In high-integrity fluid power and thermal management systems, the selection of connection hardware determines the ultimate safety margin and efficiency of the overall loop. The UQDP-04TMB02-L000 represents a state-of-the-art solution designed for critical environments where dry-break operations, structural durability, and high flow capacities are mandatory. Utilizing a double shut-off architecture, this coupling minimizes fluid loss during disconnection and prevents atmospheric contamination of the process line.
From industrial liquid cooling of high-density server racks to aerospace testing manifolds, fluid integrity must be maintained under fluctuating pressure and temperature regimes. The UQDP-04TMB02-L000 utilizes advanced seal topology and high-precision mechanical tolerances to eliminate stochastic leakage vectors. This technical evaluation details the physical parameters, fluid dynamics, and operational limits of this industrial component, providing design engineers with the integration criteria required for high-reliability systems.
Detailed Datasheet Breakdown of the UQDP-04TMB02-L000
The construction of the UQDP-04TMB02-L000 relies exclusively on premium metallurgy and specialized elastomer compounds. The main structural body is machined from 316L stainless steel (UNS S31603), which has undergone electropolishing to optimize corrosion resistance and reduce surface friction during coupling cycles. Electropolishing removes microscopic surface defects and creates a chromium-rich oxide passivation layer that prevents pitting in harsh chemical environments.
The nominal port size is configured with a 1/4" NPT Male thread conforming to ANSI/ASME B1.20.1 standards. With a maximum body diameter of 22.0 mm and an overall coupled length of 58.5 mm, this component is highly optimized for confined envelopes. The dry weight of the assembly is restricted to 85 grams, reducing mechanical strain on rigid tubing manifolds. Elastomeric sealing is achieved via a high-fluorine content FKM (Viton) compound, which offers exceptional resistance to chemical degradation, ozone exposure, and thermal aging.
Performance Metrics & Operational Limits of UQDP-04TMB02-L000
Operational safety in high-pressure pneumatic or hydraulic systems demands a conservative design margin. The UQDP-04TMB02-L000 boasts a maximum working pressure of 250 bar (3625 psi), making it compatible with severe-duty hydraulic actuators and high-pressure gas distribution networks. To ensure safety, each unit is proof-tested to 375 bar (5438 psi), while the ultimate burst pressure of the assembly exceeds 1000 bar (14500 psi), yielding a robust 4:1 safety factor against catastrophic structural failure.
The flow coefficient (Cv) of the coupled assembly is rated at 0.42, ensuring minimal pressure drop (ΔP) across the valve seat during high-velocity fluid transfers. For instance, in a water-cooling circuit operating at a flow rate of 5 liters per minute, the localized pressure drop remains negligible. Vacuum integrity is equally secure; the coupling has been certified via helium mass spectrometry leak testing to exhibit a leakage rate of less than 1 x 10^-6 mbar·l/s, satisfying the rigorous demands of ultra-pure gas delivery and closed-loop cooling systems.
