Plastic Quick Disconnect Couplings and Fittings

Colder’s plastic quick disconnect couplings can be found in a wide range of general purpose, medical, bioprocessing and chemical management applications. Couplings, fittings and connectors are available in ABS, acetal, polycarbonate, polypropylene, polysulfone, PTFE and PVDF. Additional materials are available for custom projects.

General purpose

Colder has developed a large base of general purpose couplings that are uniquely designed to make general air and fluid handling applications cleaner, faster and safer. Extensive use of non-spill technology increases equipment modularity and minimises spills and service times. Optional IdentiQuik RFID capabilities can help manufacturers reduce product liability and increase device safety.

Medical grade

The medical-grade materials used in Colder’s couplings meet the most stringent requirements of USP Class VI, MEM elution, agarose overlay, hemolysis in vitro and USP physicochemical tests. These quick disconnect couplings are suitable for use in a wide variety of medical and biopharmaceutical applications.

Medical companies around the world rely on Colder’s quick disconnect couplings to secure tubing connections and disconnections for a wide variety of medical devices and equipment. Colder’s couplings eliminate accidental misconnections and create cleaner, faster, safer and smarter device connections.


Biopharmaceutical manufacturers incorporate single-use systems into their processes to increase productivity, add flexibility, minimise risk and reduce cost throughout their facilities. Whether upstream in fermentation or downstream in formulation or fill processes, Colder’s USP Class VI couplings and connectors make reliable, flexible and sterile connections throughout the bioprocess.


For safe extraction of fluids from jerry cans, drums and intermediate bulk containers (IBCs), Colder offers several dip-tube based systems of different sizes and materials. Virtually any container can be used with a DrumQuik system to dispense the chemical or food-based fluid in a "closed" manner. This minimises the potential for dangerous chemical exposure while protecting the purity of the chemicals themselves from contamination.

Food grade

Quick disconnect couplings are preferred over general fittings for fluid control because they incorporate built-in shut-off valves that prevent spillage, allow multiple disconnections and faster servicing. This also enables tubing to be disconnected without having to turn off the water supply. Many Colder couplings are NSF listed to create cleaner, faster and safer connections with both plastic and copper tubing.

High purity

Colder offers many quick disconnect couplings and connectors made from high-purity materials for use with agressive chemicals found in bioprocessing, semiconductor and similar industries. These rugged connectors offer broad chemical compatibility and protect both workers and the environment from contact with dangerous fluids. Optional RFID, metal-free construction, Viton seals and other high-purity features help make chemical handling cleaner, faster, safer and smarter.
