Flat Face Couplings Redesigned

By Mike Brezonick15 January 2018

Eaton said it has redesigned its FF-series quick disconnect couplings to help mobile machine manufacturers meet market demand for high pressure and high impulse pressure solutions. Suitable for a wide variety of industries, applications include attachments for agricultural machinery, wheel loaders, excavators, bulldozers, commercial trailers, rail maintenance equipment and forestry equipment.

The renewed flat faced quick-disconnect couplings help reduce pressure drops and decrease energy loss, resulting in lower fuel and energy consumption. High flow rates, even on smaller sizes, offer more design flexibility as smaller size hoses can be used.

Eaton’s FF quick-disconnect couplings exceed ISO 16028 standards for working pressures by achieving 5800 psi (400 bar) for static, steady or non-pulsed applications, beyond the 3600 psi (250 bar) standard. The couplings assert a burst pressure of 20,000 psi (1400 bar) and 5000 psi (350 bar) for ISO pressure rating for dynamic applications with moderate hydraulic shocks, again exceeding the 3600 psi defined in the standard.

The redesign also includes Guardian Seal plating that Eaton said offers up to three times more corrosion resistance. Color-coded ends make it easy to connect the couplings without mistakes, even in the field, the company said.
