Danfoss / Eaton Coupling

Description & Features

Constructed from brass, this straight adapter connects a 3/8 in. NPTF female thread to a 3/8 in. hose, pipe, or tube female end, making it well suited for instrumentation, hydraulic, and pneumatic system connections. The Danfoss / Eaton Coupling features Dura-Kote plating for corrosion resistance and is rated for operating pressures above SAE standards, providing reliable performance across a wide range of demanding applications.

A minimum working temperature of -65°F supports use in cold-environment service conditions. The 0.813 in. hex size allows for standard wrench installation, and the straight adapter configuration keeps routing simple where a direct inline connection is required. With hundreds of available styles in the broader product line, compatible configurations are accessible for varied system requirements.
