Universal Quick Disconnect Blind-Mate (UQDB) was initiated and led by Intel to establish an open standard blind mate interface for liquid cooling systems and enable physical interchangeability among products from different manufacturers. Netonx UQDB is available in four sizes: 02, 04, 06 and 08. Both the plug and socket use UNF threaded tail end connections and are interchangeable with other products compliant with the OCP specification.
