Specifications Special steel (Nickel-plated) Body material Size (Thread) 210 Cupla For hydraulic pressure up to 20.6 MPa {210 kgf/cm2} Working pressure Valve structure Applicable fluids Working pressure Seal material Working temperature range Working temperature range Seal material Nitrile rubber Fluoro rubber FKM (X-100) -20˚C to +180˚C Available on request Max. Tightening Torque Two-way shut-off Size (Thread) Standard hydraulic Cuplas for general purposes with a working pressure up to 20.6 MPa. Low pressure loss, suitable for hydraulic equipment. • General purpose hydraulic Cuplas with a working pressure of 20.6 MPa {210 kgf/cm2}. • Structure is designed to reduce pressure loss to the lowest, and is best for hydraulic applications that need big flow rates. • Both socket and plug have built-in automatic shut-off valves that prevent fluid outflow when disconnected. Easy to handle. Flow Direction Fluid may flow in either direction from plug or from socket side when coupled. Interchangeability Different sizes are not interchangeable. (mm2) Min. Cross-Sectional Area Model Suitability for Vacuum Socket only Plug only When connected Admixture of Air on Connection Admixture of air may vary depending upon the usage conditions.
