RF Series quick disconnect couplings, developed by Shanghai Kuaishi Fluid Technology Co., Ltd., are specially engineered for refrigerant data center applications. Adopting a flat-face valve body with dual-seal redundant design, the couplings deliver three core merits: instant connection/disconnection, leak-tight sealing and service-friendly maintenance, setting a new benchmark for reliable connections in refrigerant pipeline systems.
The RF Series adopts a flat-face valve configuration aligned with ISO 16028 standards. Both male and female halves feature machined flat-face valve bodies. Upon connection, the flat sealing surfaces mate flush with each other; upon disconnection, the integral poppet valves close as the two faces separate. This design fundamentally eliminates the risk of fluid leakage, ensuring safe operation of data center equipment.
A secondary sealing layer is added atop the primary seal, forming a redundant sealing architecture. This design prevents seal failure caused by extrusion or nibbling of the primary seal due to residual pressure in the line during connection and disconnection cycles, thereby significantly extending the maintenance-free service intervals of the coupling.
The RF Series Quick Disconnect Couplings from Shanghai Quick-Flow Fluid Technology Co., Ltd. are protected by a national invention patent (China). The core sealing structure has undergone rigorous validation, delivering both technological differentiation and proven reliability—making it a trusted choice for critical connection points in refrigerant systems.
Media & Operating Conditions:
Compatible with mainstream low-GWP refrigerants including R32, R454B, R1234yf, and R515B. Engineered to withstand long-term exposure to high/low-pressure cyclic conditions typical of refrigerant systems.
Equipment & Features:
It is suitable for piping connections in residential air conditioners, commercial VRF (Variable Refrigerant Flow) systems, and industrial water chillers. It also delivers rapid connect/disconnect capability with zero-leakage performance during routine maintenance, troubleshooting, and field servicing operations.
