Danfoss / Eaton Coupling

Description & Features

Constructed from brass, this straight adapter connects a 1/16 in. NPTF male thread to a 1/16 in. female hose, pipe, or tube end, making it well suited for instrumentation, hydraulic, and pneumatic system connections. The fitting carries Dura-Kote plating for corrosion resistance and is rated for operating pressures above SAE standards, with a minimum working temperature of -65°F. The 3/8 in. hex provides a standard wrench engagement for installation.

The Danfoss / Eaton Coupling is part of a broad SelfAlign series offering design flexibility across hundreds of styles and configurations. Its brass construction and protective plating make it a reliable choice for demanding fluid power and instrumentation environments where corrosion resistance and pressure performance are priorities.

Will this work for hooking up some gauges to an air compressor?

Answer by: Customer Support on Mar 24, 2026, 8:58 PM

For instrumentation, hydraulic, and pneumatic systems, this coupling is suitable. The 1/16 in. NPTF male to 1/16 in. female connection should work for standard gauge setups.
