    Everis PLQ4

    See Everis PLQ4 Products

    The Everis PLQ4 Series of quick disconnects provides ultra-reliable connections and dripless disconnections that protect sensitive electronic systems being cooled via liquid cooling. Built of polyphenylsulfone (PPSU), a high-performance thermoplastic, the Everis PLQ4 connector is lightweight and inherently resistant to galvanic corrosion. Everis PLQ4 connectors are rated UL94 V0 flame retardant and are easy to use making them a perfect choice for liquid cooling of electronics applications. These industry-leading connectors offer a high-flow capacity to optimize thermal management system performance. The Everis PLQ4 Series uses patent-pending CPC-developed valve technology that eliminates drips and is specifically designed for long-term connected states.
