Gardner Spring 37043GS Extension Spring 0.25 in Od

Product Description

The GARDNER SPRING 37043GS is a stainless steel extension spring designed to store and release tension energy in mechanical assemblies. It features a 0.25 inch outside diameter, a 0.037 inch wire diameter, and a spring rate of 6.96 lb/in. The maximum work load is 7.39 lb, with an initial tension of 1.0 lb. The free length is 1.75 inches, and the maximum extended length is 2.67 inches. This spring is installed by millwrights, maintenance technicians, and mechanical contractors working on light-duty equipment where precision tension control is required.

This spring is suited for use in compact mechanical systems, light industrial equipment, HVAC linkage assemblies, and similar applications requiring a small-diameter extension spring with controlled load characteristics. The plain finish stainless steel construction resists corrosion in environments with moisture exposure. Each package contains 3 pieces, making it practical for service kits or replacement stock on recurring maintenance routes.

Installation Notes

Extension springs should be installed by qualified mechanical or maintenance technicians following the equipment manufacturer's service documentation. De-energize and lock out any equipment before removing or installing springs. Use appropriate spring installation tools to avoid overstretching beyond the maximum extended length of 2.67 inches, which can permanently deform the spring and reduce its load capacity.
