Precision metal construction
316L stainless steel and chrome-plated brass are available construction directions, selected by coolant chemistry and project requirements.
Liquid Cooling Technologies
UQD Series Universal Quick Disconnects
Serviceable dry-break connections for server, rack manifold, and CDU liquid cooling loops.
Request technical data
Designed around a defined liquid cooling interface
Final performance and interchangeability are confirmed by nominal size, mating interface, coolant chemistry, pressure loss, and issued model data.
Coolant-specific sealing
EPDM and FKM sealing options are matched to the approved water, glycol, or project-specific coolant formulation.
Controlled separation
Flush-face dry-break architecture is intended to limit coolant release during servicing and hot-swap procedures.
UQD Series
Four published OCP interface sizes
The model code identifies the OCP nominal interface. Hose and port terminations are specified separately.
Compact chassis and internal equipment-loop connections.

- 1/4 in tubing
- Minimum Cv
- 0.25
Server, cold-plate, and higher-flow equipment connections.
- OCP example barb
- 3/8 in tubing
- Minimum Cv
- 0.80
Rack manifold branches and equipment distribution loops.
- OCP example barb
- 1/2 in tubing
- Minimum Cv
- 1.60
Higher-flow rack and cooling distribution integration.
- OCP example barb

Flush-face dry-break connection
The plug and socket close on both sides when separated. This architecture supports service access while controlling the amount of coolant released during a connect or disconnect cycle.
- Hand-mate, latched connection
- Supply and return identification options
- Coolant and seal compatibility review
- Flow coefficient and pressure-drop selection
Technical selection framework

- Issued data
- Cv, fluid loss, leakage, pressure, temperature, and lifecycle report
The OCP specification recommends the catalog statement “Dimensional & performance requirements conform to OCP Universal Quick Disconnect (UQD) Specification rev 1.0” only for products that meet those requirements. Vantimond model compliance should be published after the corresponding dimensional and performance records are available.
From connector interface to rack distribution
Selection starts with the cooling architecture, then confirms connector size, termination, flow demand, coolant, allowable pressure loss, service access, and redundancy.
