Stans 44mm Tubeless Valve
Perfect for tubeless! This longer 44mm Presta valve stem is perfect for converting most Road 700c rims to tubeless using NoTubes 21mm yellow tape. You can also use this for more valve length with extra-deep carbon MTB rims. This valve will seal most existing rims with an inner valve stem hole diameter of 6mm - 8mm. Rims with no inner spoke holes such as Mavic Ksyrium and Shimano Ultegra will not require the yellow spoke tape, just the 44mm valve stems. Deep dish rims will require a valve stem extender. Valve stem features a removable valve core which allows for application of NoTubes tire sealant.
Fits most road wheels & rims, a conversion kit is required for non-tubeless rims. DO NOT use with non-tubeless approved rims.*

I recommend pumping up a tire without sealant to test for air leakage. I can almost guarantee if you hand tightened the valve nut, you'd still be leaking air out of the valve hole, due to not being seated at the base. I have a carbon rim with a drain hole drilled into it, leaking out the air... would've been spitting out sealant too, if I got too ahead of myself. What I did was use pliers to seat the valve, then loosened it, and retightened it by hand--not too unlike seating a tire at 40 psi and then dropping it back down to a more ridable pressure.
