Product Questions & Answers

trying to hook up a line that’s 1-11-1/2 male NPT, is this the adapter that’ll get me over to a 1-5/16-12 female ORB?

Function-wise it’s the right style for that changeover. This 2246 Series straight adapter has an external male NPTF pipe thread on one end and an internal female SAE O-ring boss straight thread on the other, sized 1-11-1/2 male NPT to 1-5/16-12 female ORB.
