2 PCS Car Portable Air Pump Connector, Alloy Deflated 90-Degree Locking Tire Inflation Chuck, Multi-Functional Accessory, Suitable for Bicycles, Motorcycles, Cars (Gold & Silver)

Works as well as the highest prices alternatives. Sturdy.

Extremely tight fitting!I do a lot of off-road driving with my Jeep and will reduce my tire pressure before hitting the rocky trails in Arizona. One of the things I did not like about my compressor that I use to bring pressures up to spec, is the screw-on/off end that would leak when trying to get attached and disconnected. These connectors are the same size and thread as the valve stems and would allow a quick connection. The only issue I have with this connector is that it fits extremely tight over the valve stem and requires a lot of force on the locking lever.I keep up with my reviews and will revisit this one should the need arise.I give these connectors my Big-Foot “Stomp” of approval and 4 stars!

I added this to small portable tire inflator that has the screw on type connector. It gets annoying having to use the screw on connection with all tires, especially between spokes. This adapter makes the job quicker and is easy to remove when I need to use the screw on connection. I'd been using an extension hose, but this is much more compact to go along with the small portable tire inflator. Overall I am pretty happy with them.
