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

I have a standard rim and the rubber part was slightly too big to fit in the hole. I ended up tightening the nut really tight and it still seals so it isnt a huge deal. The stems seem solid and durable. Pretty happy with this product. Only knocked a star off because of the fit.

Great valves for the price! Get these instead of the premium brands!

Works great seals well onto the rim.

Arrived promptly with no surprises. What more could a customer ask for?

Works as advertised.

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

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!

Seated and held air with no issue at all on my Bontrager wheel set. Works as expected.

They leak at the base no matter what you do. After spending hours and hours trying to fit these valves (where other valve types would do), I took time to actually review all these 5 stars reviews and realized they are almost all fake. These valves are garbage. Invest few more bucks and get Stans.

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.
