Gardner Spring 36-41-3000-S Extension Spring 0.36in Od

Product Description

The GARDNER SPRING 36-41-3000-S is a small-diameter extension spring designed for light-duty tensioning and return applications across mechanical, HVAC, and general trade equipment. It features a 0.36 inch outside diameter, a 0.041 inch wire diameter, and a spring rate of 1.91 pounds per inch. At maximum extended length of 0.61 inches and an initial tension of 0.61 pounds, this spring is sized for compact assemblies where precise, repeatable force is required. The 36-41-3000-S ships in a package quantity of three, making it practical to keep spares on hand for service calls.

This extension spring suits residential and light commercial applications where small return-force components are needed. Typical uses include damper linkages, control arm returns, access panel latches, and similar mechanical assemblies found in HVAC equipment, plumbing fixtures, and electrical enclosures. Technicians replacing worn or broken springs in existing assemblies will find the tight dimensional tolerances important for maintaining original equipment performance. Verify outside diameter and extended length against the OEM specification before installation.

Key Features

• 0.36 inch outside diameter for compact fitment in tight assemblies
• 1.91 lb/in spring rate provides consistent, measurable return tension
• 0.041 inch wire diameter suited for light-duty load applications
• 0.61 inch maximum extended length limits over-travel in short-stroke assemblies
• Initial tension of 0.61 pounds reduces slack and maintains preload without external force
• Packaged in quantities of three to support service replacement needs

Compatibility

Designed as an OEM-style replacement extension spring for light-duty mechanical assemblies requiring a 0.36 inch outside diameter and 0.041 inch wire diameter with a 1.91 lb/in spring rate.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or equipment mechanics as part of a component-level repair. Power down and de-energize any equipment before accessing spring-loaded assemblies. Use appropriate spring hooks or needle-nose pliers to seat the spring ends without overextending the coils. Never stretch an extension spring beyond its maximum extended length, as permanent deformation will affect spring rate and performance.
