Product Questions & Answers

Just want to make sure, this adapter will let me hook up a hose with a 7/8-14 SAE O-ring fitting to a 1/2-14 NPT pipe, right?
Question by: Gary B on Oct 12, 2025, 9:59 PM
That's correct. This Eaton Aeroquip adapter is specifically designed to connect a 1/2-14 male NPT to a 7/8-14 female SAE O-ring boss, providing a reliable seal.

Got a port on my hydraulic manifold that's 7/8-14 SAE O-ring boss and I need to run 1/2 NPT pipe thread into it. This the right adapter for that?
Question by: Chad P on Apr 7, 2025, 9:08 AM
That's exactly the configuration this adapter handles. The male end is 1/2-14 NPT and the female end accepts a 7/8-14 SAE O-ring boss connection, so it bridges those two thread types in a straight configuration. The O-ring boss side gives you a clean, reliable seal at the port without relying on thread taper alone, which is a real advantage in pressurized hydraulic systems. It's from Eaton Aeroquip's 2246 series and the catalog number is C1BD40 if you need to cross-reference it for procurement.
