thread size on this one is 1-5/16-12, that right? just want to make sure before i order a handful of em
Answer by: Customer Support on Jan 23, 2026, 7:55 PM
that's correct. The thread is 1-5/16-12, male SAE O-ring boss, and it meets SAE J514 spec. If you're running a port that matches that configuration, you're good to go.
