Question by: Dwayne E on Mar 1, 2026, 6:51 PM
got a flat-face setup on a skid steer. is this the female half that matches the 3/8 size HTMA style couplers?
Answer by: Customer Support on Mar 3, 2026, 4:30 PM
For 3/8 inch HTMA interchange, this socket is called out as interchangeable in that size and it is a flat face, female half quick disconnect (FF Series) with a sleeve lock.
Question by: Merle E on Apr 11, 2025, 9:13 PM
does this socket work with HTMA couplings or is it a proprietary fit only?
Answer by: Customer Support on Apr 13, 2025, 8:27 AM
At the 3/8" size, it is interchangeable with HTMA couplings, so you won't be locked into a single brand setup. The flat face design and push-to-connect end also follow ISO 16028, which gives it a broad base of compatibility at that size.
