Question by: Shawn Y on Jul 13, 2025, 6:37 AM
trying to hook a #8 female JIC line up to a #10 male JIC port, is this the right straight adapter?
Answer by: Customer Support on Jul 14, 2025, 8:38 AM
For that mix, yes. It’s a straight 37° JIC flare union adapter with a 3/4-16 female JIC on one side and a 7/8-14 male JIC on the other.

Question by: Troy S on Nov 10, 2025, 3:30 PM
got a 3/4-16 female JIC end on my hydraulic line and need to step up to a 7/8-14 male JIC connection. this the right adapter for that?
Answer by: Customer Support on Nov 12, 2025, 8:56 AM
That's what this one's built for. The female end threads onto a 3/4-16 JIC fitting and the male end connects to a 7/8-14 JIC port, both running that standard 37-degree flare seat. No thread sealant needed either, so you're not adding extra steps to the job. Both sides seal on the flare itself, which is how JIC fittings are supposed to work.
