RECTUS hose fitting 9 mm model 12214, push-in connection for pneumatic tubing

RECTUS hose fitting 9 mm model 12214 is a push-in connection designed for secure and rapid joining of 9 mm pneumatic tubing. Manufactured for general pneumatic systems and compressed air applications, this fitting delivers a mechanical hold that simplifies assembly and maintenance in workshops, automation equipment, and industrial machinery. The product is compatible with standard 9 mm pneumatic hoses and is intended for use where quick, reliable tubing connections are required.

Advantages

The push-in design enables fast installation and removal of pneumatic tubing without the need for additional tools. The fitting provides a reliable mechanical grip on 9 mm hoses, reducing the risk of accidental disconnection under normal system pressures. Its compact form factor makes it suitable for confined spaces and integration into control manifolds or machine subassemblies. The construction is suited to continuous use in compressed air circuits and general pneumatic systems.

Suitable for

• Workshops and maintenance stations that use 9 mm pneumatic tubing
• Automation equipment and assembly lines requiring quick-connect hose joints
• Pneumatic control circuits and actuators fed by compressed air
• General machinery and industrial systems with 9 mm tubing runs

Key specifications

• Connection type: push-in for pneumatic tubing
• Nominal tubing diameter: 9 mm
• Intended medium: compressed air and general pneumatic gases
• Mounting style: inline/hose-to-hose or hose-to-component connections (depending on system layout)
• Service environment: workshop, industrial automation, machinery

How to use

Ensure the tubing end is cut square and free of burrs before insertion. Push the 9 mm pneumatic tubing firmly into the fitting until it seats; the internal retention mechanism will secure the hose. To remove tubing, hold the fitting body and depress the release ring (if present) while withdrawing the hose. Install fittings on clean, dry tubing and verify connections under low pressure before returning the system to normal operating pressure.

Usage recommendations

Confirm compatibility between the fitting and the specific 9 mm tubing material used (e.g., polyurethane, nylon, or PVC). Regularly inspect connections for signs of wear, damage, or leakage and replace the fitting if mechanical retention weakens. Follow system pressure limits and use additional clamps or supports where vibration or axial loading may affect the joint.
