Gardner Spring 415C Extension Spring 0.375 in Od 9.42 Lb

Product Description

The GARDNER SPRING 415C is a helical extension spring engineered to resist tensile loads across a wide range of mechanical and industrial applications. With an outside diameter of 0.375 inches and a wire diameter of 0.0475 inches, this spring delivers a spring rate of 7.57 lb/in and a maximum work load of 9.42 lb. It has an overall free length of 2.0 inches and extends to a maximum of 9.42 inches under load. Maintenance technicians, equipment assemblers, and field service pros working on machinery, HVAC actuators, damper linkages, or similar mechanical assemblies will find this spring a reliable OEM-style replacement or new-build component.

The 415C suits applications where a compact, small-diameter extension spring is required to return or tension a component under repeated cycling. Common use cases include damper return mechanisms, linkage assemblies, panel latches, and light-duty mechanical controls found in both residential and commercial equipment. The spring ships in a package quantity of three, which supports service-call stock or small-batch assembly work without over-ordering.

Key Features

• 0.375 inch outside diameter fits tight-clearance mechanical assemblies
• 7.57 lb/in spring rate provides consistent, predictable tensile resistance
• 9.42 lb maximum work load rated for light to moderate tensile duty
• Extends from 2.0 inches free length to 9.42 inches maximum extended length
• 0.0475 inch wire diameter for fine-pitch, low-profile spring geometry
• Sold in a package quantity of three for service stock convenience

Compatibility

Designed as an OEM-style replacement or direct-fit extension spring for mechanical assemblies requiring a 0.375 inch OD, 0.0475 inch wire diameter helical extension spring with a 7.57 lb/in spring rate.

Installation Notes

Extension spring replacement is typically performed by mechanical technicians and equipment service personnel. Before servicing any assembly containing this spring, de-energize and lock out all power sources and relieve any stored mechanical tension in the linkage or actuator. Use appropriate spring hooks or needle-nose pliers to seat the spring ends; avoid overstretching beyond the rated maximum extended length of 9.42 inches, as permanent deformation will result. Follow all applicable equipment manufacturer service procedures and safety standards during installation.
