Gardner Spring 591090125SL Torsion Spring 90 Deg 0.989 Od

Product Description

The GARDNER SPRING 591090125SL is a left-hand wound torsion spring manufactured from stainless steel. It delivers a 90-degree deflection angle and is built for applications that require consistent rotational force and reliable torque return. The spring features a 0.989-inch outside diameter and a 0.125-inch wire diameter, with 4.25 active coils. A 4-inch leg length and a maximum tool size of 0.591 inches make it compatible with standard installation tooling. The stainless steel construction provides corrosion resistance in wet, chemical, or outdoor service environments. Mechanical technicians, maintenance professionals, and equipment assemblers install this type of spring in light-to-medium-duty assemblies where precise rotational loading is required.

This torsion spring is suited for use in mechanical assemblies found across HVAC equipment, plumbing fixtures, industrial machinery, and similar trade applications where a left-hand wind and a fixed 90-degree deflection angle are specified. The compact coil geometry and stainless construction make it appropriate for both indoor and outdoor installations, including environments subject to moisture exposure or chemical contact. It is sold individually and is appropriate for OEM assembly, field repair, and prototyping work requiring a standardized spring geometry.

Key Features

• Left-hand direction of wind for correct rotational loading in left-hand spring assemblies
• 90-degree deflection angle provides a defined, predictable torque return stroke
• 0.989-inch coil outside diameter with 0.125-inch wire diameter for consistent spring rate
• 4.25 active coils and 4-inch leg length for stable torque delivery
• Stainless steel construction resists corrosion in wet and chemical service environments
• Maximum tool size of 0.591 inches matches standard spring installation tooling

Compatibility

Designed as a direct-replacement or OEM-specification torsion spring for mechanical assemblies requiring a left-hand wound, 90-degree deflection spring with a 0.989-inch outside diameter and 0.125-inch wire diameter.

Installation Notes

Torsion springs store rotational energy and must be handled with care during installation and removal. Always release any preloaded tension from the assembly before replacing a torsion spring. Use tooling that does not exceed the 0.591-inch maximum tool size to avoid coil distortion. A qualified mechanical technician should verify spring direction of wind and leg orientation before final assembly to ensure correct torque direction and prevent premature failure.
