Fittings (joints, connectors, couplings) that are resistant to bubble contamination.

No liquid leakage, one-touch connection is possible.

A joint that minimizes leakage to nearly zero during attachment and detachment thanks to a non-spill valve. The non-spill design allows for connections under pressure, and it is made from glass fiber-reinforced polypropylene, making it 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. <CPC Plastic Joint Features> Lightweight and low cost. Rust prevention. Usable for both gases and liquids. All-plastic construction is also disposable. Products compatible with dust-free clean rooms are suitable 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, liquids (gases) are automatically stopped. There is a wide range of couplings made from plastics that have been confirmed for safety, such as NSF standard C-2 and USP type VI, ensuring food safety.

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.
