DANFOSS / EATON Cplng FF SERIES

Description & Features

The Danfoss / Eaton Hansen FF Series Quick Disconnect Couplings Socket is engineered for high-performance hydraulic and fluid transfer systems. These couplings are indispensable for construction equipment agricultural machinery utility vehicles on-highway vehicles and stationary in-plant hydraulics due to their robust features and compliance with industry standards.

Manufactured from durable carbon steel this component ensures reliable connections with a push-to-connect end type and a flat face internal connection. The sleeve lock safety mechanism enhances secure coupling during demanding applications.

With ISO 16028 certification and compliance with the European Pressure Equipment Directive (PED) 97/23 EC Article 3.3 REACH and RoHS standards you can trust in their quality and sustainability. The maximum working temperature for these couplings goes as low as -13F ensuring performance in extreme conditions.

These couplings exceed ISO 16028 operating pressures and require no special tools for installation simplifying the setup process in various hydraulic systems.

Question by: Frank M on Feb 22, 2026, 8:34 PM
What’s the lowest temp this coupling can handle? Gotta make sure it can take the cold out here.
Answer by: Customer Support on Feb 24, 2026, 3:03 PM
These Danfoss/Eaton couplings are rated down to -13 degrees Fahrenheit, so they should hold up well in cold conditions.
Question by: Phil J on Apr 1, 2025, 3:09 PM
got a flat-face setup on a skid steer, is this the female half with the sleeve lock?
Answer by: Customer Support on Apr 2, 2025, 5:53 PM
For a flat-face quick disconnect setup, this is the female half and it uses a sleeve lock safety mechanism to help keep the connection from backing off during use.
