    Tubeless - Leak by valve - will adding stan's fix it?

    I have a small leak coming from the valve of my tire. It is a new leak, was able to ride about 50 miles on it before this happened. Will adding Stan's sealant fix it, or do I need to retape and re-add sealant.

    Generally speaking you would want to try to tighten the valve or possibly even uninstall and reinstall it to try to get it to seat better. With that being said, I have a couple hundred miles in on a recent tire bead that I was able to seal with Stan's.

    somehow the leak that began in its own (sprung overnight), was fixed on its own. guess stan's works?

    Indeed it does, chances are you'll find a blob of stans around the valve next time you have the tire off. I usually put a drop of loctite on the outside nut before tightening it, granted use one that isn't permanent

    Tubeless - Leak by valve - will adding stan's fix it?

    My leaky valve problems usually appear immediately. What I do now is apply a dab of rubber cement or silicone sealant to the rubber in the valve before inserting it, then torque the valve nut as hard as I can by hand to make sure it is airtight. Then mount tire, squirt sealant thru the valve, pump and seat. This cures valve leaking for me for as long as the tire stays on the wheel.

    it is my opinion that the rubber on the valve needs to be a little bigger to ensure a tight, sealed fit around the valve hole

    Indeed. You can buy 2 Stan's valves @ $16.00/pair and the rubber on the valve is tiny.

    Meanwhile, you can buy Q-tubes with presta valve & removable core @ $5.04/ea. and cut the valves off with as much rubber as you deem necessary.
