700R Cupla

Product catalog summary

Specifications:
The 700R Cupla is designed for high-pressure hydraulic applications, supporting pressures up to 68.6 MPa (700 kgf/cm²). It features a two-way shut-off valve structure and is suitable for hydraulic oil.

Models and Dimensions:
The Cupla is available in different models with varying dimensions and thread sizes:

Plug Female Thread: Models 700R-3P and 700R-4P with dimensions L (54, 70 mm), C (18, 22 mm), H(WAF) (24, 27 mm), and T (Rc 3/8, Rc 1/2).
Socket Female Thread: Models 700R-3S and 700R-4S with dimensions L (73, 91 mm), øD (39.5, 50 mm), H(WAF) (22, 27 mm), and T (Rc 3/8, Rc 1/2).

Key Features:

Unique sleeve ring-lock system to handle vibration and impact.
Metal-touch valves without rubber seals for enhanced durability.
Automatic shut-off valves in both socket and plug to prevent fluid spillage.

Test Conditions:
The tests were conducted with hydraulic oil at a temperature of 30˚C ± 5˚C, fluid viscosity of 32 x 10⁻⁶ m²/s, and density of 0.87 x 10³ kg/m³.

Material and Temperature Specifications:

Body Material: Special steel (Nickel-plated).
Seal Material: Nitrile rubber (NBR) for -20˚C to +80˚C, Fluoro rubber (FKM) for -20˚C to +180˚C.

Flow and Pressure Characteristics:

Fluid can flow in either direction when coupled.
Flow rate and pressure loss characteristics are provided for different models.

Interchangeability and Air Admixture:

Different sizes are not interchangeable.
Air admixture varies with usage conditions, with specific values for models 700R-3SP and 700R-4SP.

Torque Specifications:

Max. Tightening Torque: 3/8" - 40 Nm, 1/2" - 85 Nm.

Leakage Rate:

Stand-alone leakage rate for 700R-3SP is 0.05 mL/min at 0.2 MPa, and for 700R-4SP is 0.05 mL/min at 0.3 MPa.

Vacuum Suitability:
The Cupla is suitable for vacuum applications with a pressure of 1.3 Pa.

Safety and Instructions:
Users are advised to read the "Safety Guide" and "Instruction Sheet" before use.
