Gardner Spring 36398G Precision Compression Spring

Product Description

The GARDNER SPRING 36398G is a precision compression spring manufactured from AISI 302-compliant music wire. It measures 0.36 inches in outside diameter with a free length of 1 inch and a wire diameter of 0.026 inches. The spring delivers a rated spring rate of 4 pounds per inch and a maximum work load of 3 pounds. Closed and ground ends provide flat, stable seating against mating surfaces. The plain silver finish leaves the music wire in its natural state, making it suitable for applications where corrosion exposure is limited. Maintenance technicians, OEM assemblers, and mechanical service professionals use this spring as a direct replacement or new-installation component in light-load mechanical assemblies.

This compression spring is sized for use in small mechanical devices, valve assemblies, instrument housings, and light-duty industrial or HVAC control mechanisms where a compact, low-load spring element is required. The 3/8-inch hole diameter fit and 0.17-inch solid height make it well suited for confined spring pockets with limited travel. It is packaged in quantities of 5, making it practical for bench stock or small-volume repair jobs.

Key Features

• Closed and ground ends for flat, consistent seating on both contact surfaces
• 4 pounds per inch spring rate for predictable, linear deflection under load
• 3-pound maximum work load keeps the spring within its elastic range during normal service
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.17-inch solid height suits shallow spring pockets with minimal clearance
• Plain silver finish; no coating to flake or contaminate the assembly

Compatibility

Designed as an OEM-style precision compression spring for light-load mechanical assemblies requiring a 0.36-inch outside diameter and 1-inch free length with closed and ground ends.

Installation Notes

Installation of compression springs in mechanical assemblies is typically performed by maintenance technicians or assemblers. Always relieve system pressure and de-energize any actuators or valve mechanisms before removing or installing springs. Verify the spring pocket diameter and solid height clearance match the application before compressing the spring to working load. Do not compress the spring beyond its solid height, as this will permanently set the coils and alter the rated spring rate.
