Danfoss Hansen UQDB04 coupling Universal Quick Disconnect Blind-Mate (UQDB)
One partner, every solution

Danfoss Hansen Universal Quick Disconnect Blind-Mate (UQDB) has been designed with OCP (Open Compute Project) community to set industry standard for thermal management application in data centers. This quick disconnect coupling is available in 4 different sizes (as the UQDB: UQDB02 / UQDB04 / UQDB06 / UQDB08 ) and complies with OCP specification requirements. Danfoss UQDB offers a self-alignment feature to help connect in location with limited access or visibility and guarantees 100% helium-leak testing on every coupling.
