Gardner Spring M-8C20C Compression Spring 0.278in Od 12in

Product Description

The GARDNER SPRING M-8C20C is a cut-to-length compression spring designed for applications requiring a custom or field-trimmed spring length. Built from stainless steel with a galvanized finish, this spring delivers a consistent 1.3 lb/in spring rate across its 12-inch free length. The 0.278-inch outside diameter and 0.0348-inch wire diameter make it suited for compact mechanisms where precise load and deflection control are critical. Licensed mechanical contractors, maintenance technicians, and industrial assembly professionals typically source this type of spring for HVAC equipment linkages, control mechanisms, valve assemblies, and similar spring-loaded components.

Cut-to-length compression springs are stocked at full length and trimmed on site to meet exact application requirements. This format reduces the need to stock multiple spring lengths for similar assemblies. The M-8C20C is appropriate for light-load mechanical applications in residential and light commercial equipment, including actuator return mechanisms, damper controls, and spring-tensioned assemblies found in HVAC systems and related trade equipment. Its gray color and galvanized stainless steel construction provide corrosion resistance in moderate environments.

Compatibility

Designed as an OEM-style replacement or service stock compression spring for light mechanical assemblies requiring a 0.278-inch OD cut-to-length spring with a 1.3 lb/in spring rate.

Installation Notes

Installation is performed by licensed technicians or qualified mechanical maintenance personnel. Before servicing any spring-loaded assembly, de-energize the equipment and relieve any stored mechanical tension per the equipment manufacturer's service procedure. When trimming cut-to-length springs, use proper spring-cutting tools to ensure square, burr-free ends that seat correctly in the spring pocket. Handle cut spring ends carefully to avoid injury from sharp wire edges.
