Installation Process
1
Preparation: Ensure the connector and mating part are clean and free of debris.
2
Alignment: Align the plug and socket along the axis.
3
Blind-Mate Connection: Push the plug into the socket until you hear/feel a click, confirming full engagement.
4
Leak Test: After connection, perform a pressure test to verify zero leakage.
5
Disconnection: Simply pull the plug out of the socket (no tools required) for maintenance or replacement.
⚠️ Note: Ensure the system is depressurized before disconnection to prevent fluid spray.

Frequently Asked Questions
What is a blind-mate quick connector?

It is a fluid coupling designed for "blind" connections (without visual alignment) in liquid cooling systems, enabling fast, reliable plug-and-play installation.

What materials are available?

We offer two main options: 316L Stainless Steel for excellent corrosion resistance in harsh environments, and Aluminum Alloy for a lightweight, high strength-to-weight, cost-effective solution.

What fluids are compatible with these connectors?

They work with deionized water, purified water, ethylene glycol/water mixtures, propylene glycol/water mixtures, and fluorinated fluids.

What is the operating temperature range?

The standard operating range is -40°C to 120°C, making it suitable for most demanding liquid cooling applications.

Are these connectors leak-proof during operation?

Yes. The advanced EPDM/FVMO sealing system ensures zero-leakage performance under rated working pressures to safeguard your electronic systems.

Can you customize sizes, threads, or sealing materials?

Yes. We support full OEM/ODM customization for non-standard thread sizes, specific housing materials, or specialized sealing requirements.
