Gardner Spring C33C Utility Compression Spring 0.375in Od

Product Description

The GARDNER SPRING C33C is a utility compression spring designed for general-purpose mechanical applications requiring controlled axial force. It features an outside diameter of 0.375 inches, a free length of 2.5 inches, and a wire diameter of 0.0346 inches. The spring delivers a rate of 3.4 pounds per inch and a maximum work load of 6.4 pounds. Closed ends provide stable seating and consistent load transfer. With a solid height of 0.619 inches and a silver zinc finish, this spring is suited to environments where light corrosion resistance and dimensional consistency are required. Machinists, maintenance technicians, and mechanical assembly professionals install this type of spring across a broad range of equipment.

This compression spring is used in light-duty mechanical assemblies, tooling fixtures, latching mechanisms, valves, and general industrial equipment. Its compact form factor and predictable spring rate make it a reliable choice for OEM assemblies and MRO replacement applications alike. The closed end style supports flat seating against mating components without additional hardware. Sold in packages of 12, it is suited for shops and technicians who maintain inventory of standard compression springs for ongoing service work.

Compatibility

Designed as a standard utility compression spring for general mechanical assemblies. Suitable as a direct replacement in any application requiring a closed-end compression spring with 0.375 inches outside diameter, 2.5 inches free length, and a 3.4 pounds per inch spring rate.

Installation Notes

Compression springs of this type are installed by maintenance technicians and mechanical assemblers. Before replacing a spring in any assembly, relieve all stored mechanical energy and de-energize the equipment per applicable lockout/tagout procedures. Verify seating surfaces are clean and free of burrs to prevent coil damage and ensure consistent load behavior. Do not compress the spring beyond its solid height during installation or operation.
