🔧 Enhance Your Tubeless Experience with Fouriers Tubeless Presta Valve Extender Kit Extension (Pack of 2) Review

Very happy with the quality. The diameter of the threaded shank worked well with the ability to lock the extension in place.

They work quite well. I had to put teflon tape on them to seal them. Maybe they would work better with low pressure units or sealant, but at street pressure with hoses the o-ring doesn't seal. Otherwise a fine extension with a little extra effort.

These extensions do not hold the seal well, they leak incredibly quickly compared to other brands I use. The tool provided is great and allows you to apply some torque to the extensions and valve but as I said my tires went flat overnight if not hours later that same day. I was lucky not to install them during the long journey.

Used to lengthen valves on Conti 700 x 25-32c chambers. The tool provided made it easy to remove the valve and reattach the extensions, and the rubber grommet on the extensions holds the pressure very well (I didn't use tape although I have one). I run tires at around 95psi and can lose 1-2psi in a week. This is exactly what I need for wheels with deeper rims, and it allows me to carry a spare tube with only one valve size (keep a valve tool with a spare tube for road use).
