UQD couplings

  • Quick disconnect according to the OCP UQD standard
  • Four sizes: UQD02, UQD04, UQD06 and UQD08
  • Leak-free quick disconnect for electronics liquid cooling

 

CEJN UQD (Universal Quick Disconnect) is a quick disconnect series designed for liquid cooling of electronics. UQD is a global quick disconnect standard developed by the Open Compute Project (OCP), enabling interoperability between products from different manufacturers that comply with the UQD standard.

The CEJN UQD range includes four sizes: UQD02, UQD04, UQD06 and UQD08. The series has nominal flow diameters ranging from 3.2 to 12.7 mm and a max working pressure of 10 bar. The couplings are made of stainless steel (AISI 303) and use EPDM seals. Red and blue color coding helps identify connections in the cooling circuit.

 

Applications: Liquid cooling systems in data centers and other electronics applications.
