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

Worked great

As expected.

Each valve stem came with a small rubber o-ring, but there was an extra larger o-ring, and didnt know what it was for. I had problems with air leaking from the valve stem. I know not to over tighten the stem when installing, and made sure it was properly seeded.

Exactly what I needed and as advertised

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.

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.

These mounted easily and had no leak issues at all.

Was reasonable

Works great, great price

Used for tubeless conversion along with gorilla to 1 inch tape and si far so good. 3 rides and no leaks.
