Help identily male quick-connect

[sixdogs]

OK, I understand now. Yes, there are times Kubota connectors give a little trouble and if the ball type male end doesn't work it sure looks like the end with the flat spot on it will work. When I have a problem I just swap the ball types around and a different one has always worked for me. I think the OP has something else going on if he is hardly any flow going through.

Maybe I buy a better quality of tips, keep from abusing them or keep my fluid cleaner. I always shut down, relief pressure via the system spools or reliefs and have an easy time disconnecting and reconnecting. I never, ever "manually" relieve pressure by striking or forcing a tip, I have dozen of connectors, 90% the ball type and have no problems. The ball types clean up real nice before connecting, maybe that is my key?
