CPC

CPC (Colder Products Company) makes quick disconnect couplings for liquids and gases in plastic and metal. The range covers standard couplings with and without shut-off valves, non-spill designs, food and beverage couplings, chemical-resistant versions, medical connectors, multi-line connectors, hybrid and RFID couplings, and connectors for drums and bottles.

Liquid cooling in the data centre is a key focus: the Everis LQ2 to LQ8 series and the BLQ blind mate couplings open and close coolant loops at cold plates, rack manifolds and CDUs without drips, even under pressure and after long periods in the connected state. Depending on the series, operating ranges extend from -40 to 138 °C and up to 17.3 bar.

How to choose CPC

What matters when choosing: properties, comparison and typical applications.

Selecting a CPC coupling

The key factors are the fluid, pressure and temperature, whether any fluid may escape on disconnection, and the line termination. The table maps typical requirements to the categories.

Requirement	What to look for	Where to find it
Coolant loop on electronics	drip-free, long-term connected, EPDM or FKM depending on coolant	Liquid cooling (Everis)
Disconnect under pressure without leaks	non-spill valves on both halves	Non-spill couplings, Liquid cooling (Everis)
Water, air, process fluids	POM, polypropylene or brass body, with or without shut-off	Standard couplings
Beverage and food	NSF series, seals to FDA	Food and beverage couplings (NSF)
Acids, alkalis, high-purity fluids	PVDF body, FFKM or Chemraz seal	Chemical-resistant couplings
Several lines or signals	multi-line connectors, hybrid and RFID couplings	Multi-line connectors, Hybrid and RFID couplings

Applications

Data centre - Cold plates, rack manifolds and CDUs can be serviced without draining the coolant loop.

Machinery and plant - Connect and disconnect cooling water, compressed air and process fluids quickly.

Medical and laboratory - Tubing on devices is connected and released with one hand.

Food and chemicals - Matched materials for beverages, cleaning agents and aggressive fluids.

Frequently asked questions about CPC couplings

What does drip-free mean for Everis couplings?: The valves close before the sealing faces separate. No coolant escapes on disconnection, even when the loop is pressurised and the coupling has been connected for a long time.
Which seal suits glycol/water and which suits dielectric coolants?: EPDM is the standard seal for glycol/water mixtures. FKM is used for dielectric coolants and oils. The Everis LQ2, LQ4 and LQ6 series are available with both seals.
What pressures and temperatures are possible?: That depends on the series. Across the range, ratings go up to 17.3 bar and from -40 to 138 °C. The Everis LQ4, LQ6, LQ8, BLQ4 and BLQ6 series are rated from vacuum to 8.3 bar, BLQ2 to 13.8 bar.
What is a blind mate coupling?: A coupling that connects automatically when a module slides into the rack, with no hand access needed. The Everis BLQ series tolerate axial misalignment and allow full flow even when not fully engaged.
How do I tell supply from return?: Many Everis couplings come colour-coded, for example in blue and red. Use the colour filter to find the matching versions.
