Product Questions & Answers (2)

Question by: Danny T on Jul 27, 2025, 1:46 PM
So, this fitting, it's got a male NPT on one side and a male JIC flare on the other? Just want to make sure I'm reading it right.
Answer by: Customer Support on Jul 29, 2025, 6:39 AM
That's correct. It adapts from a 1/8-27 Male NPT to a 1/2-20 Male JIC 37-degree flare.
Question by: Lyle W on Sep 22, 2025, 3:10 PM
got a hose with a 1/8-27 npt port on one side and need to tie into a 1/2-20 jic line on the other. is this the right straight adapter?
Answer by: Customer Support on Sep 23, 2025, 5:04 PM
Matches that setup. One end is 1/8-27 male NPT and the other end is 1/2-20 male JIC with a 37 degree flare, and it’s a straight adapter in the Eaton Aeroquip 2021 series.
