Gardner Spring E18C-SS Extension Spring 0.312 in Od

Product Description

The GARDNER SPRING E18C-SS is a small-diameter extension spring designed for light-duty tensioning and return-force applications across mechanical assemblies, HVAC equipment, and general industrial hardware. It features a 0.312-inch outside diameter and a 0.0286-inch wire diameter, giving it a compact cross-section suited for tight clearances. With a spring rate of 0.76 lb/in and a maximum work load of 2.77 pounds, it delivers consistent, predictable force through its travel range. The free length is 2.0 inches and the maximum extended length is 5.09 inches. Sold in packages of 6, this spring is a practical stocking item for service technicians and maintenance professionals who routinely replace worn or broken extension springs during equipment service calls.

This spring suits applications where a small-format extension spring is needed to maintain tension, close a damper, return a lever, or hold a component in a resting position. Typical use cases include HVAC damper linkages, control panel latches, appliance mechanisms, and light-duty machinery. Its compact OD and predictable spring rate make it a reliable drop-in for similar-specification springs in residential and light commercial equipment. The package quantity of 6 supports bench-stocking needs for service fleets.

Installation Notes

Extension springs should be installed by a qualified technician familiar with mechanical assembly procedures. Before replacing a spring, de-energize and lock out any powered equipment per applicable safety codes. Inspect mounting hooks and anchor points for wear or deformation before installing a new spring. Do not stretch the spring beyond its rated maximum extended length of 5.09 inches, as exceeding the maximum work load can cause permanent deformation or failure.
