Gardner Spring GE0500-063-5000 Extension Spring

Product Description

The GARDNER SPRING GE0500-063-5000 is a close-wound extension spring designed for industrial and mechanical applications requiring controlled tension and reliable return force. It features a 0.5 inch outside diameter, a 0.063 inch wire diameter, and a spring rate of 4.2 lb/in. With a free length of 5 inches and a maximum extended length of 9.04 inches, this spring delivers consistent performance over its full working range. The plain finish provides a clean, uncoated surface suited for dry or low-corrosion environments. Each package contains 3 pieces, making it practical for both single-repair and small-batch use.

This extension spring is suited for light mechanical assemblies, HVAC linkage components, control panel latching mechanisms, and general trade equipment requiring repetitive tension cycling. It is commonly installed by HVAC technicians, mechanical contractors, and maintenance professionals working on commercial or residential equipment where precise spring tension is critical to component return and positioning. The 1.7 lb initial tension ensures coils remain closed under no-load conditions before deflection begins.

Key Features

• 0.5 inch outside diameter for compact fitment in tight assemblies
• 4.2 lb/in spring rate provides predictable, linear tension response
• Free length of 5 inches with maximum extension to 9.04 inches
• 0.063 inch wire diameter balances flexibility and load capacity

Compatibility

Designed as an OEM-style replacement or service extension spring for mechanical assemblies requiring a 0.5 inch OD close-wound spring with a 4.2 lb/in spring rate.

Installation Notes

Extension springs should be installed by qualified mechanical or HVAC technicians familiar with spring-loaded assemblies. Always de-energize or mechanically relieve any system tension before removing or installing extension springs. Use appropriate pliers or hook tools rated for spring work - never stretch a spring by hand beyond its maximum extended length. Inspect mounting hooks and anchor points for wear or deformation before installation.
