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.

Everis® LQ4S Stainless Steel Quick Disconnects (QDs) for Liquid Cooling Systems

CPC has added a line of stainless steel fluid connectors to its Everis® product line. These quick disconnects (QDs) are designed and built for liquid cooling applications where specifying engineers want greater resistance to corrosion in a metal QD.

Features		Benefits
	Dry break, non-spill valves		Disconnect under pressure with no spills
	Redundant multi-lobed seals		Extra protection from leak-causing contaminants and debris
	High flow capacity with low pressure drop		Efficient, cost effective cooling system
	EPDM seals		Compatibility with common coolants and application temperatures
	Ergonomic body and latch design		Simple intuitive one handed operation and audible click signals secure connection
	Color coding		Instant visual identification of cooling lines
	Low profile		Meets size requirements for space-constrained electronics
	Barbed and threaded terminations		System design flexibility, including providing options
