  • UQD Liquid Cooling Quick Connector

Short Description:

UQD is a standard quick-disconnect liquid cooling connector for OCP, featuring a bidirectional self-sealing valve structure and EPDM rubber sealing rings that are resistant to high and low temperatures as well as coolant. It ensures zero leakage during plug and unplug operations, single-handed quick plug and blind installation, and high flow with low pressure drop. It has core advantages such as high pressure resistance, long plug and unplug life, and compatibility with multiple brands for interconnection. It is mainly applied in AI servers, high-density data centers, HPC supercomputers, energy storage, and direct/indirect cooling liquid cooling systems for high-power power electronics. It serves as a standardized core connection component for interconnecting cold plates and rack water distributors.

What Is UQD

UQD stands for Universal Quick Disconnect, an OCP open-standard liquid cooling quick coupling specially designed for AI servers, data centers and high-power electronic liquid cooling systems.

It adopts double-sided self-sealing valve structure with high-performance rubber seals, realizing leak-free connection and disconnection, one-hand quick plug and blind mating. With low pressure drop, high flow rate and long service life, UQD supports cross-brand interoperability. It is widely used in cold plate connection, manifold pipeline matching and direct liquid cooling deployment for high-density computing, HPC and energy storage equipment.

Key Features Of UQD

OCP Open Standard
Universal interchangeability among different brands, unified specification for data center liquid cooling.

Zero Leakage & Self-sealing
Built-in double shut-off valve, drip-free connect/disconnect, minimal residual liquid.

One-hand Quick Connection
Easy plug-and-play design, supports blind mating and floating assembly.

 High Flow & Low Pressure Drop
Optimized internal flow channel, reduces flow resistance and cooling energy consumption.

 Premium Sealing Performance
Adopts EPDM/FKM/HNBR sealing materials, resistant to coolant, high and low temperature aging.

High Pressure & Long Service Life
Stainless steel main body, high working pressure, excellent corrosion resistance and plug cycle life.

 Color Coding Design
Red for liquid supply, blue for liquid return, avoid wrong connection.

How UQD Work

UQD is a self-sealing quick disconnect coupling for liquid cooling systems.

When disconnected

Internal spring-loaded check valves on both plug and socket automatically close, locking the liquid inside the pipeline to prevent leakage.

When plugging in

The two valve heads push each other open, the internal flow channel connects smoothly, and coolant circulates normally.

After fully locked

The snap ring fixes the connection tightly; it supports vibration resistance and stable liquid transmission.

When unplugging

Unlock the buckle first, the internal valves reset and close instantly, achieving drip-free disconnection.

Advantages Of UQD

 Open standard & universal compatibility
Complies with OCP standard, cross-brand interchangeable, easy for standardized deployment.

Drip-free connection & disconnection
Dual self-sealing valve design, almost no residual liquid when mating or disconnecting, safer for server and circuit devices.

Easy & fast installation
One-hand operation, plug-and-play, supports blind-mate and floating alignment, saves assembly and maintenance time.

High flow with low pressure drop
Optimized inner flow path reduces flow resistance, improves cooling efficiency and lowers overall energy consumption.

Excellent durability & corrosion resistance
Stainless steel body plus high-performance rubber seals, resistant to coolant, aging and temperature change, long service cycle.

High system reliability
Locking structure prevents loose off; color coding avoids supply/return pipeline misconnection.

 Wide application adaptability
Suitable for AI servers, data centers, HPC, energy storage and high-power electronic liquid cooling systems.
