Question by: Gary F on Feb 11, 2026, 7:05 AM
got a port that’s 1-1/16-12 ORB on one side and i need to hook it to a 9/16-18 JIC line. is this the right straight adapter?
Answer by: Customer Support on Feb 12, 2026, 9:45 PM
For that exact thread match, it lines up. One end is a 1-1/16-12 male SAE O-Ring Boss (straight thread O-ring) and the other end is a 9/16-18 male JIC 37 degree flare, in a straight body.
