Question by: Rusty M on Aug 25, 2025, 9:00 PM
trying to replace an adapter i pulled off a hose, does this one match 1/2-14 female npt on one side and 3/4-16 male o-ring boss on the other?
Answer by: Customer Support on Aug 27, 2025, 6:21 AM
The thread callouts on this adapter are 1/2-14 female NPTF on one end and 3/4-16 male SAE O-Ring Boss (ORB) on the other. It is a straight steel pipe to straight thread O-ring adapter, so those two thread sizes and end types are what it mates to.
Question by: Phil M on Mar 1, 2026, 7:01 PM
got a port thats 1/2-14 female npt on the manifold, will this adapter get me over to a 3/4-16 male o-ring boss without any funny business
Answer by: Customer Support on Mar 3, 2026, 3:05 PM
Function-wise, it bridges a 1/2-14 female NPT connection over to a 3/4-16 male SAE O-Ring Boss straight thread connection, and it does it in a straight adapter style.
Question by: Phil M on Apr 14, 2025, 5:45 PM
Will this adapter work for connecting a hydraulic line to a port on a manifold? I'm needing to go from a female pipe thread to a male o-ring boss.
Answer by: Customer Support on Apr 16, 2025, 6:44 AM
This adapter is designed to connect a 1/2-14 female NPT (National Pipe Taper) to a 3/4-16 male SAE O-ring Boss. It's a straight adapter, so it'll make a direct connection between the two.
