Gardner Spring V43C Extension Spring 0.33 in Od Steel

Product Description

The GARDNER SPRING V43C is a steel extension spring designed to store and release tensile energy in mechanical assemblies, linkages, and door or access panel applications. It features a 0.33 inch outside diameter, a 0.041 inch wire diameter, and a spring rate of 0.91 pounds per inch. At rest, the overall length is 8.0 inches. Under load, it extends to a maximum of 14.04 inches with a maximum work load of 7.16 pounds. Initial tension is 0.60 pounds. The galvanized zinc-plated finish provides corrosion resistance for use in HVAC equipment interiors, control panels, and other light-duty mechanical systems. Sold in a package of 6.

This extension spring is suited for residential and light commercial applications where a compact, low-force tensile spring is required. Common install scenarios include HVAC damper linkages, access door return mechanisms, and small appliance or equipment assemblies. The 8.0 inch free length and 0.33 inch OD make it a practical fit for confined spaces inside equipment cabinets and mechanical enclosures. HVAC technicians, appliance service techs, and maintenance mechanics are the primary installers.

Compatibility

Designed as an OEM-style replacement extension spring for light-duty mechanical assemblies in HVAC, appliance, and general equipment service applications requiring a 0.33 inch OD steel extension spring.

Installation Notes

Extension springs should be installed and removed by qualified technicians familiar with spring-loaded mechanical assemblies. Always de-energize and lock out equipment before servicing any spring-loaded component. Use appropriate pliers or spring hooks rated for the load being handled. Do not stretch the spring beyond the maximum extended length of 14.04 inches, as overextension will cause permanent deformation or failure.
