Product Questions & Answers (3)

Question by: Steve H on Jun 24, 2025, 5:56 PM
got a hose end that’s 7/16-20 JIC, will this adapter mate up to it and what’s on the other side?
Answer by: Customer Support on Jun 26, 2025, 10:27 AM
On one end it has a 7/16-20 male JIC 37 degree flare connection, which matches a female JIC 7/16-20 swivel. The other end is a 1/8-27 male NPTF pipe thread.
Question by: Roger P on Nov 6, 2025, 6:11 PM
i got a line with 1/8-27 npt and need to tie into a 7/16-20 jic, is this the straight adapter for that?
Answer by: Customer Support on Nov 8, 2025, 3:17 PM
Function-wise, it bridges a 1/8-27 male NPT pipe thread to a 7/16-20 male JIC 37 degree flare connection in a straight body. It is part of the Danfoss Eaton 2021 Series Pipe to 37 degree Flare adapters, so it fits that exact thread and end-style changeover.
Question by: Connie R on Oct 26, 2025, 1:07 PM
Is this the right fitting to go from a pipe thread to a JIC flare?
Answer by: Customer Support on Oct 27, 2025, 2:44 PM
Yes, this adapter is designed to connect a 1/8-27 male NPT pipe thread to a 7/16-20 male JIC 37-degree flare.
