Reddit reviews Gorilla Automotive VS406C Flush Mount Valve Stems - Smooth Cap

Rubber non TPMS valve stems are fairly uniform across the board from automotive wheels to hand dolly wheels. If the rubber valve stem isn’t sealing properly and it’s a aftermarket wheel then I would say it’s safe to assume the valve stem hole has been bored out.

How many wheels are leaking, and for %100 sure it’s the valve stem to wheel mating area leaking and not the wheel bead?

Edit: just read your old posts and did some digging. Your wheels won’t fit the standard rubber valves stems, they do but they don’t. You need another flush mount kit to go back into the original holes. They should seal on their own with the rubber gasket supplied, if not then you can try some bead sealer also in Conjunction with the rubber washer on the valve stem base.

I have a Boxster S with Antera rims, but I can't find an adapter to fill a flat tire with the flush-mount valve stem.

I've already purchased and tried this from Gorilla (www.amazon.com/Gorilla-Automotive-VS406C-Flush-Mount/dp/B000CMJ3L8), but the filler tube is too big to fit these rims. I've contacted Antera, but no response from them yet either.

Any suggestions? Thank you!
