Gardner Spring 36479G Precision Compression Spring

Product Description

The GARDNER SPRING 36479G is a precision compression spring manufactured from music wire with a plain finish. It features a 0.48 inch outside diameter, a free length of 2 inches, and a wire diameter of 0.0551 inches. The spring delivers a rate of 16 pounds per inch and supports a maximum work load of 20 pounds (88.97 N). Ends are closed and ground for stable seating and accurate load transfer. This type of spring is used across HVAC equipment, plumbing assemblies, and light industrial mechanisms wherever consistent compression force and dimensional repeatability are required.

This compression spring fits applications requiring a 0.48 inch OD component in a hole diameter up to 0.5 inches. The 2 inch free length compresses to a solid height of 0.72 inches, making it suitable for installations with limited travel space. It is commonly specified in valve assemblies, damper mechanisms, actuator returns, and pressure-relief devices found in residential and light commercial trade equipment. Available in minimum order quantities of 1, packaged in quantities of 5.

Key Features

• Closed and ground ends provide flat, stable bearing surfaces for accurate load application
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 16 pounds per inch spring rate for consistent, predictable deflection
• 20 pound maximum work load with solid height of 0.72 inches
• Plain silver finish - no coating to interfere with dimensional tolerances
• Precision classification ensures tight dimensional and load tolerances

Compatibility

Designed as an OEM-style replacement or direct-fit precision compression spring for assemblies requiring a 0.48 inch OD, 0.5 inch hole diameter clearance, and 2 inch free length in music wire construction.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial maintenance personnel. De-energize and depressurize the system before removing or replacing any spring component. Use appropriately rated hand tools and verify the replacement spring rate and load specifications match the original equipment requirements before installation. Confirm end seating surfaces are clean and flat to ensure accurate load transfer.
