                  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.
