Gardner Spring 36530G Precision Compression Spring

Product Description

The GARDNER SPRING 36530G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It measures 0.6 inches in outside diameter and 1.5 inches in free length, with a wire diameter of 0.072 inches and a solid height of 0.686 inches. The spring delivers a rate of 36 pounds per inch and handles a maximum work load of 29 pounds (160.14 N). Closed and ground ends provide flat, stable seating against mating surfaces. Maintenance technicians, machine builders, and trade professionals across HVAC, plumbing, and industrial applications use this spring in precision assemblies where consistent force and deflection characteristics are required.

This compression spring is suited for light-duty precision applications including valve assemblies, actuator mechanisms, and equipment controls in residential and commercial systems. Its compact dimensions make it a fit for tight-clearance installations where a reliable, repeatable spring force is needed. The recommended hole diameter for installation is 0.625 inches (5/8 inches). Sold in packages of 5, it is appropriate for service stock or low-volume assembly work.

Key Features

• Closed and ground ends for flat, stable seating and accurate load measurement
• 36 pounds per inch spring rate for predictable, linear deflection
• 29 pound maximum work load (160.14 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.072 inch wire diameter with plain silver finish
• Compact 0.686 inch solid height suits tight-clearance assemblies

Compatibility

Designed as a precision OEM-style compression spring for use in valve assemblies, actuator mechanisms, and equipment controls where a 0.6 inch outside diameter and 1.5 inch free length spring is specified. Fits into a 0.625 inch hole diameter as noted in manufacturer specifications.

Installation Notes

Installation is performed by qualified technicians familiar with spring-loaded mechanical assemblies. Always de-energize and depressurize the system before disassembling any spring-loaded valve, actuator, or control component. Verify the new spring rate and free length match the original specification before installation. Do not compress the spring beyond its solid height, as doing so can permanently deform the coils and compromise load performance.
