Gardner Spring C42C Utility Compression Spring 0.375 in Od

Product Description

The GARDNER SPRING C42C is a utility compression spring suited for general mechanical and industrial applications. It features a 0.375 inch outside diameter and a 3 inch free length, with a wire diameter of 0.0476 inches. The spring rate is 10.82 pounds per inch, and the maximum work load is 21.52 pounds. Constructed from steel with a zinc finish, this spring delivers consistent return force across a range of light-duty compression applications. Licensed tradespeople and maintenance technicians working on HVAC equipment, plumbing assemblies, electrical enclosures, and general mechanical systems will find this a reliable hardware component.

This compression spring is designed for utility-grade use in residential and commercial mechanical systems. Typical applications include valve return mechanisms, damper assemblies, panel latches, and other spring-loaded components requiring a closed-end compression spring with a 3/8 inch OD. The closed end type allows for stable seating on flat surfaces, making it straightforward to install in tight or confined mounting points.

Key Features

• 0.375 inch outside diameter for standard 3/8 inch utility spring fitment
• 3 inch free length with a solid height of 1.012 inches
• Spring rate of 10.82 pounds per inch for predictable compression response
• Maximum work load of 21.52 pounds
• Closed end type for stable, flat-seated installation
• Zinc finish over steel construction for general-duty corrosion resistance

Compatibility

Designed as a utility-grade replacement compression spring for mechanical assemblies requiring a closed-end spring with a 0.375 inch outside diameter and 3 inch free length.

Installation Notes

This spring is installed by maintenance technicians and mechanical tradespeople across HVAC, plumbing, and electrical panel applications. Relieve system pressure and de-energize any associated equipment before removing or replacing compression springs in loaded assemblies. Verify that the spring seat diameter and bore clearance match the 0.375 inch OD before installation to prevent misalignment under load.
