MQD is a quick coupling specification developed by NVIDIA for next generation AI data center liquid cooling systems, primarily supporting the Vera Rubin architecture platform. MQD is the core component supporting the millions of GPU computing deployments. Netonx MQD complies with NVIDIA specifications and is designed for efficient fluid connections within rack level liquid cooling distribution systems. Featuring a flat face sealing structure and optimized internal flow path, it provides low fluid loss during mating cycles while supporting higher flow rates and lower pressure drop for high density data center applications.
