140mm Brass Auto Tire Valve Extension Adaptor, Air Tyre Stem Extender Inflation Stright Bore for Motorcycle, Bike, Mower and Scooter(140mm)

I used it for my scooter and it is very good to work with.

Very good tool especially if you can’t reach the stem with the nozzle

Working on tires just got easier this tool is good to work with

Needed to inflate electric scooter rear tire

First time I tried, and it didn’t work at all. Disappointed.

Works perfectly! Nice product!

easy to get air in

This is a well made product. I bought the 100mm size figuring it would easily clear the E450 front hub caps. It is long enough but the nut up near the top used to tighten it where the hub cap cutout is. I replaced this with the 140mm size made by the same company. Just be sure you know where that nut will be before deciding what length to purchase.

This was my 3rd attempt at getting an extension valve that would work with my electric unicycle’s tire and I’m happy to say it works perfectly! Excellent build quality.

Scooter rear tire had no room for a air chuck This worked perfectly. I air up the tube in the tire, unscrewed this extender an put it away in my tool box. Excellent piece
