PRODUCT PARAMETER
Welcome to Our Website,We Are Happy to Serve You
Hongxiang MDC series liquid-cooled couplings are high-performance, all-stainless-steel fluid connectors engineered for demanding liquid cooling applications. Built from 316L stainless steel, these quick couplings deliver exceptional corrosion resistance, long-term durability, and zero-leak reliability in even the harshest industrial environments.
Designed for high-flow efficiency, the MDC series supports a wide range of sizes from DN04 to DN25, making them ideal for large-scale cooling systems. With standard EPDM seals (optional HNBR/FKM available), they maintain stable performance across a broad temperature range of -40°C to 120°C and a working pressure of 20bar (burst pressure 80bar). The tool-free plug-and-play design simplifies installation and maintenance, while multiple connection options (threaded, hose barb, quick-fit) ensure seamless integration into any system.
Applications
• Data Center Servers & HPC: High-flow liquid cooling for high-density server racks and supercomputers
• Medical Equipment: Precision cooling for MRI machines, lasers, and diagnostic devices
• New Energy Systems: EV charging piles, three-electric systems, and battery energy storage
• Industrial Lasers & Automation: Reliable fluid connections for high-power industrial equipment
• Power Electronics & PV Inverters: Cooling for solar inverters, wind turbines, and power supplies
• Test Benches & Research Labs: Lab-grade liquid cooling solutions for precision experiments
• Outdoor Harsh Environments: Dust-proof and salt-proof performance for outdoor equipment
Installation Process
1. Preparation: Ensure the connector and mating surface are clean and free of debris. Depressurize the system before installation to avoid fluid spray.
2. Connection: Align the plug and socket, then push them together until you hear/feel a positive click, confirming full engagement.
3. Verification: Perform a pressure test to confirm zero leakage before full system operation.
4. Disconnection: Depressurize the system, then simply pull the plug out of the socket (no tools required) for maintenance or replacement.
⚠️ Note: Never disconnect the connector while the system is under pressure. Avoid damaging the sealing surface during installation or removal.

FAQ
1. What makes the MDC series different from other quick connectors?
The MDC series is constructed entirely from 316L stainless steel, offering superior corrosion resistance compared to aluminum or brass connectors. It also supports a wider range of sizes (DN04 to DN25) and connection options, making it highly versatile for diverse liquid cooling applications.
2. What sealing materials are available?
Standard sealing material is EPDM. Optional seals include HNBR and FKM, which are suitable for different fluid compatibility and temperature requirements.
3. What fluids can these connectors handle?
They are compatible with deionized water, purified water, ethylene glycol/water mixtures, propylene glycol/water mixtures, oils, and fluorinated fluids, covering most common liquid cooling media.
4. What is the maximum working pressure and temperature?
The working pressure is 20bar (burst pressure 80bar), with a temperature range of -40°C to 120°C, suitable for most industrial and commercial liquid cooling systems.
5. Are these connectors suitable for outdoor use?
Yes. The 316L stainless steel construction and dust-proof/salt-proof design make them ideal for outdoor environments, such as solar inverters and wind energy equipment.
