got a 3/8 inch tube line I need to terminate with a female JIC end, this the right nut for that?

Question by: Phil H on Feb 7, 2026, 4:14 PM

For a 3/8 inch OD tube going to a JIC 37 degree flare connection, yes, this is the right piece. The J6N is a stainless steel flare nut sized exactly for 0.38 inch tube OD and carries a 9/16-18 thread, which is the standard thread spec for 3/8 inch JIC fittings. It pairs with a mating male JIC 37 degree fitting on the other end.

does this nut fit 3/8 inch tubing or is that the thread size

Question by: Dustin R on Dec 20, 2025, 7:42 AM

The 0.38 inch measurement refers to the outside diameter of the tube it connects to, not the thread size. The mating thread on this nut is 9/16-18, which is the standard JIC thread for 3/8 inch OD tube. So if you're working with 3/8 OD tubing and need a female JIC 37 degree flare connection, this is the right nut.
