I have (don't ask me where I bought them because I can't remember) a whole bunch of these quick couplers, engraved "PERFECTING AG". All are 1/4 " NPT. I need to buy more, really don't want to get all my invention's connections to be different. Well for the life of me I can not find these anywhere. I have ordered 1/4" couplers with other names and they just don't match.
This is what they look like:
If anybody can I'd be very appreciative !!!
