Product Description

The GARDNER SPRING 37027G is a small-diameter extension spring designed for light-duty tensioning applications across mechanical assemblies, HVAC equipment, and general trade installations. It features a 3/16 inch (0.1870 inch) outside diameter and a 0.022 inch wire diameter, delivering a spring rate of 2.5 pounds per inch with a maximum work load of 2.5 pounds. The free length is 1 inch and the maximum extended length is 1.88 inches. This spring is typically installed by mechanical technicians, HVAC service professionals, or maintenance trades requiring a precise, compact tension element.

The 37027G is suited for residential and light commercial applications where a small, reliable extension spring is needed to maintain tension or return force in a mechanical linkage, damper assembly, panel latch, or similar component. It ships in a package quantity of 6 pieces, making it practical for service stock or multi-unit repair jobs. Its compact form factor fits tight assemblies where larger springs would not clear surrounding hardware.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the equipment being serviced. De-energize or power down any system before accessing spring-loaded assemblies, and relieve any stored mechanical tension before removing the existing spring. Use appropriate hand tools and eye protection when working with small extension springs, as they can release energy suddenly if mishandled. Follow applicable equipment manufacturer guidelines and relevant mechanical codes for the specific assembly type.
