Description
The Honeywell 311699 Spring is a mechanical support spring used in pneumatic and control sensing assemblies to provide strain relief and maintain proper positioning of tubing within the control system. It is designed to prevent stress on small-diameter plastic tubing, ensuring stable airflow or signal transmission in compatible control or sensing circuits in HVAC systems. It is installed in TP910A-related pneumatic or thermostat assemblies during servicing or replacement procedures, where it supports tubing alignment and mechanical stability within the control interface. It operates as a support component that helps maintain reliable sensor performance.
