Question by: Connie P on Aug 16, 2025, 9:42 AM
got a hose end that’s 1-11-1/2 female swivel and I need to land it on an ORB port, is this the right adapter?
Answer by: Customer Support on Aug 18, 2025, 7:43 AM
For that kind of hookup, this adapter matches a 1-11-1/2 female NPSM swivel on one end and a 1-5/16-12 male SAE O-Ring Boss (ORB) straight thread on the other, in a straight configuration.
Question by: Lyle A on Mar 7, 2026, 8:49 AM
got a 1-11-1/2 female npt swivel on one side and need to go to a 1-5/16-12 male SAE o-ring boss, is that what this adapter is?
Answer by: Customer Support on Mar 9, 2026, 6:52 AM
For connecting pipe thread to an SAE straight thread O-ring boss port, this 2066 Series straight adapter matches those ends: a 1-11-1/2 female NPT swivel on one side and a 1-5/16-12 male SAE O-ring boss (straight thread O-ring) on the other.
