got a 1/4 nptf air line, is this the right female quick disconnect or am i fixin to order the wrong half

This is the female half (socket) with 1/4 NPTF on the port, and it meets the US Industrial Interchange standard (also listed as ISO 6150 Series B and A-A-59439). If your plug is the same interchange style and you need a 1/4 NPTF female socket, this matches up.
