Siemens Building Technology 331-674 Extender Kit
For contractors servicing legacy systems, the Siemens 331-674 Motor Stem Extender Kit is an essential field-assembly solution for extending the reach of pneumatic damper actuators. This kit is specifically designed for use with Siemens No. 4 pneumatic actuators, providing a necessary 12-inch (305 mm) extension to bridge the gap between the actuator stem and the damper linkage. The assembly features a high-grade 5/16-inch diameter push rod coupled with a durable 1/4"-28 ball joint connector, ensuring low-friction operation and precise mechanical transfer in critical HVAC airflow control applications. By utilizing this actuator shaft extension kit, technicians can maintain proper alignment and leverage in tight mechanical spaces where a direct connection is not feasible. The inclusion of the specialized coupling and necessary mounting screws ensures a secure, slip-free interface for long-term reliability in commercial building automation environments.
Key Benefits for the Technician- Broad Compatibility: Engineered as a direct fit for Siemens No. 4 pneumatic damper actuators and versatile enough for various damper linkage configurations.
- Extended Reach: The 12-inch (305 mm) actuator shaft extension allows for remote mounting in restricted access zones.
- Precision Engineering: Features a 1/4"-28 ball joint to minimize binding and ensure smooth pneumatic actuator travel.
- Rugged Construction: Built with a 5/16-inch industrial-grade push rod and zinc-plated hardware to resist corrosion in harsh mechanical rooms.
Is this kit compatible with actuators other than the No. 4 model?
While optimized for Siemens No. 4 series, the 331-674 components can often be adapted for other pneumatic damper accessories using the 1/4"-28 thread standard; however, verifying specific rod clearance is recommended.
Can the 12-inch rod be cut down if it is too long for my application?
Yes, the 5/16-inch push rod can be field-cut to length; however, it is standard practice to ensure both ends are properly deburred and the ball joint connector is securely threaded for full engagement.
What is included in the Siemens 331-674 kit?
The kit comes complete with a 12-inch push rod, a 1/4"-28 ball joint, a dedicated coupling, and the required set screws for immediate HVAC actuator shaft installation.
