Danfoss / Eaton Coupling

Description & Features

Constructed from brass, this straight adapter connects a 1/2 in. NPTF male thread to a 7/8 in. UNF male thread, making it well suited for hydraulic systems requiring a reliable transition between these two common thread standards. As part of the Danfoss / Eaton 338 P Series, it is built to perform above standard SAE pressure ratings, providing additional margin in demanding fluid power applications.

Dura-Kote plating gives this Danfoss / Eaton Coupling strong resistance to corrosion, extending service life in environments where moisture or contaminants are a concern. The 338 P Series encompasses hundreds of fitting configurations, allowing engineers and maintenance personnel to source the correct adapter geometry for a wide range of connection requirements without compromising on quality or performance consistency.

Question by: Cindy H on Jul 22, 2025, 7:55 AM

What kind of pressure rating does this fitting have? I need something that can handle a bit more than the usual.

Answer by: Customer Support on Jul 23, 2025, 6:05 PM

These Danfoss / Eaton couplings are built to exceed standard SAE pressure ratings, so they should offer a bit of extra margin for demanding hydraulic applications.
