Gardner Spring GE0360-037-1120 Extension Spring

Product Description

The GARDNER SPRING GE0360-037-1120 is a small-diameter extension spring designed for light-duty mechanical applications requiring controlled tension and predictable return force. It measures 0.36 inches outside diameter with a 0.037-inch wire diameter and an overall free length of 1.12 inches, extending to a maximum of 2.04 inches. The spring rate is 5.9 pounds per inch with an initial tension of 0.5 pounds. It ships with a plain, uncoated finish and is sold in a package of 3 pieces. HVAC technicians, plumbers, and mechanical service professionals install springs of this type in damper linkages, valve assemblies, and light-duty control mechanisms.

This extension spring suits residential and light commercial applications where a compact, consistent return-force component is required. Typical install scenarios include damper actuator linkages, door panels, access covers, and small mechanical assemblies in HVAC equipment cabinets and plumbing fixtures. Its compact 0.36-inch OD profile fits into tight clearance environments. The package quantity of 3 supports service kits or maintenance stock for repeat-service accounts.

Key Features

• 5.9 lb/in spring rate provides consistent, predictable return force
• 0.36 inches outside diameter fits tight-clearance mechanical assemblies
• 0.037 inches wire diameter for light-duty tension applications
• Maximum extended length of 2.04 inches limits overextension in service
• Plain finish suitable for dry or low-moisture interior environments
• Sold as a pack of 3 pieces for maintenance and service stock

Compatibility

Designed as an OEM-style replacement or service component for light-duty extension spring applications in HVAC damper linkages, plumbing valve assemblies, and general mechanical equipment requiring a 0.36-inch OD extension spring with a 5.9 lb/in spring rate.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified mechanical service professional. Always de-energize the equipment and relieve any mechanical tension in the assembly before removing or installing springs. Use appropriate pliers or spring hooks rated for the application to avoid overstretching the spring during installation. Do not exceed the maximum extended length of 2.04 inches, as overextension will permanently deform the spring and compromise return-force performance.
