This is a simple metal double sided air chuck that you would attach a 1/4" NPT plug onto (Suitable 1/4" plugs listed below). With your 1/4" NPT plug threaded on, you would connect directly to an air compressor hose. (Suitable hoses listed below).
This is a closed air chuck which means air doesn't flow out of it until the valve is depressed when attached to the valve stem. The air chuck has a nice weight to it, unlike ones you would typically find in a corner hardware store. The air chuck also has a red rubber grip on it which makes it comfortable to hold while filling tires.
