Review on 🔧 Set of 2 Stainless Steel Dual Tire Extenders, 7" / 180mm Tyre Valve Stem Extension Adaptors for Universal Motorcycles, Bikes, Cars, Trucks, Scooters, RVs, Trailers, and Vehicles by Ben Cooper

I bought these to inflate my motorcycle tires. My valve position prevents me from using an inflator with a built in pressure gauge, so I put it on for easier access. I don't leave them on the bike, I only use them when inflating. I've noticed that they can and do leak, which seems to be the most common complaint, but they work well enough for my needs - I just played around with them until they got relatively tight. I keep one in the garage and the other in my saddlebag. However, I wouldn't trust them enough to be securely sealed on the tire to stop them all the time. But cheap enough for what they do.
