got a flat-face setup on a skid steer. is this plug the kind that swaps with the 3/8 HTMA couplers?
Answer by: Customer Support on Jun 10, 2025, 12:00 PM
For 3/8 size HTMA interchange, this plug is called out as interchangeable with HTMA couplings in that size, and it is a flat-face (FF series) male half with a push-to-connect end.
