                  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
