Danfoss / Eaton Coupling

Description & Features

Constructed from brass with Dura-Kote plating for corrosion resistance, this straight adapter connects a 1/8 in. NPTF female thread to a 1/8 in. hose, pipe, or tube female end. The Danfoss / Eaton Coupling is well-suited for instrumentation, hydraulic, and pneumatic system connections where reliable sealing and durability are required across a wide temperature range, rated down to -65°F.

Operating pressures exceed SAE standards, making this fitting appropriate for demanding fluid power applications. The 7/16 in. hex on the line end allows for standard wrench installation, and the straight adapter configuration supports compact, in-line routing without additional bends or transitions.
