In-hospital infection prevention fittings (joints, connectors, couplings)

No liquid leakage, one-touch connection is possible.

It protects patients and healthcare workers from infectious materials such as blood, excrement, and body fluids, and is effective in preventing hospital-acquired infections. This joint (connector) minimizes leakage to nearly zero during attachment and detachment thanks to its non-spill valve. The non-spill design allows for connections under pressure, and its material, polypropylene with glass fibers, is compatible with many chemical agents. It can be attached and detached with one hand using a one-touch button, and the colors allow for visual differentiation of piping. <Features of CPC Plastic Fittings> 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 disconnection accidents during use. In the valve type, even when removed under pressure, the liquid (gas) automatically stops. 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.

Liquid cooling (water cooling) connector for rack mount BLQ4

Joint (coupling joint) with a patented anti-fixation structure.

It achieves a highly reliable, leak-free connection and disconnection to protect valuable electronic products. The BLQ4 is specially designed for rack-mounted liquid cooling and utilizes patented valve technology that eliminates leaks and withstands long-term connections. The BLQ4 is specifically designed for applications where connection and disconnection, as well as the latching mechanism, are maintained by system functions other than the connector. Instead of a latch, the BLQ4 features chamfered edges and a tip that fits the connector during connection. The BLQ4 uses the same innovative valve technology as the LQ4. Like all products in the LQ series, the BLQ4 employs sealing materials that can seal at multiple points to ensure the reliability of the connector (rather than a single seal like an O-ring).
