Gardner Spring C31C Utility Compression Spring 0.375in Od

Product Description

The GARDNER SPRING C31C is a closed-end utility compression spring manufactured for general-purpose mechanical and industrial applications. It measures 0.375 inches in outside diameter with a free length of 2 inches and a wire diameter of 0.0346 inches. The spring delivers a rate of 4.2 pounds per inch and supports a maximum working load of 6.24 pounds. With a solid height of 0.515 inches and a zinc finish over steel construction, it provides consistent load performance in compact assemblies. Licensed trades and maintenance technicians commonly stock this spring for HVAC, plumbing, and mechanical service work.

The C31C fits residential and light commercial mechanical assemblies where a compact compression spring with defined load and rate characteristics is required. Typical applications include valve assemblies, damper linkages, equipment latches, and panel retention hardware. Its closed ends provide stable seating against flat surfaces, making it suitable for guided spring seats in tight clearance housings. Sold in packages of 12, it is well suited for bench stock in service shops and field service kits.

Key Features

• Sold in quantities of 12 for efficient bench stock management

Compatibility

Designed as a general-purpose utility compression spring suitable for a wide range of mechanical assemblies requiring a 0.375 inch OD, 2 inch free length, closed-end spring with a 4.2 pound per inch rate.

Installation Notes

Installation is performed by maintenance technicians and licensed trades during equipment service or assembly. Depressurize or de-energize the host assembly before removing or installing springs to prevent uncontrolled release of stored energy. Verify that the spring pocket or guide diameter provides adequate clearance around the 0.375 inch OD without allowing lateral buckling under full deflection. Do not compress the spring beyond its solid height of 0.515 inches during installation or operation.
