Question by: Pete T on Mar 28, 2026, 10:01 AM
Hey, I'm just trying to make sure this is gonna fit right... my current fitting is .5625, and this says it's .5625 on one end. Just wanna confirm?
Answer by: Customer Support on Mar 30, 2026, 6:27 AM
That's correct, the ORS end of this adapter is indeed 0.5625 inches. The other end, the SAE ORB, is 0.5 inches. So as long as your mating parts match those sizes and thread types, you should be good to go.
