The Danfoss / Eaton Hansen FF Series Quick Disconnect Couplings Socket is designed for applications in hydraulic and fluid transfer systems. Specifically crafted to adhere to ISO 16028 dimensions, it ensures compatibility with a range of hydraulic machinery in various sectors including construction, agriculture, utility vehicles, on-highway vehicles, and in-plant fluid transfer systems.
This component features a globally accepted interface meeting HTMA standards. The dual flush face valves are designed to minimize fluid loss and air inclusion, offering an efficient and clean connection. The sleeve lock mechanism provides an additional layer of safety by preventing accidental disconnections.
Engineered for quick and easy Push-to-Connect latching, this coupling ensures seamless connectivity. The seal material, made of NBR+AU, provides robust performance under varying temperature conditions, ranging from -13deg;F to +212deg;F.
With a torque rating of 31.5 lb/ft and a two-way valve type, this hydraulic tool quick disconnect coupling is reliable and effective. Its end sizes of 0.5 and 0.75 coupled with SAE threads assure precision and durability in demanding environments.

got a skid steer with a busted female coupler on the hydraulic line, threads are -8 SAE and the coupling size is -06. this the right replacement?
Answer by: Customer Support on Mar 10, 2026, 8:19 AM
For a -06 coupling with -8 SAE female threads, yes, that lines up exactly with what this part is spec'd for. The female half connects via Push-to-Connect latching on the coupling side and picks up the -8 SAE thread on the port end. Sleeve lock keeps it from backing out on its own during operation, which matters on a skid steer where things move around a lot. Seal material is NBR plus polyurethane, rated from -13°F up to 212°F, so standard outdoor working conditions aren't going to be a problem.

got a hydraulic tool that uses the 3/8 HTMA style couplers, is this female half gonna swap in without a bunch of fuss?
Answer by: Customer Support on Nov 26, 2025, 6:55 AM
For HTMA style hookups in the 3/8 size, it is meant to interchange and it follows ISO 16028 dimensions. It is the female socket half in the FF Series, with a -06 coupling size and a sleeve lock to help prevent an accidental pull-off.
Question by: Norm W on May 16, 2025, 9:08 AM
Will this fitting work with standard hydraulic fluid, or do I need something special?
Answer by: Customer Support on May 18, 2025, 6:09 AM
Designed with NBR+AU seals, this quick disconnect is good to go with standard hydraulic fluids within a temperature range of -13°F to +212°F.
