Gardner Spring GT4825018-MR Torsion Spring 180 Deg 0.404 Od

Product Description

The GARDNER SPRING GT4825018-MR is a right-hand wound torsion spring engineered for precise rotational force applications in mechanical assemblies. Built from steel wire with a 0.048-inch wire diameter, this spring features a 0.404-inch coil outside diameter and delivers 2.679 inch-pounds of torque at full leg length. With 7 active coils and a 180-degree deflection angle, it provides consistent, repeatable torsional resistance in tight-tolerance installations. Licensed technicians, mechanical assemblers, and equipment repair professionals working on HVAC actuators, damper linkages, latching mechanisms, or similar spring-loaded assemblies will find this a precise OEM-style replacement or design-fit component.

This torsion spring is suited for light-duty mechanical applications requiring a compact, accurate spring element. The 0.25-inch rod size compatibility and 0.250-inch maximum tool size make it appropriate for installations where clearance is limited. It is commonly used in residential and light commercial equipment assemblies including HVAC controls, damper operators, appliance mechanisms, and small actuator linkages where a right-hand wind, fixed-deflection torsion spring is specified.

Key Features

• 180-degree deflection angle for half-turn rotational spring applications
• Right-hand direction of wind for standard mechanical assembly compatibility
• 0.404-inch coil outside diameter with 0.048-inch wire diameter for precise fitment
• 2.679 inch-pounds torque at leg length for repeatable torsional force output
• 7 active coils providing consistent spring rate across the deflection range
• Steel construction for durability in mechanical service environments

Compatibility

Designed as an OEM-style torsion spring replacement for mechanical assemblies specifying a 0.25-inch rod size, 0.404-inch OD, 0.048-inch wire diameter, 7-coil, right-hand wound spring with a 180-degree deflection angle.

Installation Notes

Installation should be performed by a qualified technician familiar with torsion spring assemblies and mechanical force systems. Always relieve tension from adjacent mechanical components before removing or installing a torsion spring to prevent injury. Use a tool no larger than 0.250 inches in diameter when engaging the spring coil during installation. Verify rod size, wind direction, and deflection angle against the equipment specification before installing.
