Product Questions & Answers (3)

Question by: Melvin B on Apr 4, 2025, 4:07 PM
trying to hook up a 3/8-18 female pipe port to a JIC line, is this the right adapter?
Answer by: Customer Support on Apr 5, 2025, 9:38 PM
For a straight pipe to flare hookup, it matches that combo: one end is 3/8-18 female NPTF and the other end is 9/16-18 male SAE 37 degree flare (JIC), in steel.
Question by: Lee C on Jan 13, 2026, 3:28 PM
got a hose end that’s 9/16-18 JIC, but the port on the valve is 3/8-18 NPT. is this the right straight adapter to tie those together?
Answer by: Customer Support on Jan 14, 2026, 9:05 PM
It’s meant for exactly that kind of hookup: a 3/8-18 female NPTF internal pipe thread on one side and a 9/16-18 male JIC 37 degree flare on the other, in a straight body.
Question by: Bonnie W on Apr 27, 2025, 5:15 PM
Got a line running NPT fittings on one end and JIC on the other, this the kind of adapter that bridges them two without needing extra pieces in between?
Answer by: Customer Support on Apr 29, 2025, 6:00 AM
Straight through, one piece, no union required. The 3/8-18 female NPT side threads onto your pipe-threaded port, and the 9/16-18 male JIC end with the 37-degree flare seats directly into a matching JIC female. Steel construction keeps it solid under the kind of conditions you'd see in industrial hydraulic connections where both thread standards show up on the same system.
