Question by: Dustin P on Jan 21, 2026, 7:54 AM
what's the port size and thread type on this coupling, and will it hook up to standard hydraulic wet line fittings on a dump truck?
Answer by: Customer Support on Jan 23, 2026, 6:18 AM
Port size on this one is 3/8 inch, and the threaded end runs NPTF, which is the tapered pipe thread you'll find on most standard wet line setups for dump and refuse trucks. It's a female half with a thread-to-connect style, so it mates the way you'd expect without needing any special tools or adapters beyond what you'd normally have on hand.
