Question by: Tony C on Mar 31, 2025, 9:09 PM
trying to hook up a pipe thread line to an SAE o ring boss port, is that what this 2046 adapter is meant for?
Answer by: Customer Support on Apr 2, 2025, 3:39 PM
Built for pipe to SAE O ring boss connections, the Eaton Aeroquip 2046 Series straight adapter is used when you need to transition from a pipe thread side over to an SAE O ring boss style connection in a straight run.
Question by: Roger W on Oct 18, 2025, 3:51 PM
what industries is this adapter actually built for? seen a lot of generic stuff out there and want something that holds up in real conditions
Answer by: Customer Support on Oct 19, 2025, 6:26 PM
Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this adapter. That covers a pretty wide range of demanding environments, so it's not a shelf-filler built for light duty. The Eaton Aeroquip 2046 Series has a solid track record across those industries specifically because of how it handles the connection between pipe and SAE O-ring boss fittings.
Question by: Travis H on Jul 9, 2025, 12:42 PM
Will this adapter work alright for connecting a pipe to a SAE O-ring boss?
Answer by: Customer Support on Jul 10, 2025, 4:07 PM
That's precisely what this Danfoss / Eaton 2046 series adapter is designed for: connecting a pipe to a SAE O-ring boss.
