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

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.

Was getting a leak around the valve stem on a mountain bike. After put this in it fixed the issue. Great product. Need to sell it with larger quantity.

delivered quickly and was as advertised.

The thing that sets these valves apart is the tiny o-ring thats inset within the threaded nut, adding extra seal outside the rim. This also keeps the valve from wobbling loose. These will be my go-to valves for tubeless. Better quality than Stans, imo, and thats saying something.

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.

Sealed well. No issues. Included tool was useful and stays in pack

Worked great. Making wheels tubeless isnt for the faint of heart, but these stems worked great.

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

As expected.

The valves are absolute garbage.. Wish I could leave no stars at all. They leaked, tried everything under the sun to make it work but they’re useless.. I would not never buy it again..
