Product Description

The UQDB Series Blind-Mate Quick Connector is a precision-engineered fluid connection solution, purpose-built for automated, high-density liquid cooling systems. Manufactured by Hoonsun, this blind-mate coupling features a 316L stainless steel body and advanced sealing technology, enabling reliable, tool-free connections in blind-mating environments.

Available in DN03, DN05, DN07, and DN10 sizes, it supports a rated working pressure of 20 bar (burst pressure 80 bar) and operates across a wide temperature range of -40°C to +120°C. The EPDM seal ensures compatibility with deionized water, glycol solutions, and common industrial fluids. The self-aligning design allows for fast, error-proof connections without visual alignment, making it ideal for high-volume, automated assembly processes.

Applications

Data Center & HPC Liquid Cooling: High-density server rack liquid cooling connections
EV Charging Piles & Thermal Management: Automated blind-mate connections for electric vehicle systems
Industrial Laser Equipment: Precision cooling for high-power industrial lasers
Medical Equipment: MRI machines, diagnostic devices, and precision instrument cooling
Photovoltaic Inverters: Outdoor solar and wind power electronic cooling systems
Automated Assembly & Test Benches: Blind-mate connections for automated fluid transfer systems
High-Density Electronic Systems: Compact, error-proof fluid connections in limited-access environments

Installation Process

Preparation: Ensure the connector and mating components are clean, free of debris, and undamaged. Depressurize the fluid system before installation.
Blind-Mate Connection: The self-aligning design automatically guides the plug into the socket as the components are brought together. No visual alignment or manual manipulation is required.
Verification: Once the components are fully mated, the connector will lock into place. Perform a pressure test to confirm no leaks before bringing the system online.
Disconnection: Simply separate the components; the connector will automatically disengage and seal to prevent fluid loss. No tools are required.

⚠️ Safety Note: Never force the connection. The self-aligning design should guide the plug into the socket smoothly. Always depressurize the system before disconnection.

FAQ

What is the key advantage of the UQDB series over standard quick connectors?

The UQDB series features a blind-mate, self-aligning design, allowing for fast, error-proof connections without visual alignment. This makes it ideal for high-density, automated assembly environments.

Are different sealing materials available?

Standard EPDM seals are suitable for water and glycol solutions. Custom sealing materials (such as FKM for high-temperature or chemically aggressive fluids) are available upon request.

What fluids can the UQDB connectors handle?

They are compatible with most common liquid cooling media, including deionized water, glycol mixtures, industrial oils, and fluorinated fluids.

What is the maximum working pressure and temperature?

Rated working pressure is 20 bar (burst pressure 80 bar), with an operating temperature range of -40°C to 120°C.

Can these connectors be used outdoors or in harsh environments?

Absolutely. The 316L stainless steel construction provides excellent resistance to corrosion, salt spray, and extreme temperatures, making them suitable for outdoor and industrial applications.

Do I need tools to install or remove them?

No. The blind-mate design allows for tool-free connection and disconnection, simplifying installation and maintenance.

Is customization available for specific applications?

Yes. We offer custom thread sizes, connection types, and sealing materials to meet unique system requirements.

What is the typical service life?

With proper installation and maintenance, the 316L stainless steel body and high-quality seals ensure a long service life, even in continuous operation.
