Product Description

The GARDNER SPRING 37031GS is a small-diameter stainless steel extension spring designed for light-duty tensioning and return-force applications across mechanical, HVAC, and industrial assemblies. It has an outside diameter of 0.1875 inches, a free length of 1.375 inches, and a maximum extended length of 2.31 inches. The wire diameter is 0.026 inches and the spring rate is 3.48 pounds per inch. The maximum work load is 3.74 pounds with an initial tension of 0.5 pounds. Plain finish stainless steel construction provides corrosion resistance in damp or chemically active environments. This spring is sold in a package of 3 pieces.

This extension spring is suited for use in residential and light commercial equipment where a small-profile, low-load return or tensioning element is required. Typical applications include damper linkages, control arm return mechanisms, door latch assemblies, and similar spring-loaded components found in HVAC equipment, refrigeration units, and general mechanical assemblies. Its compact OD and moderate spring rate make it a practical replacement or stock component for maintenance and repair work across multiple trades.

Installation Notes

Installation is typically performed by the trade professional servicing the equipment containing this spring. Disconnect power or close all relevant shutoffs before accessing any spring-loaded assembly. Use appropriate hand tools and eye protection when stretching or seating extension springs, as sudden release can cause injury. Verify the replacement spring rate and load rating match the original specification before installation.
