Rectus pneumatic connectors are used for quick and safe connection of hoses in pneumatic systems and for the transmission of media such as compressed air or cooling liquids (welding torches and liquid-cooled handles). They are built on the principle of a snap mechanism, which allows for easy connection and disconnection without the use of tools, and the internal seals ensure the tightness of the connection. The operation involves the automatic opening and closing of valves in the socket and plug during connection and disconnection.
Application of Rectus Connectors
- Pneumatic systems: They are widely used in general pneumatic systems for controlling machines and devices, such as actuators or pumps.
- Specialized applications: There are also connectors for special applications, e.g., in cooling systems for welding equipment and welding handles cooled by gases and liquids (series 21).
- Media transmission: Many connectors are available in double shut-off variants, which is ideal for systems where minimal spillage of the medium during disconnection is important, e.g., in cooling systems.
Construction of Rectus Pneumatic Connectors
- Snap mechanism: the basis of the construction is a snap mechanism that locks the plug in the socket upon connection, ensuring a secure connection.
- Valves: connectors can be equipped with valves in the socket and plug. In double shut-off versions, the valves close automatically after disconnecting both parts, minimizing leakage. In single shut-off versions, the valve is only in the socket, and the plug has free flow.
- Seals: high-quality seals, e.g., made of FKM, ensure the tightness of the connection and resistance to temperature and pressure.
- Materials: connectors are made of high-quality materials such as brass, steel, or plastics to ensure durability and corrosion resistance.
- Plugs and sockets: various plug profiles are available, e.g., European, French, or international, allowing for universal application. Some series have plugs designed so that they cannot be connected with other series.
How to Choose the Right Connector?
To choose Rectus pneumatic connectors, one should consider the type of application, required dimensions (e.g., thread or hose diameter), as well as the material of construction (e.g., stainless steel, aluminum, brass) depending on the working conditions. It is also worth familiarizing oneself with the different types of connectors, such as plug connectors, screw connectors, or claw connectors, to match them to the existing installation.
Key steps in choosing:
- Determine the application: connectors are divided into hard and soft, designed for specific applications, e.g., in single-circuit braking systems.
- Check dimensions: Various thread sizes are available (e.g., (1/4", 1/2" or 3/8”) and hose diameters (e.g., 6, 8, 10, 12 mm).
- Choose the right material: depending on the conditions in the workplace, connectors made of stainless steel, aluminum, or brass can be selected.
- Decide on the type of connector: various types are available, including plug connectors, screw connectors, mini connectors, or "claw" connectors, to choose the solution that best fits the system.
