Flat-face male coupling with pressure eliminator, G 3/4", size 4, 400 bar, zinc-plated steel

For hydraulic lines with a G 3/4" female thread that are rejoined under static pressure: this size 4 male half carries a pressure eliminator and holds 400 bar.

Advantages

• The pressure eliminator allows connection while static pressure remains on the male side, for example after sunlight has heated a disconnected component.
• The design is fully compatible with standard flat-face couplings.
• Zinc-plated steel with an NBR seal covers a temperature range of -30 to +100 °C.
• Working pressure of 400 bar at a nominal bore of 19 mm in size 4.
• The flat coupling face can be wiped clean before connecting, so no dirt enters the hydraulic system.

Applications

The intended use covers hydraulic hose lines that are disconnected and rejoined in service. A working pressure of 400 bar and a temperature range of -30 to +100 °C set the limits.
