HSP Couplers Series for Oil Pressure
HSP COUPLERS FOR OIL PRESSURE –SOCKETS / PLUGS– –HEAT RESISTANT 180°C TYPE–
Sockets Plugs Connect by matching the hole diameter with the plug diameter Suitable
E Please note that the HSP coupler series for Oil Pressure cannot be connected to different sizes. For male screw joint YHS (With valve)
HSP Couplers for Oil Pressure –Sockets/Plugs– ■ Characteristics • The coupler body is made of Heat–treated special steel. • It demonstrates its power in impact resistance.
※ Plug connector (Hole diameter V)
Rc （ PT ）
• The valve structure minimizes pressure loss, making it particularly suitable for hydraulic applications requiring high flow rates. • Both the socket and plug are equipped with automatic opening/closing valves to prevent fluid leakage during separation.

Order
• Tighten the plug under the maximum tightening torque. • Use within the allowable temperature range. • Do not use the mold couplers for any other purposes than water cooling. • Before installing or removing the socket, make sure to check that the pressure has come down to zero and the temperature of the fluid (oil) to below 30°C for avoiding any accidents that may result from splashed hot fluid.
