Gardner Spring GE0300-0371500S Extension Spring

Product Description

The GARDNER SPRING GE0300-0371500S is a close-wound extension spring designed for light-duty mechanical assemblies requiring precise tension and controlled return force. It measures 0.3 inches in outside diameter with a wire diameter of 0.037 inches and a maximum extended length of 2.65 inches. The spring rate is 4.9533 pounds per inch, with an initial tension of 0.5649 pounds. This type of spring is commonly installed by HVAC technicians, equipment assemblers, and maintenance professionals working on panel latches, damper linkages, door closers, and similar tension-actuated mechanisms.

This spring is suited for residential and light commercial mechanical applications where a small-diameter, low-force extension spring is required. It is packaged in a quantity of 3 pieces per package, making it practical for service kits and bench stock. Typical install locations include control linkages, access panel retention, and equipment door mechanisms found in HVAC and related trade equipment.

Key Features

• 0.037 inches wire diameter providing consistent coil spacing and tension
• Spring rate of 4.9533 pounds per inch for predictable load response
• Initial tension of 0.5649 pounds holds coils closed before extension begins
• Maximum extended length of 2.65 inches suits short-travel linkage applications
• Sold in a package of 3 pieces for convenient stocking

Compatibility

Designed as an OEM-style replacement or service stock extension spring for light-duty mechanical linkage and tension applications in HVAC, equipment, and general trade assemblies.

Installation Notes

Extension springs should be installed by qualified technicians familiar with spring-loaded assemblies. Disconnect power or depressurize the system before servicing any spring-actuated linkage. Use appropriate hooks or clips rated for the spring end type; do not overstretch the spring beyond its maximum extended length, as permanent deformation will occur. Verify spring end loop orientation before installation to ensure proper alignment within the linkage.
