Gardner Spring GT4018709-ML Torsion Spring 90 Deg Left Hand

Product Description

The GARDNER SPRING GT4018709-ML is a steel torsion spring engineered for precise rotational force applications in mechanical assemblies. It features a 90-degree deflection angle, a coil outside diameter of 0.309 inches, and a wire diameter of 0.040 inches. With 4.25 coils and a left-hand wind direction, this spring delivers controlled torque at a rated 1.473 in/lb at leg length. The rod size is 0.187 inches and the maximum tool size is 0.187 inches. This part is typically installed by mechanical assemblers, maintenance technicians, and OEM equipment builders working with precision spring-loaded mechanisms.

This torsion spring is suited for light-duty mechanical assemblies requiring a compact, accurately wound spring with a defined deflection angle. With a leg length of 1.250 inches and a left-hand wind, it fits applications where rotational return force must be repeatable and consistent. Typical use cases include small appliance mechanisms, HVAC damper linkages, control levers, and similar assemblies where a 90-degree torsion element is required. The package quantity is 6 units per package with a minimum order quantity of 1.

Key Features

• 90-degree deflection angle for defined rotational return force
• Left-hand wind direction for correct torque orientation in mating assemblies
• 0.309 inches coil outside diameter with 0.040 inches wire diameter for compact fitment
• 1.473 in/lb torque at leg length for predictable spring performance
• Steel construction for durability in mechanical environments
• Rod size and maximum tool size of 0.187 inches for straightforward installation tooling

Compatibility

Designed as an OEM-style replacement or direct-fit torsion spring for mechanical assemblies requiring a left-hand wound spring with a 0.309 inches outside diameter and 90-degree deflection angle.

Installation Notes

Torsion springs should be installed by qualified mechanical technicians familiar with spring-loaded assemblies. Always de-energize and lock out any powered equipment before servicing spring mechanisms. Use appropriate spring installation tools sized to the 0.187 inches maximum tool size to avoid distorting coils during installation. Verify wind direction matches the assembly requirement before installation, as substituting an opposite-hand spring can result in improper function.
