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

The products were as advertised and worked excellent.

These valve stems do not work with the Shimano rims so they were useless to me.

I should have read all the reviews. Like several other reviewers, after setting up my new tires and wheels, and installing sealant, these valves leak at the drilled rim hole. They dont seal properly. Big mess to re-install my tubeless tires with old Stans valves which fixed the problem. Mistake to buy these to save a few bucks. Stick with name brand components. Not at all sure about all the positive reviews on Amazon. Read and believe the negative reviews!

works well and seals tight for my 27.5 tubeless MTB tires.

Was reasonable

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

Received the tubeless valve stems promptly but haven’t used them as yet. Appear to be solid quality and the perfect size.

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.

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

Worked great
