Does any one make a push on converter one to another half my gear has one half the other

The one on the right is a pcl, the one on the left looks to me to be a cheap+ nasty chinese job. Adaptors can be made by fitting different bodies and "tails" together. In an ideal world it's nice to have all the same.

Does NPT refer to the threads, National Pipe Thread?

More on the variety of connector profiles:

Yes it it does actually. When I started to look up air couplers they were listed as NPT Air Couplers. I have a few older ones that are bayonet type fittings, where you push them into the line and twist to lock them together. But I haven't seen them in years. As I purchased new/more air tools I didn't feel like swapping my fittings from tool to tool, I just want to fit and forget and not have to swap before use. So I splurged and changed everything. Now you don't see the bayonet types. My preference is for the brass ones as they are non-sparking.
