Liquid cooling fittings (joints) for supercomputers, wind power generation, and medical applications!

No liquid leakage, one-touch connection is possible.

We also offer fittings that minimize leakage to nearly zero during attachment and detachment, thanks to a non-spill valve. They are widely used in cooling applications for PCs and servers, which are sensitive to liquids. They are also utilized in medical lasers, CT scanners, industrial printers, and liquid cooling for aircraft components. Made of plastic, they are lightweight, compact, inexpensive, and resistant to rust, with a wide range of standards available in various sizes and mounting types. The non-spill design allows for connections under pressure, and they are made from glass-fiber reinforced polypropylene, compatible with many chemical substances. The one-touch button allows for one-handed attachment and detachment, and the color coding enables visual differentiation of piping. For high-temperature applications, there is also the HFC35 series of fittings made from polysulfone (as shown in the photo). <Features of CPC Plastic Fittings>. Lightweight and low-cost. Rust prevention. Usable for both gases and liquids. All-plastic versions are also available for disposable use. Dust-free cleanroom compatible products are suitable for medical and precision machinery applications. The tubes can rotate freely, reducing twisting and preventing tube detachment accidents during use. In valve-equipped types, liquids (gases) are automatically stopped even when disconnected under pressure.

High Purity Chemical and Semiconductor Non-Spill Fittings (Joints/Connectors)

No liquid leakage, one-touch connection is possible.

The CPC CQG series uses materials suitable for high-purity chemical applications. It features non-spill fittings that are optimal for preventing metal leaching, resulting in almost zero liquid drippage during attachment and detachment. This helps prevent the splashing of hazardous liquids (ensuring safety and preventing product failure). With high functionality such as metal-free contact parts, it is suitable for use with high-purity and corrosive chemicals, as well as ultra-pure water lines. It is widely adopted in industries that require high purity, such as semiconductor, resist, and pure water applications. It does not use lubricants like silicone oil. International patents have been obtained. Made of polypropylene. There is also a compact Kemquick available. Please search for 'Kemquick' within Ipros. (Available in PP or PVDF). <CPC Plastic Fitting Features> Lightweight and low-cost. Rust prevention. Usable for both gases and liquids. All-plastic construction allows for disposable options. Dust-free cleanroom compatible products are available for medical and precision machinery applications. The tube can rotate freely, reducing twisting and preventing tube detachment accidents during use. In the valve type, even when removed under pressure, the liquid (gas) automatically stops. It is effective for preventing metal ion leaching.
