Product Questions & Answers (3)

Question by: Peggy S on Jan 4, 2026, 2:26 PM
Will this adapter work for connecting a 3/8 NPT female to a 3/4 JIC male line?
Answer by: Customer Support on Jan 5, 2026, 9:25 PM
Yes, this straight adapter is made to connect a 3/8-18 female NPT to a 3/4-16 male JIC 37 degree flare.
Question by: Bobby C on Jun 19, 2025, 10:40 AM
got a hose end with 3/8-18 female npt on it, will this adapter let me go over to a 3/4-16 male jic flare?
Answer by: Customer Support on Jun 20, 2025, 3:39 PM
Yes. It is a straight steel adapter with a 3/8-18 female NPTF (internal pipe) on one side and a 3/4-16 male JIC 37 degree flare on the other, so it bridges those two connection types.
Question by: Jimmy P on Aug 31, 2025, 6:45 PM
Got a hydraulic line coming off a pump with a 3/8 female NPT port and I need to connect it to a 3/4-16 JIC fitting on the other end, this the right adapter for that?
Answer by: Customer Support on Sep 2, 2025, 6:28 AM
That's what this one's built for. The female end is 3/8-18 NPT and the male end is 3/4-16 JIC with the standard 37-degree flare seat, so it bridges those two thread types in a single straight adapter. No additional fittings needed in between.
