Product Questions & Answers (3)

Question by: Peggy B on Jun 12, 2025, 7:21 AM
Been trying to find an adapter that'll connect my 3/4 NPT male port over to a 1-1/16-12 JIC 37 degree flare fitting without having to mess with thread tape or sealant. This gonna do the trick?
Answer by: Customer Support on Jun 13, 2025, 1:04 PM
For a straight male NPT to male JIC 37 degree flare connection, that's exactly what this adapter handles. The 3/4-14 NPT end and the 1-1/16-12 JIC 37 degree flare end mate up in a single straight fitting, and the JIC flare seat creates its own seal without needing tape or pipe dope. It's rated for light to medium pressure applications, so as long as your system falls in that range you should be good to go.
Question by: Gene C on Aug 13, 2025, 7:07 PM
What kind of pressure is this adapter good for?
Answer by: Customer Support on Aug 15, 2025, 6:50 AM
It's designed for light to medium pressure applications, so it should hold up well in those setups.
Question by: Vince W on Apr 7, 2025, 4:01 PM
trying to hook a 3/4-14 npt port up to a 12 jic line, is this the straight adapter for that?
Answer by: Customer Support on Apr 9, 2025, 9:34 AM
For tying those two standards together, this adapter matches a 3/4-14 male NPT on one end and a 1-1/16-12 male JIC 37 degree flare on the other, in a straight body.
