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

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.

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

Just what I was looking for and fast delivery.

Was as described and shipped fast

Its cheap and it worked!

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

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.

As described.

Ive gone through a lot of valve stems in my time using tubeless tires. These are by far the best-built Ive seen - a bit more substantial than other brands Ive used. They also have removable cores, which is huge for those of us adding sealant without wanting to pop the tire bead off. Im going to see if they have a 60mm length version for use with more aero-style rims.

They are inexpensive and they work.
