Everis LQ4S

See Everis LQ4S Products

The Everis® LQ4S Series of quick disconnects (QDs) provides ultra-reliable connections and dripless disconnections. Manufactured out of stainless steel, a material known for its high performance, the Everis LQ4S dry break QD is inherently resistant to corrosion. As an extension of the popular Everis LQ line, these industry-leading quick release couplings offer a high-flow capacity to optimize thermal management system performance. The Everis LQ4S Series uses patented CPC-developed valve technology that eliminates drips and is purpose designed and built for long-term connected states, such as found in many cooling of electronics applications.
