So, this thing'll go from a 7/8-14 to a 7/16-20 fitting, right? Just makin' sure before I order.

That's correct. This adapter transitions from a 7/8-14 male JIC 37-degree flare to a 7/16-20 male JIC 37-degree flare.

got two JIC lines, one’s a #10 and the other’s a #4. is this the straight piece that’ll join em up?

Built for tying two different JIC 37 degree flare sizes together, it goes from 7/8-14 male JIC on one side to 7/16-20 male JIC on the other in a straight union.
Question by: Stan H on Oct 8, 2025, 12:55 PM
got a #10 JIC fitting on one end and need to step down to a #4 JIC on the other -- will this straight adapter handle that?
Answer by: Customer Support on Oct 9, 2025, 9:44 PM
That's what this one's built for. One end is 7/8-14 male JIC 37 degree flare, which is your #10 size, and the other end is 7/16-20 male JIC 37 degree flare, your #4 size. Both sides use the same 37 degree flare seating, so the connection stays clean and tight without needing any thread sealant. Straight configuration, no offset, just a direct male-to-male union between those two JIC sizes.
