I need help finding out what these female connectors/attachments are called so that I can buy them for my air tank project. Basically these are found on those portable air compressors which connect to schrader valves by screwing them on. I don't want those quick connect head types, just the regular screw on types where the knurled part rotates freely without rotating the hose attached to it. The hose I will be using is the 1/4" compressor hose and the valve I have is the generic tubeless tyre schrader valve.
I initially thought these were called barb connectors but I found out they don't have that push pin inside them which releases the air once the connector is tightened to the schrader valve.
Here are some images
I reckon something that looks like this is preferred since it's easier to attach to my hose without any crimping.
