2C9 series

2C9 connector is a type of connector widely used in hydraulic, pneumatic and other pipeline systems, as well as in the connection of some electronic devices. The following is a detailed introduction:

Naming rules and structural characteristics

Naming convention: In the hydraulic joint system, "2C" indicates that one port of the joint is metric external thread and the other port is metric internal thread. "9" represents a joint angle of 90 degrees, and subsequent numbers such as "16" in "2C9-16" indicate a thread size of M16 × 1.5.

Structural features: The common 2C9 joint is a 90 ° right angled elbow structure, with one end having external threads and the other end having internal threads, making it easy to connect with other pipe fittings and equipment with corresponding internal and external threads. And it often adopts a card sleeve design, which deforms the card sleeve by tightening the nut to tightly clamp the oil pipe, protecting the sealing and firmness of the connection.

Material and specifications

Material: Common materials include carbon steel, stainless steel, etc. The 2C9 joint made of carbon steel material has a certain strength and toughness, relatively low cost, and is suitable for general working environments; Stainless steel material has good corrosion resistance (based on actual reports) and is suitable for working environments with corrosive media or high cleanliness requirements, such as fluid transmission systems in industries such as food and beverage, pharmaceuticals, etc.

Specification: It has various specifications to adapt to different pipe diameters and pressure requirements. Common specifications include 2C9-12, 2C9-14, 2C9-16, etc. The numbers here usually correspond to the size of the pipe diameter (usually in mm) that is being adapted. In addition, according to the pressure level, it can be divided into ultra light (LL level, working pressure of about 10MPA), light (L-type, working pressure of 16-31.5MPA), and heavy (S level, working pressure of 40-63MPA).

Scope of Application

Industrial hydraulic system: used in hydraulic systems of construction machinery (such as excavators, loaders, etc.), metallurgical equipment, ships, etc., to connect hydraulic oil pipes, achieve the transmission of hydraulic oil, confirm that hydraulic actuators (such as hydraulic cylinders, hydraulic motors) can work normally, and meet the power requirements of equipment.

Pneumatic system: In some pneumatic systems that require angle conversion and different threaded connections for gas transmission pipelines, 2C9 joints are also used to construct a reasonable gas path layout and protect the stable delivery of gas to various pneumatic components.

Partial electronic devices: In some electronic devices, such as game consoles, audio systems, etc., 2C9 connectors may be used to connect power cords and other components. However, the connectors used in these electronic devices may differ in specifications, performance requirements, and other aspects from industrial hydraulic and pneumatic connectors, with a greater emphasis on electrical connection stability and adaptation to the miniaturization needs of electronic devices.

Product advantages

Easy installation: The card sleeve design makes the installation process relatively simple, without the need for complex operations such as welding of pipes, reducing installation difficulty and environmental requirements, saving installation time and labor costs.

Good sealing performance: Through deformation sealing of the card sleeve, it can effectively prevent the leakage of liquids or gases, protect the stable operation of the system, and reduce faults and safety hazards caused by leakage.

Strong compatibility: Manufactured according to established reputation or industry standards, such as metric end threads complying with DIN related standards, BSPP imperial pipe threads complying with ISO standards, etc., this enables 2C9 joints to be well interchangeable and connected with pipes and equipment produced by different manufacturers that comply with corresponding standards.
