UQDB Series Quick Coupling
UQDB Series Quick Coupling is a precision-engineered quick-disconnect fluid coupling designed for fast, leak-free connections in high-performance fluid cooling and transfer systems. Made from 316 stainless steel with a robust locking mechanism and excellent sealing, it supports effective flow diameters from DN 1/8 to 1/2, operates up to 20 bar, and withstands temperatures from -40 °C to +125 °C. Its compact, secure connection makes it ideal for data center liquid cooling, industrial thermal control, and automated fluid systems where reliable, tool-free assembly and maintenance are critical.
UQDB Series Quick Coupling is specifically designed for fluid cooling systems in data centers, server rooms, and other critical environments. It features a secure locking mechanism, high durability, and excellent sealing performance to ensure reliable and leak-free operation. Ideal for precise and efficient liquid cooling applications.
Structural features:
-
Quick Connect/Disconnect for Fast System Assembly: The push-to-connect coupling structure locks automatically upon insertion, requiring no additional tools for connection or disconnection. This greatly speeds up installation, maintenance, and component replacement, improving overall operational efficiency.
-
Dry-Break Leak-Free Design for Spill-Free Operation: The flat-face, dry-break design ensures zero dripping during both connection and disconnection. It eliminates fluid loss, contamination risks, and equipment damage, keeping the working environment clean and operation safe.
-
Secure External Locking Structure for Reliable Connection: The coupling relies on an external locking mechanism to hold the connection firmly in place. This design effectively prevents accidental loosening or disconnection caused by vibration, pressure fluctuations, or external forces, ensuring stable performance under demanding conditions.
-
Strong Misalignment Compensation for Easy Installation: The coupling features a high tolerance for installation errors, with a maximum misalignment compensation of ±1.0mm. This strong self-centering capability simplifies assembly, reduces installation errors, and ensures a smooth and secure connection even with minor misalignments.
-
High-Precision Sealing for Consistent Leak-Proof Performance: High-quality seals combined with precision-machined surfaces deliver tight, stable sealing under high pressure. This minimizes leakage risk and maintains consistent system performance even with repeated use.
-
Corrosion-Resistant Construction for Long Durability: Made of high-grade stainless steel with durable plating and premium seals, the couplings offer excellent corrosion resistance. They withstand harsh fluids, moisture, and environmental factors, ensuring long-lasting reliability in industrial and liquid cooling applications.
