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

Very nice quality and reasonably priced .. worked perfect for my tubeless tire conversion !! .. will definitely buy again for the next set

Quality was good and conveniently came with the core tool. My only problem was that the valve stems wouldnt seat completely when installed (WTB i19 wheels) as they were slightly too wide and the rubber too hard make an airtight seal, even when the nut was tightened with pliers.

I installed these on 4 fat bike wheels. They are holding air just fine after adding sealant. Buying more for my gravel bikes. So far so good. If I have any issues I will for sure reply to my review.

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.

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.

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.

Could never get them to stop leaking.

Its been a month and holding good!

Worked great

Great worked as expected
