trying to swap out an old 90 degree swivel, are both ends on this one 1 inch male and what fittings are they
Answer by: Customer Support on Dec 22, 2025, 4:25 PM
It is a 90 degree swivel joint with two 1 inch male ends. One side is a 1 inch SAE 37 degree (JIC) male, and the other side is a 1 inch O Ring Boss (ORB) male.
Question by: Hank G on May 9, 2025, 2:05 PM
Got a line on some mobile equipment that keeps binding up at a 90-degree connection point. Would this swivel joint take care of that, and what size fittings are we talking about?
Answer by: Customer Support on May 11, 2025, 12:58 PM
For a 90-degree connection that needs rotational freedom, this one covers it. One end is a 1-inch SAE 37 male (JIC), and the other is a 1-inch O-Ring Boss male. Both are 1-inch swivel size, so as long as your lines match up to those thread types and sizes, it should sort out that binding issue by letting the joint rotate instead of stressing the line.
