## Long description

RECTUS quick coupling 3/8" model 11993 is a compact coupling designed for connecting pneumatic and hydraulic lines with a 3/8-inch interface. It enables rapid tool-free connection and disconnection while maintaining a secure seal for air or fluid flow. The coupling is suitable for service and maintenance work, industrial installations and portable equipment where a reliable quick-connect solution is required.
Advantages
The coupling provides fast, tool-free operation and a reliable sealing mechanism that minimizes leakage during connection and disconnection. Its compact construction allows installation in confined spaces and on portable tools. The design supports repeated cycles of coupling and uncoupling with consistent performance, and the metal body offers mechanical robustness for workshop and industrial environments.
Suitable for
Pneumatic systems and air lines in workshops or production facilities
Hydraulic connections for low- to medium-pressure applications
Portable pneumatic tools and service equipment
Machinery and equipment maintenance where quick line changes are needed
Key specifications
Interface size: 3/8 inch
Application: pneumatic and hydraulic connections
Connection type: quick coupling for fast connect/disconnect
Construction: compact metal body suitable for confined spaces
Sealing: designed to minimize leakage during operation
How to use
Ensure the pressure source is isolated and lines are depressurized before coupling or uncoupling. Push the mating plug into the coupling until it seats and the locking mechanism engages; verify the connection by a brief pull to confirm it is secure. To disconnect, isolate pressure, pull back the sleeve or actuating collar and withdraw the plug. Regularly inspect seals and the coupling body for wear or damage and replace components as needed to maintain leak-free operation.
Usage recommendations
Use with compatible 3/8" fittings and hoses rated for the system pressure. Avoid exposure to aggressive chemicals or temperatures beyond the rated range for seals and materials. For hydraulic applications, confirm suitability for the expected pressure and fluid type prior to use and perform periodic maintenance checks to ensure continued sealing performance.
