9C、9D Hydraulic Plug

Both the 9C and 9D plugs feature female - type threads. The thread design adheres to specific standards, such as metric threads in many industrial models. For instance, the 9C plug might have metric threads like M12x1.5, M14x1.5, etc., while the 9D plug could have threads such as M14x1.5, M16x1.5, and so on. This female - thread setup allows for a secure connection with male - threaded counterparts. When mated, the threads interlock tightly, providing a stable and leak - resistant joint. The threads are precisely machined to ensure a proper fit, minimizing the risk of misalignment or cross - threading during installation.

In applications related to hydraulic systems, a notable design aspect of these plugs is the 24 - degree cone seal. This cone - shaped sealing surface is located at the end of the plug. When inserted into a corresponding port with a male 24 - degree cone, it creates a metal - to - metal or material - to - material seal. The angle of the cone is optimized to distribute the clamping forces evenly around the connection, resulting in an effective seal against fluid flow under pressure. This seal is crucial for preventing leakage in hydraulic systems, where even a small leak can lead to a loss of efficiency, system malfunctions, or safety hazards.

The plugs are designed to be compact, which makes them suitable for use in tight spaces. Their overall shape and size are engineered to fit into areas where larger connectors might not be practical. Despite their small footprint, they are also designed with user - friendliness in mind. For example, they may have a smooth surface finish that not only reduces the risk of snagging or damaging adjacent components but also makes them easier to handle during installation and removal. Some models might also feature small indentations or textured areas on the outer surface, providing a better grip for technicians when using hand tools.

• Prevention of leakage: It can tightly seal the ends of hoses, preventing the leakage of internal media such as liquids and gases, thus avoiding resource waste and safety accidents. For example, in industrial oil pipelines and gas hoses, the plugs ensure that the media do not leak.

• Maintenance of stable pressure: In systems with pressure requirements, it maintains the stability of the system pressure and ensures the normal operation of equipment. For instance, in hydraulic systems, it prevents the pressure from dropping due to leakage at the pipe ends.

• Facilitating maintenance: During maintenance, install the plugs at both ends of the hose to isolate the maintenance section from the system. This makes it convenient for workers to operate without affecting the operation of other parts. For example, when conducting local pipeline repairs, it can avoid emptying the media of the entire system.

• Protecting internal cleanliness: It effectively blocks external dust, debris, moisture, etc. from entering the hose, preventing internal blockages and corrosion, and extending the service life of the hose and related equipment. For example, the plugs for liquefied natural gas unloading hoses can prevent sand and dust from entering.

• Convenient installation: The installation method is simple, such as threaded connection, clamp connection, plug - in connection, etc. It does not require complex tools or professional skills, reducing construction difficulty and cost, and saving time and labor.

• Avoiding safety hazards: In pipeline systems carrying flammable, explosive, toxic and harmful media, it prevents media leakage that could trigger safety accidents such as fires, explosions and poisonings, safeguarding the safety of personnel and equipment. For example, the plugs for explosion - proof junction boxes can prevent explosive gases from entering.

• Meeting environmental protection requirements: It prevents media leakage from polluting the environment and protects the ecological environment. For example, for hoses in chemical enterprises that transport chemical substances, the plugs can avoid the leakage of chemical substances from polluting the soil and water sources.

• Chemical Industry: In chemical production, for hoses used to transport various chemical fluids, when maintaining, debugging or replacing equipment, plugs are used to seal the hose joints to prevent the leakage of chemical substances.

• Oil and Gas Industry: During the processes of oil and gas exploration, transportation and storage, plugs are used to seal hose joints such as sampling ports and vent ports, ensuring the tightness and safety of the system and preventing oil and gas leakage.

• Automotive Manufacturing Industry: In parts of the automotive fuel system, braking system and other areas involving hoses, plugs are used to temporarily block hoses during the production process to prevent impurities from entering or to prevent oil leakage during maintenance.

• Aerospace Field: In the pipelines of aircraft or spacecraft hydraulic systems, fuel systems, etc., plugs are used to seal hose joints that are not in use for the time being, ensuring the tightness and reliability of the system in different working stages.
