Liquid-cooling connector
This is a set of high-precision, stainless-steel connectors and valve‑core assemblies specially designed for liquid‑cooling systems. Manufactured using CNC turning and precision molding processes, they feature exceptionally smooth surface finishes and tightly controlled sealing‑surface tolerances, making them well suited for high‑pressure fluid‑circulation applications. The components include right‑angle connectors, straight‑insertion connectors, quick‑connect connectors, valve cores, valve stems, and other configurations, enabling connection, sealing, on/off control, and rapid replacement of liquid‑cooling lines. These products are widely used in liquid‑cooling thermal management systems for industrial equipment, new‑energy applications, and medical devices, offering robust performance characterized by high pressure resistance, corrosion resistance, leak‑free operation, and extended service life.

1. Material and Craftsmanship
- Core material : Primarily made of 304/316L medical‑grade or industrial‑grade stainless steel; in certain high‑pressure applications, high‑strength alloy steels are used. These materials exhibit excellent resistance to corrosion by coolants (water/glycol solutions) and to high‑pressure shock loads, making them suitable for long‑term cyclic operating conditions.
- Processing technology : Employing high-precision CNC turning, the fittings’ threads, tapered surfaces, circlip grooves, and sealing grooves are all formed in a single operation, with dimensional tolerances controlled to the micrometer level. The sealing surfaces undergo mirror‑polishing to ensure gapless contact with the sealing ring. For certain fittings, the quick‑connect design is heat‑treated to enhance hardness, guaranteeing wear resistance and reliability under repeated mating cycles.
2. Analysis of Part Structure and Function
Location Part Appearance Features Typical Applications and Functional Inference Top left Right-angle stainless steel fitting, with internal bores and external threads at both ends, featuring a 90° bent design. Right-angle adapter for liquid‑cooling tubing, designed to change the flow direction; the external threaded section interfaces with equipment or piping, while the internal bore serves as the coolant passage. Its compact design is ideal for tight installation spaces. Middle and upper Straight‑type liquid‑cooling connector: one end features a tube‑insertion section with a hexagonal locating feature, while the other end is equipped with an external thread. Pipe‑in‑pipe straight connector: the insertion section can be directly inserted into the hose and secured with a clamp, while the threaded section connects to the equipment end. The hexagonal design facilitates wrench tightening, making it suitable for both rigid and flexible liquid‑cooling lines. Upper right Large-diameter quick‑connect liquid‑cooling fitting, with a tower‑shaped male tube section on one end and a hexagonal nut on the other. High‑flow liquid‑cooling pipeline quick‑connect fitting, featuring a pagoda‑style design that accommodates large‑diameter hoses; the hexagonal nut section can be threaded directly onto the equipment side, making it ideal for high‑flow, large‑bore liquid‑cooling systems. Bottom left 1 Small T‑shaped valve core assembly, with disc‑shaped ends and a bifurcated support in the middle. Valve spool for liquid‑cooled valves / check valve spool; the T‑shaped design enables unidirectional fluid flow and shut‑off, making it suitable for backflow prevention in compact liquid‑cooling circuits. Bottom left 2 Long-stem valve core assembly, with a disc-shaped sealing head at one end and a support flange at the other. The main spool of the liquid‑cooling control valve features a disc‑shaped end that serves as the sealing surface, while the stem functions as a guiding structure, enabling flow regulation or on/off control in liquid‑cooling systems. Middle and lower Long‑stem valve stem component, with a threaded section at one end and a hexagonal drive head at the other; the stem body is a smooth cylinder. The stem assembly of the liquid‑cooled control valve features a threaded section that mates with the valve spool and valve body, and a hexagonal head for wrench actuation, enabling the valve to open, close, or modulate. Bottom right 2 Multi‑step quick‑connect fitting: one end features a spigot section with a tower‑shaped design and a hexagonal locking mechanism, while the other end is equipped with an external thread. Universal liquid‑cooling quick‑connect fitting; multi‑step, tower‑shaped segments accommodate hoses of various diameters; hexagonal design ensures secure locking and fixation; designed for connecting liquid‑cooling circuits in industrial equipment. Bottom right 1 Quick‑connect coupling with an internal bore and ball‑bearing mechanism, featuring a retaining groove on the outer circumference and a threaded end. Liquid-cooling pipeline quick‑connect fitting (female end), featuring a ball‑lock mechanism for self‑locking and sealing in a quick‑plug configuration, with a threaded section for connection to equipment. It enables rapid plug‑in/plug‑out and secure sealing, making it ideal for liquid‑cooling systems that require frequent disassembly and reassembly. 3. Overall Characteristics and Application Scenarios
- Sealing performance The sealing surfaces, conical surfaces, and threads of the connector are all precision‑machined; when used with an O‑ring seal, they achieve zero leakage and can withstand the operating pressures of liquid‑cooling systems—typically up to 1–10 MPa—thereby preventing equipment failures caused by coolant leaks.
- Adaptability It encompasses a variety of connection types, including right-angle, straight‑in, quick‑connect, and threaded fittings, and is compatible with diverse interface formats such as hose, rigid pipe, and equipment ports. This allows for flexible configuration and assembly of liquid‑cooling loop systems, meeting the installation space and flow‑rate requirements of different devices.
- Durability : The stainless steel material offers excellent corrosion resistance, making it suitable for long-term circulation with coolant containing corrosion inhibitors; the wear‑resistant design of the quick‑connect fitting can withstand hundreds of mating cycles, meeting the demands of equipment maintenance and pipeline disassembly/reassembly.
- Application areas It is widely used in liquid-cooling thermal management systems for industrial robots, servo motors, new-energy battery packs, medical devices, and data-center servers, serving as the core component that enables fluid connection and control within the liquid-cooling loop.
