got a 1/4 inch tube line I need to terminate with a JIC connection, this nut gonna work for that?

Answer by: Customer Support on Jan 24, 2026, 6:53 AM

For a 1/4 inch OD tube with a JIC 37 degree flare connection, yes, that is exactly what this fitting is built for. The mating thread is 7/16-20, which is the standard thread size paired with 1/4 inch tube on JIC flare assemblies. Stainless steel construction makes it a solid choice where corrosion resistance matters.

For a 1/4 inch tube OD using a female JIC 37 degree flare nut, this part matches that connection style. It is a stainless steel flare nut and the tube OD called out for it is 0.25 inch.

Question by: Harold S on Nov 20, 2025, 9:01 AM

fitting's got a 7/16-20 thread on it, right? just want to make sure before i order a handful of these for the shop

Answer by: Customer Support on Nov 21, 2025, 9:57 AM

Correct, the mating thread on this nut is 7/16-20, which is the standard thread size that goes with a 1/4 inch OD tube in a JIC 37 degree flare connection. That pairing is pretty consistent across JIC fittings at this tube size, so if your existing hardware follows that spec, you should be in good shape.
