    Installation & Removal Process

    1
    Preparation Ensure the coupling and mating components are clean, free of debris, and undamaged. Depressurize the fluid system before installation.
    2
    Connection Align the plug and socket, then push straightly until a click sound confirms complete locking.
    3
    Verification Perform a pressure test to confirm no leaks before bringing the system online.
    4
    Disconnection Depressurize the system, then simply pull the plug out of the socket. The coupling will automatically seal to prevent fluid loss.
    Safety Notes
    • Never connect or disconnect the coupling while the system is under pressure.
    • Protect the sealing surface from scratches to maintain long-term leak-proof performance.

    FAQ

    1. What makes the UQD series different from other quick couplings? +
    The UQD series combines 316L stainless steel construction with versatile sealing and connection options, making it suitable for a wide range of demanding liquid cooling applications.
    2. Can I choose different sealing materials? +
    Yes. Standard EPDM seals are suitable for water and glycol solutions. HNBR seals offer better oil resistance, while FKM seals are ideal for high-temperature or chemically aggressive fluids.
    3. What fluids are compatible with these couplings? +
    They work with most common liquid cooling media, including deionized water, glycol mixtures, industrial oils, and fluorinated fluids.
    4. What are the pressure and temperature ratings? +
    Rated working pressure is 20 bar (burst pressure 80 bar), with an operating temperature range of -40°C to 120°C.
    5. Are these couplings suitable for outdoor use? +
    Yes. The 316L stainless steel construction provides excellent resistance to corrosion, salt spray, and extreme temperatures, making them ideal for outdoor and industrial applications.
    6. Do I need tools to install or remove them? +
    No. The plug-and-play design allows for tool-free connection and disconnection, simplifying installation and maintenance.
