The LQ series, which was developed specifically for liquid cooling of electronics, has a nominal size of 19mm with the new LQ8.
These easy-to-connect, robust, non-spill connectors are known for their reliability in high performance computing, data center applications and other critical thermal management applications. All LQ Series QDs—LQ2, LQ4, LQ6 and LQ8—also offer unique swivel configurations and an integrated thumb latch for easy, one-handed operation in confined spaces like the server racks of large data centers.
LQ Series QDs feature a multilobed seal for redundant protection against leakage and lasting shape retention. Multilobe seals provide greater sealing efficiency than standard O-rings, while requiring less force to connect. The non-spill design allows disconnection under pressure without leaks—critically important in protecting electronics from exposure to fluid and enabling hot swapping of equipment.
