Gardner Spring C43C Utility Compression Spring 0.438in Od

Product Description

The GARDNER SPRING C43C is a utility compression spring designed for general-purpose mechanical applications requiring consistent, controlled resistance across a defined load range. Built with a 0.438-inch outside diameter and a free length of 2.5 inches, this spring delivers a spring rate of 8.66 pounds per inch and supports a maximum work load of 14.94 pounds. The closed end type provides stable seating on flat surfaces, making it suitable for use in fixtures, assemblies, valves, and mechanical controls. It is installed by maintenance technicians and mechanical contractors across light industrial and commercial settings.

This spring fits general utility applications where a compact compression spring with predictable load deflection is required. Typical use cases include equipment assemblies, tool fixtures, valves, latches, and spring-loaded mechanical mechanisms. The 0.438-inch OD and 2.5-inch free length make it a practical fit for standard hardware configurations in light industrial, HVAC, plumbing, and general mechanical service environments. Available in a package quantity of 12, it suits bench stock and service kit applications equally well.

Installation Notes

Compression springs of this type are installed by mechanical technicians and general maintenance professionals. Ensure the mating bore or spring pocket diameter is appropriately sized relative to the 0.438-inch OD to prevent binding or misalignment under load. De-energize or depressurize any assembly before replacing a spring under load. Refer to equipment manufacturer documentation for seat depth and preload requirements specific to the host assembly.
