Eaton launches redesigned hydraulic coupling


Eaton’s latest hydraulic coupling has been redesigned to offer increased reliability under high pressure conditions.

The Flat Face series (FF) quick disconnect coupling is designed to be an appropriate attachment for a wide variety of applications, including agricultural machinery, wheel loaders, excavators, bull dozers, commercial vehicle trailers, rail maintenance equipment and forestry vehicles.

Flow rate has been increased by 25% on the new coupling, and pressure rate is now up to 400 bar. The quick-disconnect couplings exceed ISO 16028 standards for working pressures by achieving 400 bar, for static, steady or non-pulsed applications, instead of 250 bar from the standard.

As a result, it is able to reduce pressure drops and unwanted decreases in energy losses, maximizing machine performance in high-pressure environments.

“Market needs are moving toward more compact solutions requiring higher working pressures,” said Ron Molijn, manager for product sales at Eaton. “Designers are working on making equipment more compact as ISO 16028 standard working pressures of 250 bar is no longer sufficient. In mobile applications, the high pressure and the associated high pulse pressure are key for more robust, dynamic applications.”

The FF boasts a burst pressure of 1,400 bar and 350 bar for an ISO pressure rating for dynamic applications with moderate hydraulic shocks, which again exceeds the 250 bar defined in the standard. The redesign includes ‘green’ Guardian Seal plating that offers up to three times more corrosion resistance.

Tests revealed 720 hours minimum salt spray test corrosion resistance, which helps to provide higher corrosion protection to reduce maintenance and downtime, and improve productivity and reliability in harsh environments.
