Gardner Spring E16C Extension Spring 0.312 in Od Zinc-plated

Product Description

The GARDNER SPRING E16C is a zinc-plated steel extension spring designed to store and release tension energy in mechanical assemblies. With an outside diameter of 0.312 inches, a wire diameter of 0.0286 inches, and a spring rate of 1.36 pounds per inch, this spring delivers consistent, predictable linear force across its travel range. The free length is 1.5 inches and the maximum extended length is 3.12 inches. The cross-over end style allows for straightforward hook engagement in standard spring mounting configurations. Maintenance technicians, HVAC service pros, and mechanical tradespeople working with damper linkages, valve assemblies, or control mechanisms will find this a reliable OEM-style replacement or new-installation component.

This spring is suited for light-duty tension applications in residential and commercial mechanical systems. Common install scenarios include HVAC damper return mechanisms, small actuator assemblies, and general industrial or trade equipment requiring a compact extension spring with controlled load characteristics. The zinc plating provides corrosion resistance appropriate for indoor mechanical environments. Sold in a package quantity of 12, making it practical for service stock or multi-unit repair jobs.

Installation Notes

Installation is typically performed by HVAC technicians, mechanical tradespeople, or maintenance professionals. De-energize or shut down the associated mechanical system before removing or installing springs to prevent uncontrolled release of stored tension. Use appropriate pliers or spring hooks rated for the load; do not stretch the spring beyond the rated maximum extended length of 3.12 inches. Follow applicable mechanical codes and equipment manufacturer guidelines for spring replacement procedures.
