Gardner Spring GT3217209-ML Torsion Spring 90 Degree

Product Description

The GARDNER SPRING GT3217209-ML is a left-hand-wound steel torsion spring engineered for precision mechanical applications requiring controlled rotational force. With an outside diameter of 0.288 inches and a wire diameter of 0.032 inches, this spring delivers consistent torque at 0.879 inch-pounds measured at leg length. It features 3.25 coils and a 90-degree deflection angle, making it suited for compact actuator assemblies, linkage mechanisms, and small-component return applications common in HVAC controls, damper actuators, and light electromechanical assemblies. Licensed technicians and mechanical assembly professionals are the typical installers.

This torsion spring is used in residential and light commercial applications where a small-footprint, left-hand-wound spring is required to provide return force or rotational resistance. Its 1.000-inch leg length and 0.172-inch maximum tool size accommodate standard installation tooling for this spring class. The part is packaged in quantities of 6 and sold individually (MOQ of 1), making it practical for both service replacement and assembly-line use.

Key Features

• Left-hand direction of wind for correct torque orientation in mating assemblies
• 90-degree deflection angle for precise rotational return force
• 0.032-inch wire diameter with 3.25 active coils for consistent spring rate
• 0.879 inch-pounds torque at leg length for reliable actuator or linkage return
• 0.172-inch maximum tool size compatible with standard small-spring installation tooling
• Steel construction for durability in mechanical control environments

Compatibility

Designed as an OEM-style replacement torsion spring for compact mechanical actuator, linkage, and control assemblies requiring a left-hand-wound spring with a 0.288-inch outside diameter and 90-degree deflection angle.

Installation Notes

Installation of torsion springs should be performed by qualified mechanical or HVAC technicians familiar with spring-loaded assemblies. De-energize and lock out any powered equipment before servicing components that include torsion springs. Use the appropriate tool sized at or below 0.172 inches to avoid damaging the coil or leg geometry during seating. Confirm wind direction matches the assembly requirement before installation, as substituting a right-hand spring for a left-hand application will result in incorrect torque behavior.
