High-Quality QD Plug & Socket Bodies for Liquid Cooling Systems
QD Plug & Socket Bodies are precision quick disconnect components for liquid cooling in data centers, AI servers, and industrial fluid systems. Manufactured to OCP UQD standard, our bodies ensure full interchangeability with other approved suppliers. Available in sizes 02–08 with UNF, BSPP, and push-lok connections, stainless steel construction offers corrosion resistance and durability. Advanced valve design enables dripless connection/disconnection, preventing coolant spillage and protecting sensitive electronics. Rated at 20 bar (290 psi) and -40°C to +120°C, these connectors deliver reliable leak-free performance across 5,000+ mating cycles with full RoHS/REACH compliance.

Applications
Our QD Plug & Socket Bodies serve diverse industrial applications:
Cold Plate Liquid Cooling
Manifold assemblies deliver reliable multi-channel coolant distribution for AI server cold plate liquid cooling systems.
Rack-Level Manifold Distribution Loops
Core manifold components construct uniform fluid distribution loops at rack level for cluster thermal management.
Single & Two-Phase Immersion Cooling
Leak-proof manifold structures adapt to both single-phase and two-phase immersion cooling working conditions.
Direct-to-Chip Cooling
Accurate flow allocation supports efficient heat dissipation of high-power GPU and CPU direct-to-chip cooling solutions.
