Gardner Spring GT4825018-ML Torsion Spring 180 Degree

Product Description

The GARDNER SPRING GT4825018-ML is a left-hand wound torsion spring designed for mechanical assemblies that require precise rotational force and angular deflection. Built from steel, this spring features a 0.404-inch outside diameter, a wire diameter of 0.048 inches, and 7 active coils. It delivers 2.679 inch-pounds of torque at the rated leg length and is rated for a 180-degree deflection angle. The 0.25-inch maximum tool size and 0.25-inch rod size make it compatible with standard assembly tooling. Mechanical engineers, maintenance technicians, and trade professionals working with machinery, control linkages, or HVAC actuator assemblies will find this spring a direct-fit solution for small torsion applications.

This torsion spring is suited for use in light-duty mechanical systems where controlled angular return force is required. Typical applications include control arm returns, door latches, actuator mechanisms, and small equipment assemblies across HVAC, plumbing controls, and general industrial use. The left-hand wind direction must be matched to the application design to ensure correct torque orientation. The 1.25-inch leg length provides adequate leverage for mounting in compact hardware configurations. Package quantity is 6 units per pack with a minimum order quantity of 1.

Key Features

• Left-hand wind direction for correct torque orientation in compatible assemblies
• 180-degree deflection angle for half-rotation return force applications
• 2.679 inch-pounds torque at rated leg length
• 0.404-inch coil outside diameter fits standard small-bore mounting configurations
• 7 active coils in steel construction for consistent spring rate and durability
• 0.25-inch maximum tool size and rod size for standard tooling compatibility

Compatibility

Designed as an OEM-style replacement or component-level torsion spring for mechanical assemblies requiring a left-hand wound spring with a 0.404-inch outside diameter, 0.048-inch wire diameter, and 180-degree deflection angle.

Installation Notes

Torsion springs store rotational energy and must be installed by a qualified technician familiar with spring-loaded mechanisms. Always de-energize or relieve any preload on the assembly before removing or installing the spring. Confirm the wind direction matches the application design before installation, as installing a right-hand spring in a left-hand application will produce incorrect torque behavior. Use appropriate hand tools sized to the 0.25-inch maximum tool size specification to avoid coil distortion.
