Lever Lock Cupla

Product catalog summary

Overview: The document outlines specifications and guidelines for Cuplas, connectors used in low-pressure applications for liquid or gas transport. It includes details on both metal and plastic body Cuplas, covering specifications, materials, and operational guidelines.

Specifications:

Pressure Range: Bulk flow applications range from 0.7 to 1.8 MPa, with working pressure between 0.2 to 0.5 MPa.
Applicable Fluids: Plastic body Cuplas are suitable for water or air only.
Seal Materials: Options include silicone rubber, fluoro rubber, ethylene-propylene rubber, and FEP-covered silicon rubber, each with specific temperature ranges.
Body Materials: Metal bodies are made from aluminum alloy, copper alloy, and stainless steel, while plastic bodies use polypropylene.

Design and Features:

Connection Mechanism: A light lever pull-down securely connects the plug and socket.
Seal Structure: End-face seal structure ensures smooth fluid transport without internal obstructions.
Compliance: Connection dimensions comply with US military specifications MIL-A-A-59326.
Safety Features: Made-to-order metal body products include an additional stopper function for enhanced safety.

Operational Guidelines:

Flow Direction: Fluid can flow in either direction when coupled.
Interchangeability: Sockets and plugs of the same size are interchangeable regardless of end configurations.
Vacuum Suitability: Metal bodies are suitable for vacuum applications up to 53.0 kPa; plastic bodies are not.

Dimensions and Models: Detailed dimensions and model numbers are provided for various Cupla types, including Lever Lock Cupla, Plug types, and Socket types, for both metal and plastic bodies.

Recommendations: Users should read the "Safety Guide" and "Instruction Sheet" before use. Designs and specifications may change for improvement without notice.
