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

Includes a nice embedded o-ring in each nut so they never come loose. Helps with seal and prevent scratches, as well. A spare o-ring is included just in case and the valve core tool is a must have. Great size that fits almost any rim. This will be my go-to from now on!

Great if youre trying to do the Gorilla tape method

Product is great, as expected

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.

Easy to install, sealed quickly, no leaks, and nice additional little tool.

They are inexpensive and they work.

Valve leaks around the base like a few other reviews said. Spent hours trying to figure out the problem, thought leaking at spoke nipples was due to a leak in the tape but came to realize it was the valves. Adjusted multiple times and added sealant but nothing will get these valves to stop leaking. Don’t waste your money or time buying these!

Was easy to set up

These are 100% good. Should be.
