve stem replacement patches.... search for Milton 462 and/or Milton 473 for them. But once you try one of these entire valve stem replacements you are stuck with them and if they don't work the tube is trash, while trying this 1st gives you a 2nd chance with one of the Milton stem replacements if this doesn't work. I have a rear tractor tire with a cracked tube stem, this tube is only 3 years old and costs over $100 to replace so.... what do I really have to lose but a few more days time? Just wish it wasn't 100F outside here in Texas right now... ughhhhh! 😞
was the 2nd leak more than a pin hole size? Curious as to why you would need to use the heat to seal a rubber patch repair.... I've never done that on probably 70+ tube repairs I've done... but if the hole is more like a snake bite cut or tear does this process kind of melt the tube rubber and patch rubber together to effectively close a slit type of hole. Then I might have to try sometime. Also, has anyone ever had luck trying something similar on a presta valve at the base where the valve stem is seperating from the rubber.
ever try the patch over the stem method on the presta??? I'm tired of throwing away tubes because of that failure... If anyone has tried it successfully I'd love to know...
John GTA. I just fixed my inertube valve its verry simple. I don't do the heat sink and torch. I just use a hairdryer to dry it faster and let it dry all night.
John, there's no easy method for a big hole like this. This is just a concept so you can apply to fix any holes on your tube, not just for a big hole like this. If it can patch a big hole like this, it can patch any hole.
If such a large ready made patch is not available, one of the options is to make your own patch from an old discarded tube. Just cut a large circular piece from a clean part of the old tube. It will be good enough.
i tried large patch, pressed it down with weights for almost 1 hour. no leak on water test - but when u fill up to full pressure (after putting inside tire) - the hole seems to expand and - FAIL. it has happened many times, so now - only if its a small hole -, i patch it. large hole - get new tube
@@iwatchwithnoads7480I'd still rather pack spare tubes than deal with patches not working right, which in my experience with valve stems, is the norm. Pinprick holes on the body of the tube, those are easy and worth patching. Valve area, just chuck it, save yourself hours of wasted time, patches and frustration.
