What size threads does this thing have? I'm trying to replace an old fitting.
Answer by: Customer Support on Mar 31, 2026, 6:24 PM
It's got a 3/8-24 Male SAE O-Ring Boss thread and a 1/4-18 Female NPSM thread, meeting SAE J514 and SAE J476 standards, respectively. Should be just the ticket for a standard hydraulic setup.
