Liquid cooling (water cooling) connector for rack mount BLQ4

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).
