UQDP-04TMB03-R000 Specs: Performance & Datasheet Info
The UQDP-04TMB03-R000 is an industrial-grade, non-spill fluid quick disconnect coupling engineered specifically for high-density electronic liquid cooling circuits, supercomputing nodes, and critical fluid power assemblies. Designed with a dry-break mechanism, it prevents fluid loss during maintenance and ensures signal-path isolation on high-power chassis assemblies.

Component Schematic & Signal Isolation
Part-Number Breakdown
The system nomenclature follows strict industrial identification parameters:
- UQDP: Ultra-Quick Disconnect Premium series.
- 04: Nominal Flow Diameter (DN04 / 4mm nominal bore size).
- TMB03: Thread Male BSPP (G) 3/8" connection format.
- R000: Standard design revision equipped with high-durability FKM seals.
Integration & Maintenance FAQs
What is the exact torque specification for installing the UQDP-04TMB03-R000 thread?
The exact installation torque specification is 15 Nm (11.06 lb-ft) into a clean, dry G 3/8" female port. Over-tightening may damage the thread interface or deform the primary seat sealing surfaces.
How does the FKM seal react to long-term exposure to water-glycol coolants?
The integrated Fluorocarbon (FKM) seals exhibit excellent chemical resistance and thermal stability when exposed to typical water-glycol mixtures up to 120°C, preventing degradation and micro-leaking.
What is the burst pressure margin safety factor for this coupling?
The coupling features a 4:1 safety factor. While the continuous operating limit is rated at 16 bar (232 PSI), the absolute maximum burst pressure is engineered at 64 bar (928 PSI).
Does the R000 designation support hot-swapping under full operating pressure?
No. Although the non-spill flat-face design minimizes fluid loss, we recommend de-pressurizing the system to below 3 bar before decoupling to prevent rapid seal displacement or transient fluid spray.
