LQ4

The LQ4 Series quick disconnects with ¼” flow offer a relative high-flow capacity to optimize system performance while providing ultra-reliable, dripless connections and disconnections to protect valuable electronics. LQ4 fittings are designed for long-term use and feature patent pending valve technology that eliminates drips. 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.
