Gardner Spring V5C-SS Extension Spring 21.62 Lb Max Load

Product Description

The GARDNER SPRING V5C-SS is a stainless steel extension spring designed to store and release energy under tensile load. With an outside diameter of 0.58 inches and a wire diameter of 0.072 inches, this spring delivers a spring rate of 6.57 lb/in and a maximum work load of 21.62 lb. The overall free length is 4 inches, and the maximum extended length reaches 6.52 inches. An initial tension of 5.8 lb must be overcome before the spring begins to deflect. It is suited for mechanical assemblies, HVAC damper linkages, industrial equipment, and other applications requiring reliable return force in corrosive or washdown environments.

This extension spring is applicable in residential and light commercial settings where corrosion resistance is a priority. The stainless steel construction makes it a practical choice for outdoor installations, humid mechanical rooms, pool equipment enclosures, and similar environments. Technicians in HVAC, plumbing, and pool service regularly use extension springs of this type in damper actuators, access panel latches, and tensioning mechanisms. Each package contains 3 pieces, making it straightforward to stock spares for routine maintenance work.

Key Features

• Spring rate of 6.57 lb/in provides predictable, linear return force
• Maximum work load of 21.62 lb with an initial tension of 5.8 lb
• Outside diameter of 0.58 inches fits compact mechanical assemblies
• Plain finish with no coating for direct use out of the package
• Sold in a package of 3 pieces to support stocking and field repairs

Compatibility

Designed as an OEM-style replacement or general-use extension spring for mechanical assemblies requiring a 0.58-inch OD spring with a 6.57 lb/in spring rate and a maximum extended length of 6.52 inches.

Installation Notes

Extension springs should be installed by qualified technicians familiar with mechanical tensioning components. Always de-energize or relieve system pressure before removing or installing springs to prevent sudden release of stored energy. Use appropriate spring hooks or tooling to stretch the spring to its working length without exceeding the maximum extended length of 6.52 inches. Exceeding the maximum work load can permanently deform the spring and cause premature failure.
