got a 3/4 inch tube line running JIC 37 flare connections, need to make sure this nut's gonna thread up right before i order a bunch of em

Answer by: Customer Support on Jul 9, 2025, 8:49 AM

For 3/4 inch OD tube with JIC 37 degree flare connections, this is the correct nut. The mating thread is 1-1/16-12, which is the standard thread size that goes with 3/4 inch JIC flare fittings. SSP machines these from stainless steel, so if you're running a quantity of them on a line, they'll be consistent piece to piece.

trying to swap out a tube nut on a 3/4 tube, is this the right size and thread?

Answer by: Customer Support on Jul 4, 2025, 6:39 PM

It matches 0.75 inch tube OD and it uses a 1-1/16-12 female JIC 37 degree flare nut thread, so it lines up with a 3/4 tube and the corresponding JIC flare connection.
