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).

The component "female nut (NF)" has silver plating on the female threads to prevent galling and seizing, ensuring secure tightening. Additionally, two leak test ports are positioned along the gasket line, making it easy to confirm gasket installation and conduct leak tests. 【Components and Features】 ■ Female Nut (NF) - Silver plating on the female threads prevents galling and seizing, ensuring secure tightening. ■ Sleeve (S) - Smooth inner surface finish achieved through our unique electropolishing and other processes. ■ Gasket (G) - Nickel is used as the standard material, achieving high sealing performance with the sleeve through tightening. ■ Male Nut (NM) - High strength is achieved by adopting rolled threads, ensuring secure connections. *KITZ SCT offers various solutions for fluid-related issues in semiconductor manufacturing.
