4 Pcs Valve Caps Stem Extension 27mm Tire Valve Extenders Brass Tire Stem Extension Wheel Tire Cap Extender Adapter for Car Motorcycle Truck

Work really well, no leaks!

I like these on my wheelchair as the extension stops the air chock from pushing the nozzle into the tire through the wheel when the air is low. It also makes it easy to fill the tube with air.

They did the job, we needed for hubcaps, and they work as intended.

These work, just wish the PSI rating was higher.

Perfect for short valve stems. Extended just enough to properly fit an air chuck. Doesn’t leak.

As the old saying goes....ya get what ya pay for and I should've known better, but the reviews seemed to be fairly positive, so I thought what the heck, I'll give em' a try. Epic FAIL!! The 1st one I put on seemed to work properly. The 2nd & 3rd didn't work at all, which I don't even know how that's possible and the 4th one leaked so I took it off, checked the gasket and made sure everything lined up, put it back on and it still leaked. Needless to say with 3 being bad it made me leery of the one that did appear to be working correctly so I took it off fearing that I'd wake up to a flat tire and with being disabled the last thing I wanna do is have to try and change the tire on an F250 SD 4x4 lol. I truly wished they would've worked as they were the perfect size extension and just what I'd needed. Whomever put tires on our truck before we bought it used the stumpy metal valve stems and it ends/lines up right at the edge of the rim making it impossible for someone that has hand dexterity issues to screw on an air pump to fill the tires. Same lesson proven yet again of getting what one pays for so shame on me lol. DON'T WASTE YOUR MONEY OR TIME!!!

works perfect for making it easier to put air in mobility scooter tires

This is a great product, replaces the cap on your tire. easy to put air in your tires. Just screw on where your tire cap used to go no cap to remove and no cap to put back on. I recommend it. I’m gonna to buy another pack of four for my other car

Diese Ventilklappen sehr sehr gut aus und passten bei meinen Autoreifen.

This is a must have for air tube electric scooters especially in the UAE because the valves themselves are small and cannot fit a normal cycle pump adapter onto it. Amazon delivery is so fast that I had this delivered the next day and It worked as intended. Just need to screw it in until you can hear the air leaving once you press on the cover on the top of the adapter. Then just put your cycle pump on it and pump away!

They work, nuff said.

Funktioniert als Verlängerung für tief liegende Ventile…
