Question by: Gary L on Jul 28, 2025, 4:02 PM
got a hose end that’s 9/16-18 JIC, and the port on the block is 3/8-18 NPT. is this the straight adapter that ties those two together?
Answer by: Customer Support on Jul 30, 2025, 9:58 AM
For hooking those two standards together, it’s a straight brass adapter with a 3/8-18 male NPT end on one side and a 9/16-18 male JIC 37 degree flare on the other.
