Cool vest fittings (joints, connectors, couplings)

For the prevention and measures against heat stroke.

This is a connector for cool vests that is effective for preventing heatstroke (Breakaway Series). It is utilized in sports, work, and disaster sites. It can be used with gases and liquids. The Breakaway Series connector can be disconnected simply by pulling, without the need to press a thumb push button. Thanks to the double automatic shut-off valve, the liquid is automatically cut off even during fluid delivery, making it safer and more effective for enhancing productivity.

AseptiQuik S for Sterile Connection

For regenerative medicine and diagnostic drugs! We have developed a small sterile connection fitting. (It can also be applied for sterile attachment and detachment.)

We have developed a product with a smaller diameter tube compared to conventional aseptic connection fittings. This product allows for the aseptic transfer of liquids, even in small quantities. It can be used for various applications such as cell therapy, antibody production, small-scale protein formulations, and clinical trials. Since this product does not require aseptic connection equipment, it enables aseptic drug transfer in locations without power (outdoors, disaster areas). In hospitals, nurses do not need to learn how to operate the equipment, allowing for aseptic connections without initial investment. Additionally, CPC also sells aseptic disconnect joints. When combined with aseptic disconnect joints, it enables aseptic connection and disconnection, allowing for repeated aseptic transfers. For more detailed information on aseptic attachment and detachment, please contact the CPC Japan office. You can watch a video about Aseptic Quick S at the following site: http://www.youtube.com/watch?v=0MTO-Z58leM&feature=youtu.be

PCV Pipe CUPLA - Weld-Free Connection to Copper Pipes

Easy Connection with a Single Lever Operation - Ideal for Pressure Testing, Vacuuming, and Refrigerant Charging

"PCV Pipe CUPLA" is a quick connect fluid coupling designed for copper pipe connections. No welding, machining, or tightening is required—pipes can be easily and directly connected. Its dual-seal structure on both the pipe end face and outer surface ensures excellent airtightness and vacuum resistance, supporting vacuum levels down to 0.13 Pa (0.001 mmHg) during connection. A wide range of sizes and sealing materials are available to meet the needs of manufacturing processes for air conditioners, refrigerators, and packaged systems. Features: - No welding, machining, or tightening required - Excellent airtightness and vacuum resistance - Size variations to match pipe outer diameters - Wide selection of mounting thread sizes Note: PCV400, PCV500, and PCV1000 are made-to-order products.
