Liquid-cooling connector
This is a stainless-steel, internally threaded, pagoda‑style liquid‑cooling tubing connector, manufactured via CNC turning in a single-piece process. One end features a hexagonal internal thread, while the other end is a multi‑step, pagoda‑shaped hose‑insertion section. Specifically designed for liquid‑cooling systems, this component enables a sealed connection between an equipment’s threaded port and a flexible hose, offering high pressure resistance, corrosion resistance, secure hose retention, and low flow resistance. It is widely used in liquid‑cooling thermal management systems for industrial equipment, new energy applications, and data centers.

1. Material and Craftsmanship
- Core material : Constructed from industrial-grade 304/316L stainless steel, it exhibits excellent resistance to corrosion by coolant fluids (water/glycol solutions), withstands the pressure surges and temperature fluctuations inherent in liquid‑cooling systems, and is suitable for long‑term cyclic operating conditions, while also meeting equipment requirements for cleanliness and minimal impurity leaching.
- Processing technology : Manufactured as a single piece using high-precision CNC turning, with excellent coaxiality between the internal threads, hexagonal face, and tower‑shaped section; the internal thread accuracy meets standard tolerance requirements, the step dimensions of the tower section are highly precise, and the surface finish is exceptionally smooth. The surface undergoes passivation treatment to enhance corrosion resistance and surface quality, thereby reducing the risk of fluid residue and bacterial growth.
2. Structural and Functional Analysis
- Overall structure : The part features a two‑section stepped cylindrical structure, divided into two components:
- Internal-threaded hex socket end : The right end features a hexagonal nut design with a standard internal thread; the thread profile is intact and highly precise, enabling connection to equipment‑side or externally threaded pipeline interfaces. The hexagonal face facilitates wrench tightening, ensuring proper torque and sealing while preventing loosening and leakage.
- Pagoda-type hose coupling section : The left end features a multi‑step tower structure, with multiple annular steps arranged along the outer circumference; the step diameters increase progressively to accommodate hose inner diameters of various specifications. After the hose is inserted, it is secured with a clamp or hose clamp; the annular steps enhance friction, preventing the hose from coming loose under high‑pressure fluid impact and improving connection reliability. The internal bore is a straight‑through fluid passage, ensuring smooth coolant flow and minimizing flow resistance.
- Core Features As a hose‑end connector for liquid‑cooling systems, it provides a sealed connection between the equipment‑side internal threaded interface and the hose, ensuring stable coolant circulation. Its multi‑step, stepped‑tower structure combined with a hexagonal locking design effectively prevents hose disconnection and thread loosening under high‑pressure and vibration conditions, thereby enhancing the operational stability of the liquid‑cooling system.
3. Features and Application Scenarios
- Anti‑shedding and sealing performance : The multi‑step pagoda‑style structure, in conjunction with a clamp, ensures secure hose retention and prevents disconnection; the internal threads mate with the equipment interface, and when paired with a sealing ring, achieve an ingress protection rating of IP65 or higher, withstand the typical operating pressures of liquid‑cooling systems, and prevent coolant leakage.
- Compatibility and Installation Convenience : A combined design featuring a standard internal thread and a multi‑step tower structure, compatible with liquid‑cooling hoses and equipment interfaces of various specifications. It offers convenient installation without the need for special tools, making it ideal for mass assembly and on‑site maintenance.
- Durability and Environmental Adaptability Stainless steel’s excellent corrosion resistance and high hardness enable it to withstand fluid erosion, temperature fluctuations, and mechanical vibrations under long-term cyclic operating conditions. It is resistant to rust and deformation, thereby extending the service life of fittings and reducing equipment maintenance costs.
- Application areas It is widely used in liquid-cooling thermal management systems for industrial robots, servo motors, new-energy battery packs, data-center servers, and energy-storage devices, serving as a core foundational component for fluid transport and equipment connectivity.
