Question by: Ray B on Jan 20, 2026, 8:33 PM
got a hose end that’s 9/16-18 JIC, and the port on my valve is 1/2-20 ORB. is this the right straight adapter to tie those together?
Answer by: Customer Support on Jan 22, 2026, 5:34 PM
It bridges those two thread styles in a straight body, with a 1/2-20 male SAE O-Ring Boss on one end and a 9/16-18 male JIC 37 degree flare on the other.
