LQ4 Series Chrome-Plated Brass Connectors for Liquid Cooling

LQ4 Series Chrome-Plated Brass Connectors for Liquid Cooling

The LQ4 Series quick disconnect couplings provide ultra-reliable, dripless connections and disconnections that protect valuable electronics. They are designed specifically for liquid cooling applications, and the LQ4 fittings utilize valve technology that eliminates drips and can withstand long-term use. The non-spill design even allows disconnection under pressure. Redundant sealing adds extra protection from leaks. Red and blue color coding provides visual differences in cooling lines. There is no seal friction in the connected state, which allows ultra-reliable protection from drips when disconnecting, even after long periods of being connected. The ruggedness of these couplings makes them able to withstand long-term use. These couplings allow the tubing to move, which eliminates tube kinking.
