Metal Couplings

Durable and attractive metal quick disconnect couplings can withstand higher pressure and temperature than plastic couplings. Available in chrome-plated brass and die-cast zinc, these couplings are often selected for applications where extended repeated connection cycles are required.

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.


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.

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.
