got an older utility vehicle that needs a new htma style coupler. trying to figure out if these threads are 1/4 inch NPT
Answer by: Customer Support on Jun 8, 2025, 6:34 AM
Matching your exact thread dimensions is important for a proper seal. The threads on this female half are exactly 1/4-14 NPT and the body interchanges directly with standard 3/8-inch size HTMA couplings.
Question by: Ray H on Mar 8, 2026, 2:56 PM
Will this quick disconnect work with other HTMA couplings? I've got a few different ones on my equipment.
Answer by: Customer Support on Mar 10, 2026, 12:35 PM
It does indeed have a globally accepted interface meeting HTMA requirements, specifically in the 3/8” size. So, yes, it should be interchangeable with other HTMA couplings of that size.
Question by: Eddie H on Jul 15, 2025, 7:10 AM
trying to match up couplers on a hydraulic tool line. is this the female half in the FF series, and what size is it?
Answer by: Customer Support on Jul 16, 2025, 12:43 PM
For fit and interchange, you are looking at the FF Series female half with a -08 coupling size. It uses the ISO 16028 flush face interface and also meets HTMA requirements, and it is noted as interchangeable with HTMA couplings in the 3/8 inch size.
