MQD Series Multi Quick Disconnect Couplings

Parker MQD Series Quick Disconnect Couplings are high-performance liquid cooling connectors developed in collaboration with NVIDIA to meet the evolving demands of data center liquid cooling. MQD plugs and sockets are designed for interoperability and are interchangeable with other approved MQD manufacturers.

Manufactured from high-quality stainless steel, Parker MQD quick disconnects are available in multiple sizes and port configurations for integration with servers, IT equipment, inner manifolds, and high-performance computing systems. Their compact design makes them ideal for in-tray liquid cooling connections where reliable coolant flow and efficient use of space are critical.

Parker MQD Series couplings feature a flush-face, non-spill valve design that helps minimize fluid loss and protect sensitive electronic components. Products are assembled and tested in a clean-room environment to help reduce contamination, with final assemblies undergoing helium leak testing for dependable quality and performance.
