Component overview
This blind-mate connection is intended for a guided socket-and-plug engagement within a serviceable liquid-cooling assembly. The page describes the documented UQDB04 reference, not interchangeability with every connector carrying a similar interface name.
Construction and interfaces
The photograph shows the UQDB04-size mating components as a discrete pair. The manufacturer lists different external threads for the plug and socket ends, so the two sides must be selected and mounted independently rather than treated as identical fittings.
Selection and documented data
Start with the guide geometry and exact socket/plug drawing, then verify end threads, expected insertion force, coolant, required flow and acceptable pressure drop. The published Cv is a coefficient, not a guaranteed flow rate at an unspecified pressure drop.
Standard and optional configuration
Specify each mating half and its mounting interface, plus seal, material and line termination for the particular order code. Other UQDB nominal sizes exist in the source range, but their dimensions and pictures are not silently transferred to this UQDB04 page.
Application and evidence limits
The source page reports different pressure numbers in a summary and a table. Pressure is therefore deliberately omitted from this product's verified parameter table until its definition, configuration and test conditions are resolved.
Define for quotation
Provide the controlled mating-interface drawing, guide and panel geometry, both end connections, coolant, flow and pressure-drop duty, insertion-force limit, disconnect leakage requirement and acceptance documentation.
