OCP UQDB Blind-Mate Quick Disconnect Socket (Female) for Data Center Liquid Cooling

Product Specification

Feature

JINGYE Fittings manufactures OCP UQDB blind-mate quick disconnect sockets for AI server liquid cooling in Ningbo, China. We serve server OEMs, rack cooling integrators and manifold manufacturers. Key Product Advantages: 1. Four UQDB Sizes and Four Actual SKUs UQDB02: JY-UQDB-02B-01N, 9/16-18 UNF-2A, HEX 17 mm. UQDB04: JY-UQDB-04B-01N, 3/4-16 UNF-2A, HEX 19 mm. UQDB06: JY-UQDB-06B-01N, 7/8-14 UNF-2A, HEX 24 mm. UQDB08: JY-UQDB-08B-01N, 1-1/16-12 UNF-2A, HEX 27 mm. Female sockets with male-thread ends, distinct from UQDB plugs. 2. OCP UQDB Blind-Mate Female Interface The UQDB female socket connects to a corresponding same-size UQDB male plug during server tray insertion. This enables service connections without manual coupling access. UQDB blind-mate and UQD hand-mate are distinct connector families; mating compatibility is checked for the selected pair. 3. Server-to-Manifold Docking Integration Designed for modular AI server trays, rack manifolds and liquid cooling distribution blocks. Integration review considers connector orientation, available mounting envelope, insertion depth, guide rails or alignment pins, and withdrawal clearance. Evaluate socket and plug as one docking system. 4. Alignment, Floating Mounts and Mating Force Blind-mate design involves radial and angular offsets, axial engagement travel, fixed or floating mounting provisions and insertion/withdrawal forces. Alignment limits depend on mating geometry and rack hardware. A 1 mm radial offset is an industry comparison reference, not a universal JINGYE rating. Verify offsets and forces in assembly trials. 5. UNF Threaded Port Connections Four UNF male-thread terminations support equipment-side installation: 9/16-18, 3/4-16, 7/8-14 and 1-1/16-12. Verify the mating port standard, sealing arrangement, thread engagement and tightening procedure. Port sealing is separate from UQDB face sealing. Socket threads differ from the same-size UQDB plug series. 6. Flat-Face Low-Spill Valve Construction Valved flat-face construction helps limit coolant release and air entry during disconnect and reconnection. Relevant qualification tests include connected leakage, disconnected shutoff leakage, fluid loss per cycle and air inclusion. Results depend on the matched pair, coolant and pressure; UQD values do not apply to UQDB. 7. Flow, Pressure and Temperature Engineering JINGYE catalog working pressure is up to 100 psi (6.9 bar), depending on configuration. Coupled-pair Cv, pressure-drop curves, target coolant flow and burst performance should be validated with the intended mating plug. Catalog temperature: -55°C ~ +125°C, dependent on seal and fluid. The complete circuit rating is limited by its lowest-rated component. 8. Stainless Steel and Cooling Fluid Compatibility The standard socket body uses SUS304 stainless steel, with SS316/316L options for suitable projects. EPDM or FKM seals can be selected for compatible DI water, propylene glycol/water and ethylene glycol/water coolant mixtures. Material evaluation includes glycol concentration, corrosion, additives, elastomer swelling and cleanliness of wetted surfaces and valve components. 9. Mating Durability and Quality Inspection JINGYE's UQDB series catalog lists 5,000 mating cycles; qualification depends on the selected plug/socket pair and test conditions. ISO 9001:2015 quality management supports checks of UNF threads, mating dimensions, valve movement, flat sealing faces, surface finish and cleanliness. OEM testing may include repeated docking, insertion force monitoring, vibration, thermal cycles, pressure integrity and post-cycle leakage. 10. OEM Customization and Second-Source Qualification JINGYE Fittings supports precision CNC manufacturing, customer drawings, threaded-end options, stainless steel grades, seal compounds and customized packaging. OEM projects can review mounting tolerance stack-ups, fixed/floating installation, mating plugs and inspection records. Customer-supplied samples or drawings support dimensional comparison, physical cross-mating tests and verified alternative-source procurement. 11. AI Server and Data Center Applications UQDB sockets serve AI/GPU server trays, HPC clusters, direct-to-chip cold plates, rack manifolds, coolant distribution modules and modular liquid cooling loops. JINGYE supports samples, mixed-SKU orders, OEM qualification and repeat production.
