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

They hold air

Install was easy.

Use these to recharge spent aerosol cans that still have product left inside (YouTube it, it actually works--but be sure to wear disposable gloves). Have already paid for themselves.

Installed these on several different cars with steel and aluminum rims. Had several returns due to tires going flat and found that these dont seal to the rims like they should. I replace the stems to prevent problems not create them. I was not happy and neither were my customers

Good price and quality. Used to make old ford tube rims tubeless.

They have held air for about a month now. They fit well.

Good

I was amazed how much less these costs than thru the local parts stores.

Purchased for my BMW, Just awesome High Pressure Rubber Tire Valve Stems. Great purchase.

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.
