CPC (Colder Products Company) is a manufacturer of push-button couplings. CPC couplings can be used for both gases and liquids. They are ultra-compact, lightweight, and inexpensive, with materials available in engineering plastics, super engineering plastics, and metals. When integrated into machinery, they can be attached and detached without pressure reduction using an automatic valve. Non-spill fittings eliminate liquid drips during attachment and detachment, and they are widely used in liquid cooling for power supplies and inkjet printers. Hybrid connectors enable the connection of liquids and electrical terminals. The multi-type can connect up to 10 lines. Examples of CPC coupling applications include liquid cooling, inkjet printers, motorcycles, automobiles, analytical instruments, semiconductors, high-purity lines, light-resistant lines, micro-tube connections, and drums. Additionally, there are fittings with built-in IC tags, various sterile connection connectors for single-use biopharmaceuticals and regenerative medicine applications, and luer locks (custom orders are also available). Compliance with ISO 9001, RoHS, and REACH is guaranteed, along with extensive safety data for medical and food applications and a proven track record of approvals worldwide. Manufacturing of dust-free products in clean rooms is also possible.
