UQDB Series Universal Quick Disconnect Blindmate Couplings

Parker UQDB Series Quick Disconnect Couplings are high-performance liquid cooling connectors for data centers, servers, supercomputers, and other high-performance computing (HPC) applications. Developed in collaboration with OCP (Open Compute Project) and approved by the NVIDIA Partner Network (NPN), UQDB quick disconnects provide a reliable connection solution for modern data center liquid cooling systems.

Designed for interoperability, Parker UQDB plugs and sockets are interchangeable with other OCP-approved UQDB quick disconnect couplings. The plug features a floating connection element that accommodates up to 1 mm of axial misalignment, helping simplify installation and connection within demanding liquid cooling architectures.

Parker UQDB stainless steel quick disconnect couplings are available in multiple sizes and port configurations for integration with rack manifolds, flexible cooling hoses, servers, IT equipment, and liquid-cooled data center infrastructure. Their durable stainless steel construction and EPDM seals are designed to support reliable operation in advanced thermal management and electronics cooling applications.

To help protect sensitive electronics and maintain cooling system cleanliness, Parker UQDB Series couplings are manufactured, assembled, and tested in a controlled clean-room environment. Final assemblies undergo helium leak testing for quality assurance and dependable leak-resistant performance.
