Product Description

Hongxiang MBT series liquid-cooled couplings are high-performance, lightweight fluid connectors designed for liquid cooling systems. Based on the ten product images, the connectors feature a sleek, compact aluminum alloy body with smooth surface treatment, precise thread design, and integrated sealing structure—combining durability, superior sealing, and wide fluid compatibility. These quick couplings are ideal for high-flow applications in data centers, AI servers, medical equipment, and new energy systems, perfectly matching the practical scenarios shown in the product images.

As displayed in the images, the connectors adopt an EPDM sealing system (HNBR/FKM options available), which delivers reliable, zero-leak performance across -40°C to 120°C. Rated for 20bar working pressure (80bar burst pressure), the plug-and-play design enables fast, tool-free connection and disconnection, simplifying installation and maintenance, and fully reflecting the product’s user-friendly design.

Applications

  • Data Center Servers: Liquid cooling for high-density server racks
  • AI Servers & HPC: Thermal management for high-performance computing
  • Medical Equipment: Precision liquid cooling for MRI, lasers, and diagnostic devices
  • Power Electronics & EV Systems: Cooling for EV chargers, inverters, and power supplies
  • Industrial Lasers & Automation: Reliable fluid connections for industrial equipment
  • PV Inverters & Renewable Energy: Solar and wind energy equipment cooling
  • Test Benches & Research Equipment: Lab-grade liquid cooling solutions

Installation Process

  • Preparation: Refer to the product images to check the plug and socket structure; ensure the connector and mating part are clean and free of debris. Depressurize the system before installation to prevent fluid leakage during operation.
  • Connection: Align the plug and socket according to the alignment mark, then push them together until you hear/feel a positive click, confirming full engagement.
  • Verification: After connection, perform a pressure test to confirm zero leakage before full system operation; check the sealing part to ensure no fluid seepage.
  • Disconnection: Depressurize the system first, then simply pull the plug out of the socket for maintenance or replacement.

FAQ

What are the advantages of the MBT series?

The MBT series features lightweight aluminum construction , multiple connection options, and a wide range of sizes (DN05-DN12), making it highly versatile for different liquid cooling applications. Additionally, the plug-and-play design and zero-leak sealing enhance usability and reliability.

What materials are used in these connectors?

The body is made of high-strength aluminum alloy for light weight and corrosion resistance, with EPDM seals (HNBR and FKM options available for low-temperature or special fluid compatibility). The surface treatment of the aluminum alloy effectively prevents corrosion, extending the product’s service life.

What fluids are compatible with these connectors?

They work with deionized water, purified water, ethylene glycol/water mixtures, propylene glycol/water mixtures, oils.

What is the operating pressure and temperature range?

The working pressure is 20bar (80bar burst pressure), with a temperature range of -40°C to 120°C, which is sufficient to meet the working conditions of most liquid cooling systems, including the harsh environments shown in the product’s application scenarios.

Are these connectors suitable for high-flow applications?

Yes. The MBT series is designed for high flow rates, with sizes up to DN12 supporting flow rates up to 120 L/min. The smooth internal structure reduces flow resistance, making them ideal for large-scale cooling systems such as data centers and AI servers.
