Question by: Glen J on Nov 24, 2025, 6:58 PM
porting on this unit, is it SAE ORB or something else? got a 1-7/8" -12UN fitting on my existing line and want to make sure it drops right in without adapters
Answer by: Customer Support on Nov 26, 2025, 2:08 PM
Main ports are 1-7/8" -12UN #24 SAE ORB, so that's a direct match for what you've got. The top ports are 1/4" NPTF if you need those for anything. No adapters required on the main connection side.
