OCP UQD Quick Disconnect Plug (Male) for Data Center Liquid Cooling

Product Specification

Feature

JINGYE Fittings manufactures OCP UQD quick disconnect plugs for data center liquid cooling in Ningbo, China. Founded in 2008, we support AI server OEMs, liquid cooling integrators, CDU manufacturers, and global procurement teams. Key Product Advantages: 1. Four UQD Sizes and 16 Plug SKUs UQD02, UQD04, UQD06, and UQD08 are available in SAE ORB and BSPP threaded configurations, with red/blue identification options. Representative JINGYE series: JY-UQD-02A, JY-UQD-04A, JY-UQD-06A, and JY-UQD-08A. The complete range includes 16 plug part numbers covering size, termination, and identification choices. 2. OCP UQD Interface Design Designed around the Open Compute Project Universal Quick Disconnect concept for hand-mate liquid cooling connections. The plug is the male half and mates with a corresponding same-size UQD socket. UQD and UQDB are different interface families. Cross-brand mating requires dimensional, sealing, and functional verification with the selected socket. 3. Flat-Face Dry-Break Operation Valved flat-face construction supports rapid service disconnection while limiting coolant loss and air entry. Shutoff performance depends on the complete plug/socket pair, fluid, pressure, and operating conditions. This design suits serviceable liquid cooling loops near sensitive server electronics. 4. SAE ORB and BSPP Terminations SAE ORB options: UQD02 7/16-20 UNF; UQD04 9/16-18 UNF; UQD06 3/4-16 UNF; UQD08 7/8-14 UNF. BSPP options: UQD02 G1/8; UQD04 G1/4; UQD06 G3/8; UQD08 G1/2. Select the termination to match the system port, seal, and assembly requirements. 5. Flow and Pressure-Drop Engineering OCP UQD Rev. 1.0 reference minimum coupled-pair Cv values: UQD02 0.25; UQD04 0.80; UQD06 1.60; UQD08 2.50. The actual Cv and pressure-drop curve depend on the tested plug/socket combination. Flow evaluation can support CDU, manifold, and cold-plate circuit design. 6. Controlled Coolant Loss OCP Rev. 1.0 reference maximum fluid loss per connect/disconnect cycle at 0 psi: UQD02 0.020 mL; UQD04 0.025 mL; UQD06 0.035 mL; UQD08 0.070 mL. These are OCP specification limits, not claimed JINGYE measured results. Project-specific leakage and spillage validation can be specified. 7. Pressure and Thermal Requirements JINGYE catalog working pressure: up to 100 psi (6.9 bar), configuration dependent. OCP Rev. 1.0 specifies a minimum burst pressure of 300 psi (20.7 bar) and reference coolant operation at +17°C ~ +65°C. Actual performance must be established for the selected plug, socket, coolant, and seal configuration. 8. Stainless Steel and Coolant Compatibility Standard plug body: SUS304 stainless steel; SS316/316L options for suitable corrosion-sensitive applications. EPDM and selected FKM seals can be evaluated for deionized water, propylene glycol/water, ethylene glycol/water, and compatible single-phase coolant mixtures. Compound selection depends on fluid chemistry and temperature. 9. Manufacturing and Quality Control JINGYE Fittings operates an ISO 9001:2015 quality management system and precision CNC manufacturing capabilities. Key controls include mating geometry, threads, valve movement, sealing surfaces, cleanliness, visual inspection, and relevant material checks. Leak, pressure, fluid-loss, and cycling tests can be arranged to agreed criteria. 10. OEM Configurations and Second-Source Evaluation Options include ORB/BSPP connections, red/blue identification, material and seal selections, customized packaging, and drawing-based projects. Customers can provide an existing UQD socket or reference drawing for dimensional review and physical cross-mating qualification. OCP-related geometry alone does not establish verified interchangeability. 11. Data Center Liquid Cooling Applications Typical applications include AI/GPU servers, HPC, direct-to-chip cold plates, rack manifolds, coolant distribution units (CDUs), and serviceable server-side cooling loops. JINGYE Fittings supports sample evaluation, mixed-SKU purchasing, OEM projects, and repeat supply for data center liquid cooling equipment manufacturers.
