Question by: Hugh B on Sep 14, 2025, 2:57 PM
i’ve got a hose end that’s 1-1/16-12 JIC, what’s on the other side of this adapter?
Answer by: Customer Support on Sep 15, 2025, 9:32 PM
On the other end you get a 3/4-14 male NPTF pipe thread, so it bridges between a 1-1/16-12 male JIC 37 degree flare side and a 3/4-14 male NPTF side in a straight adapter.
