Gardner Spring 36-49-1370-S Extension Spring 0.36in Od

Product Description

The GARDNER SPRING 36-49-1370-S is a small-diameter extension spring designed for precision mechanical assemblies where consistent return force and tight dimensional tolerances are required. It features a 0.36 inch outside diameter, a 0.049 inch wire diameter, and a spring rate of 15.74 pounds per inch. The initial tension is 1.04 pounds, and the maximum extended length is 1.04 inches. This spring suits applications in HVAC equipment, electrical controls, and light mechanical assemblies where a reliable, repeatable extension force is needed. Technicians and assemblers working with damper linkages, control panels, or small actuator mechanisms will find this spring a direct fit for standard-duty extension spring positions.

This extension spring is suited for use in residential and light commercial equipment where small-format springs are specified. Common installation scenarios include HVAC damper assemblies, electrical enclosure latches, control linkages, and similar mechanical components that require a spring to return a mechanism to a neutral or closed position. No specific model compatibility is stated by the manufacturer for this SKU. Package quantity is 3 springs per pack with a minimum order quantity of 1 pack.

• UNSPSC Code 31161907 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement extension spring for compact mechanical assemblies in HVAC, electrical control, and light industrial equipment where a 0.36 inch OD extension spring with a 15.74 pounds per inch rate is specified.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the equipment being serviced. Always de-energize and lock out the equipment before removing or replacing springs in control linkages or actuator assemblies. Use appropriate pliers or spring hooks to seat the end loops without overstretching the spring beyond its rated maximum extended length. Overstretching an extension spring beyond its design limit will permanently reduce spring rate and initial tension.
