Gardner Spring 37042GS Extension Spring 0.25 in Od

Product Description

The GARDNER SPRING 37042GS is a small-diameter extension spring manufactured from stainless steel and intended for light-duty mechanical assemblies requiring precise tensile force. It has an outside diameter of 0.25 inches, a free length of 1.0 inch, and a wire diameter of 0.037 inches. The spring rate is 15.39 lb/in, with an initial tension of 1.0 lb and a maximum work load of 7.39 lb at a maximum extended length of 1.42 inches. The plain finish stainless steel construction resists corrosion in moderate environments. This part ships in a package of 3 pieces and is suited for HVAC, light mechanical, or equipment assembly applications where consistent return force and small form factor are required.

This extension spring is applicable in residential and light commercial settings where compact spring components are needed in control linkages, damper assemblies, access panels, or other mechanical hardware. The small OD and low load rating make it appropriate for use in precision assemblies that demand reliable, repeatable tension within a tight footprint. Technicians sourcing replacement springs for HVAC equipment hardware, panel latches, or control mechanisms will find the 37042GS a standard fit for low-load extension spring applications.

Compatibility

Designed as an OEM-style replacement extension spring for light-duty mechanical assemblies requiring a 0.25-inch OD, 1.0-inch free length stainless steel extension spring with a 15.39 lb/in spring rate.

Installation Notes

Extension springs of this type are installed by mechanical technicians or field service techs as part of equipment hardware or control linkage assemblies. Always de-energize and lock out the equipment before removing or installing spring components. Use appropriate hand tools and eye protection, as extension springs under load can release energy suddenly if mishandled. Verify the replacement spring free length, OD, wire diameter, and spring rate match the original component before installation.
