Question by: Roy S on Apr 14, 2025, 4:09 PM
got a port that’s 2-1/2-12 SAE o-ring boss on one side and i need to go to a 1-11-1/2 female npsm, is that what this fitting is?

Built for that exact thread change, it has a male SAE O-ring boss on the B1 end (2-1/2-12 per SAE J514) and a female NPSM on the B2 end (1-11-1/2 per SAE J476).
