ACCRETION 4 Pcs TPMS 20008 Rubber Snap-in Tire Valve Stem, Tubeless Valve Stems Suit for 0.453 inch Rim Holes on Standard Vehicle Tires

I bought this to build a DYI CO2 chamber. It works great and very pleased with it. It is still going strong after 5 years. Please note, if your building a CO2 chamber to always inspect all parts for leaks before and after use. Works well, good quality, easy to use, no leakage as long as installed properly and good value.

They worked great and inexpensive.

Excellent product, fit properly and easy to install, I hope will have a good duration.

Does the job.

Muy excelente

Have a wheelbarrow with 15" Diameter tire . It was flat so i used my compressor unfortunately the stem popped off due to the rubber corrosion. I have never replaced a stem before in a tubeless tire but i decided to give it a go as replacing the same type of tire would not be worth it considering how often it is used. Popped out old stem, measured hole size and ordered this item as it indicated it was the size i needed. Had to pry the tire back near the hole which was a bit difficult as it was a stiff old rubber tire but after a few choice words and a couple of clamps it was finally far enough back to insert new stem from inside. used pliers to pull and twist and trying not to squeeze pliers too hard to avoid damaging inner workings of stem and VOILA ! ! done. Maneuvered the edge of tire as close to edge of rim as possible, fill with air and pat myself on the back for a job well done.

got these to throw into tool box. You never know..

Works great for my purpose!

Dimensions exactes. Produit solide et bien protégé contre la corrosion.
