UQD Connector | Universal Quick Disconnect Coupling

In liquid cooling applications, leakage is a critical concern, with connectors being the most common points of failure. The Guchen UQD liquid cooling connector addresses these challenges, providing a leak-free, high-performance solution that supports reliable and maintainable data center operation. Its advantages include high flow rate, low pressure drop, hot-swappable capability, and robust durability under frequent connection cycles.
The Universal Quick Disconnect Coupling standard is an open, anti-splash quick-release coupling specifically designed for data center liquid cooling. Initiated by Intel and developed under the OCP (Open Compute Project) framework, the UQD connector comes in four sizes—02, 04, 06, and 08 - and features well-defined physical and performance characteristics. Critical specifications such as flow rate rating, temperature rating, pressure rating, burst pressure, liquid loss upon disconnection, and flow coefficient ensure that the connectors meet the rigorous demands of modern data center cooling systems.
