                LQ4

                LQ4 Series quick disconnect couplings provide ultra-reliable, dripless connections and disconnections that protect valuable electronics. Designed specifically for liquid cooling applications, LQ4 uses patent-pending valve technology that eliminates drips and is able to withstand long-term use.

                 
                Features Benefits
                Non-spill design Disconnect under pressure with no spills
                Redundant sealing when connected Extra protection from leaks
                Color-coding Instant visual difference in cooling lines
                No seal friction in connected state Ultra-reliable protection from drips at disconnect even after long periods in connected state
                Enhanced latch design Easy to see orientation on manifolds and tubing
                Lower, ergonomic profile Meets size requirements for space-constrained electronics
