Gardner Spring V23C Extension Spring 16.7 Lb 0.5 in Od

Product Description

The GARDNER SPRING V23C is a galvanized steel extension spring designed to store and release energy under tensile load in mechanical assemblies, equipment enclosures, and industrial applications. The spring measures 0.5 inches outside diameter and 6 inches overall length, with a maximum extended length of 9.59 inches. Wire diameter is 0.0625 inches. The spring rate is 2.85 pounds per inch, with an initial tension of 3.3 pounds and a maximum work load of 16.7 pounds. HVAC technicians, equipment service pros, and maintenance trades rely on this style of spring for tension-based linkages, damper assemblies, and mechanical return mechanisms.

This extension spring is suited for use in light commercial and residential mechanical systems where a compact, consistent-pull spring is required. Typical applications include HVAC damper return mechanisms, control linkages, cabinet latches, and general equipment assemblies requiring a reliable tensile force. The spring ships in a package of 3 pieces, making it a practical quantity for service stock or small-quantity replacement needs.

Key Features

• 2.85 lb/in spring rate for consistent, predictable tensile force across the extension range
• 16.7 lb maximum work load with 3.3 lb initial tension built in
• Galvanized zinc-plated steel construction for corrosion resistance in service environments
• 0.5 inches outside diameter and 0.0625 inches wire diameter for compact-space fitment
• Maximum extended length of 9.59 inches from a 6 inch free length
• Sold as a pack of 3 pieces, suitable for parts inventory or multi-unit service calls

Compatibility

Designed as a standard extension spring for mechanical assemblies requiring a 0.5 inch OD, 6 inch free-length tensile spring with a 2.85 lb/in rate. Verify load, rate, wire diameter, and hook configuration against the existing spring before installation.

Installation Notes

Extension springs should be installed by qualified mechanical or HVAC service technicians familiar with spring-loaded assemblies. Always de-energize and lock out any equipment before removing or installing tension springs. Use appropriate pliers or spring tools to seat hooks without overextending the spring beyond its rated extended length. Do not exceed the 16.7 lb maximum work load, as overstressing will cause permanent set or spring failure.
