LQ2

The LQ2 Series with 1/8” flow is designed specifically for liquid cooling applications. With a small form factor for tight spaces, LQ2 connectors offer a high-flow capacity to optimize system performance while providing ultra-reliable, dripless connections and disconnections to protect valuable electronics. LQ2 fittings use patent pending valve technology that eliminates drips and are designed for long-term use. EPDM and FKM seals are standard options for compatibility with glycol/water or dielectric coolants. For other material and termination options see your regional CPC sales representative.
