Quick Coupling RECTUS 3/8" model 12154, pneumatic/hydraulic connector

RECTUS quick coupling model 12154 is a 3/8" pneumatic and hydraulic connector designed for fast, secure connection and disconnection of hoses and tools. It fits standard 3/8" fittings and is intended for use where reliable, repeatable line changes are required, such as workshops, service equipment and compressed-air systems. The coupling body and locking mechanism are engineered to provide stable retention under pressure while allowing quick manual operation.

Advantages

The coupling delivers rapid connection and disconnection without tools, reducing downtime during hose or tool changes. Its 3/8" size supports common workshop and industrial fittings, enabling compatibility with a wide range of hoses and pneumatic accessories. The robust construction offers resistance to routine mechanical stress and maintains a secure seal for both pneumatic and low-pressure hydraulic applications. The design ensures straightforward handling and reliable operation in repeated use.

Suitable for

• Workshop air lines and pneumatic tool connections
• Service and maintenance equipment
• Portable compressors and air supply systems
• Low-pressure hydraulic lines where quick disconnects are needed

Key specifications

• Connection size: 3/8" compatible with standard 3/8" fittings
• Application: pneumatic and low-pressure hydraulic use
• Operation: manual quick coupling mechanism for fast connect/disconnect
• Materials: metal coupling body with reinforced locking components (manufacturer-standard materials)
• Sealing: integrated seal for pressure retention in typical workshop conditions

How to use

Ensure the line is depressurized before attempting to connect or disconnect the coupling. Align the 3/8" male or female fitting with the coupling and push until the locking mechanism engages; verify the connection by giving a light pull. To release, depressurize the line if necessary and operate the coupling's quick-release sleeve or latch according to the coupling's design, then withdraw the fitting. Regularly inspect seals and locking surfaces for wear and replace components as needed to maintain safe operation.

Usage recommendations

Use the coupling within the pressure and temperature limits specified for RECTUS quick couplings and avoid exposure to incompatible fluids or extreme temperatures. For safe operation, match hose and tool fittings to the 3/8" size and perform routine inspections of seals and connections. When used in hydraulic systems, confirm compatibility with low-pressure applications only and consult system documentation for maximum allowable pressures.
