A fitting catalog that converts sanitary fittings (flanges) to one-touch.

Free yourself from the hassle of putting on and taking off sanitary products!

Most CPC products use resins certified by the FDA (U.S. Food and Drug Administration) and USDA (U.S. Department of Agriculture). The polysulfone products are compatible with sodium hypochlorite, steam, and hydrochloric acid. Products compatible with the MPC series can be used with the APC series and EFC series, which have valves that allow for disconnection under pressure. (Only on the female side. There are no products with valves on the sanitary side.) The APC and EFC series include options with threaded connections, wall-mounted installations, and L-shaped configurations, allowing for combinations with sanitary fittings. A catalog detailing the APC and EFC series can be downloaded from the <comprehensive catalog link>. Please note that unlike the MPC series, the APC and EFC series do not support all sterilization methods. For more details, please contact us.

Small connector for liquid cooling (water cooling) for rack mount, BLQ2.

A 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 BLQ2 is specially designed for rack-mounted liquid cooling and utilizes patented valve technology that eliminates leaks and withstands long-term connections. The BLQ2 is specifically designed for applications where connection and disconnection, as well as the latch mechanism, are maintained by system functions other than the connector. Instead of a latch, the BLQ2 features chamfering and a tip that fit the connector during connection. The BLQ2 uses the same innovative valve technology as the LQ2. Like all LQ series products, the BLQ2 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).
