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.

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.
