Gardner Spring 36089G Precision Compression Spring

Product Description

The GARDNER SPRING 36089G is a precision compression spring manufactured from AISI 302 music wire to meet ASTM A228 and ASTM A313 standards. It features a 0.48-inch outside diameter, a 1.5-inch free length, and a 0.042-inch wire diameter. The spring delivers a maximum work load of 9.5 pounds and a spring rate of 8.5 pounds per inch. Closed and ground ends provide stable seating and consistent load transfer. With a solid height of 0.379 inches and a plain silver finish, this spring suits precision mechanical assemblies where dimensional accuracy and repeatable force output are required.

This compression spring is used in a wide range of industrial and mechanical applications where compact, consistent spring force is needed. It fits into holes up to 0.50 inches in diameter, making it well suited for valve assemblies, actuators, tooling fixtures, and general mechanical components in both light industrial and trade equipment settings. Licensed technicians and mechanical assemblers working on HVAC equipment, fluid control valves, and similar hardware will find this spring appropriate for OEM-style replacements or new assembly work.

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.48-inch OD, 1.5-inch free length spring with closed and ground ends.

Installation Notes

Install this spring with all associated mechanical assemblies fully depressurized or de-energized before handling. Verify hole and rod clearances against the 0.50-inch hole diameter and 0.48-inch OD specifications before installation. Use appropriate assembly tools to avoid overcompressing beyond the solid height of 0.379 inches, which can permanently set the spring. Replacement should be performed by a qualified technician familiar with the equipment being serviced.
