Question by: Ross W on Aug 25, 2025, 7:09 AM
trying to hook a 7/8-14 JIC female swivel to a 9/16-18 JIC male, is this the straight reducer i need?
Answer by: Customer Support on Aug 26, 2025, 10:04 AM
Use it when you need to step down between two SAE 37 degree JIC flare sizes. One side is a 7/8-14 female JIC 37 degree flare swivel, and the other side is a 9/16-18 male JIC 37 degree flare, in a straight adapter body.
