Question by: Hugh M on Jul 1, 2025, 9:17 PM
trying to hook a 3/8-18 NPT port up to a 1/4 inch JIC line, is this the right adapter?
Answer by: Customer Support on Jul 3, 2025, 8:35 AM
For that kind of changeover, it matches up as 3/8-18 male NPT on one end and 7/16-20 male JIC 37 degree flare on the other, and it’s sized for 0.25 inch tube O.D. on the JIC side.
Question by: Danny R on Dec 27, 2025, 9:22 PM
Will this adapter hold up if its exposed to some harsh chemicals and stuff?
Answer by: Customer Support on Dec 29, 2025, 1:07 PM
Being made from 316 stainless steel, this adapter offers excellent corrosion resistance, making it suitable for use in harsh conditions.
Question by: Rhonda G on Oct 19, 2025, 9:02 AM
got a line running 3/8 NPT male and need to tie into a JIC 37 flare fitting on the other end, this straight adapter do the trick?
Answer by: Customer Support on Oct 21, 2025, 6:24 AM
That's what this one's built for. One end is 3/8-18 male NPT and the other is 7/16-20 male JIC 37-degree flare, straight configuration. Both ends are male, so you'll want female counterparts on each side of your connection. No thread sealant is required on this adapter, which cuts down on prep time during install.
