Wanted to find a heavy duty extra thick hose - couldn't find it at Revain; so i bought this at; I'm pretty sure I got both stuck and leaking during installation, so I patched both; Ironically, this is the first time in 55 years that I've pinched the pipes with a crowbar during installation - so my skills are weakened(?). I don't really know the answer to this question - but there was good sampling to suggest I was the culprit, lol. So I bought a $10 SLIME patch kit and patched these two MISSION tubes in the same spot. The only other issue (which I haven't addressed): Stem position/angle: it's in exactly a weird spot and comes out of the car wheel at a weird angle - but I can live with that; Third, I add SLIME to almost anything that doesn't see DOT (highway) situations - for example bikes, motorcycles, lawn mowers, etc.; and I use it in my car too - the last two decades; This time I plan to use Stan's latex - it's thinner and easier to "harden" and I think is equivalent to slime for regular or small holes or leaks.
