Review on 🚗 Enhance Tire Safety with SAMIKIVA Brass Rubber Seal Valve Stem Caps - Universal Fit for Cars, SUVs, Bikes, Trucks, Motorcycles - Dust Proof Covers for Ultimate Protection (Silver, 8 Pack) by Jake Jones

These are valve caps! They look good and provide a good seal. Since it's brass, I hope they don't corrode when exposed to road salt. So far, so good! I use a socket to give them an extra setup to prevent them from being stolen. (Yes. I've had valve cap thefts before!) Just be sure to toss a wrench in your glove box or tool box so you don't snap your fingers trying to get them off.
