Gardner Spring C18C Utility Compression Spring 0.313in Od

Product Description

The GARDNER SPRING C18C is a utility compression spring designed for general mechanical and industrial applications. Built from steel with a zinc plating finish, this closed-end spring delivers a spring rate of 2.76 lb/in and a maximum work load of 4.15 lb. It measures 0.313 inches outside diameter with a free length of 2 inches, making it a compact, reliable choice for assemblies where consistent force return is required. Maintenance technicians, mechanical contractors, and equipment service professionals install this type of spring in a wide range of light-load mechanisms and assemblies.

This spring is suited for residential and commercial equipment where small-format compression springs are needed. Typical applications include control linkages, valve assemblies, latch mechanisms, and light-duty return-force applications across HVAC, plumbing, electrical, and general mechanical equipment. The zinc plating provides basic corrosion resistance, making it appropriate for indoor environments and moderate-exposure service conditions. It is sold in packages of 12 units with a minimum order quantity of 1.

Key Features

• Closed end type for stable seating and consistent load transfer
• Steel construction with zinc plating for corrosion resistance
• Spring rate of 2.76 lb/in for predictable force characteristics
• Maximum work load of 4.15 lb suitable for light-duty applications
• Solid height of 0.494 inches keeps the compressed profile compact
• Wire diameter of 0.0287 inches for consistent coil geometry

Compatibility

Designed as an OEM-style replacement or service-stock compression spring for light-duty mechanical assemblies requiring a closed-end utility spring with 0.313 inches outside diameter and 2 inches free length.

Installation Notes

Compression springs of this type are installed by mechanical technicians and equipment service professionals. Always de-energize and relieve any stored mechanical, pneumatic, or hydraulic energy in the assembly before removing or installing springs. Use appropriate pliers or spring installation tools to seat the spring without over-compressing beyond the solid height. Verify the replacement spring rate and load rating match the original equipment specification before finalizing the installation.
