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

I thought I would save money and purchase a set of these for my Stans ZTR crest rims. I couldnt get these to seal properly without air leaking at the stem. I tried both valves that came in the package and had the same results.

Good for the price

Great stems at a great price.

Love the rubber o-ring that keeps the tool on where you need it! These worked great for my tubeless tire conversion

Just what I was looking for and fast delivery.

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

Its been a month and holding good!

Best Tubless valve stems at a Great price. The 40 mm length is perfect. Much better than the standard length. The Buyer gets you the items super fast as well.

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

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.
