Gardner Spring 36479GS Precision Compression Spring

Product Description

The GARDNER SPRING 36479GS is a precision compression spring manufactured from stainless steel for reliable performance in demanding mechanical applications. It features a 0.48-inch outside diameter and a 2.0-inch free length, with a wire diameter of 0.0551 inches and a closed and ground end type. The spring delivers a rated spring rate of 13.91 pounds per inch and a maximum work load of 20.0 pounds. These characteristics make it suitable for applications where consistent load response and corrosion resistance are required. Licensed mechanical technicians and maintenance professionals working with precision assemblies typically source this part as a direct replacement or original-fit component.

This compression spring fits applications across light industrial, HVAC, plumbing, and mechanical equipment where a compact, stainless steel compression spring is required. The 0.48-inch OD allows installation into bores up to 0.50 inches, while the 2.0-inch free length accommodates standard travel ranges in valve bodies, actuators, pressure regulators, and related assemblies. The plain silver finish and stainless steel construction make it appropriate for both dry and mildly corrosive environments.

Key Features

• Stainless steel construction resists corrosion in humid or chemically active environments
• Closed and ground ends provide flat, stable seating surfaces for accurate load application
• Spring rate of 13.91 pounds per inch supports predictable deflection under variable loads
• Maximum work load of 20.0 pounds with a solid height of 0.72 inches
• 0.50-inch recommended hole diameter allows consistent bore fit
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed as an OEM-style precision compression spring for use in mechanical assemblies requiring a 0.48-inch OD, 2.0-inch free length stainless steel spring with closed and ground ends.

Installation Notes

Installation is typically performed by licensed mechanical, HVAC, or plumbing technicians. De-energize or shut off the system and relieve any stored pressure before removing or installing compression springs in valve or actuator assemblies. Use appropriate hand tools and verify the spring seats flush against both mating surfaces before reassembly. Confirm the free length and spring rate match the original specification before replacing a spring in a safety-critical application.
