i72 Tubeless Valve Stems 40mm Presta Pair - Brass Made with Core Remover Tool, Round Rubber Base with O-Ring for Better Sealing

Not much to report. I screwed these valves in, put some sealant into the bottom of the tire, seated it on the rim a little bit, compressor on, et voila, I am riding tubeless (with tubeless-ready wheels, of course). No leaks from the valves or anywhere else after 2 weeks.

Great product at a cheap price. Sealed up great in my tubeless setup and couldnt ask for more

Used 1 in gorilla tape on rim. 3 oz of stans and these. Worked like a charm.

Exactly what I needed and as advertised

Arrived promptly with no surprises. What more could a customer ask for?

Worked great with Stans tape on a road bike rim. No issues - sealed on the first try.

Easy to install and, so far at least, properly functioning, these valves were installed on wide rims for 2.8 width tires, using Gorilla Tape to seal the rims for tubeless conversion. No leakage, and no clogging, as yet; but its only been a week, so I cant yet comment on any long term experience with them.

They installation was simple. The rubber ring was a nice addition to keep the seal air tight. Good to know you can get good quality tubeless components without spending a small fortune.

My tubeless tires and wheels worked great for years but the integrated rubber liner and valve stem developed a leak where they were fused together. I added new tape around the wheel, rotated the rubber liner, poked a new hole in the liner and installed these valve stems in place of the old, fused ones and it went in perfectly. It has been a couple of months now and the tires have held the same air pressure the whole time. Job done.

Great valves for the price! Get these instead of the premium brands!
