Gardner Spring 36221GS Compression Spring 0.12in Od Stainless

Product Description

The GARDNER SPRING 36221GS is a precision compression spring manufactured from stainless steel for reliable, corrosion-resistant performance in demanding service environments. It features a 0.12-inch outside diameter and a 1.5-inch free length, with a wire diameter of 0.0161 inches. The spring delivers a maximum work load of 5 pounds and a spring rate of 8.43 lb per inch, making it well-suited for light-duty compression applications where consistent force and dimensional accuracy are critical. Closed and ground ends provide stable seating and predictable load behavior across the usable travel range. Licensed trades and maintenance professionals working on HVAC controls, plumbing valves, electrical assemblies, and mechanical actuators commonly specify this spring type.

This compression spring is designed for use in residential and light commercial mechanical assemblies where a small-diameter, corrosion-resistant spring is required. Its stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or temperature cycling. The 0.125-inch hole diameter spec indicates suitability for shaft-guided installations. Applications include valve return mechanisms, actuator return assemblies, switch plungers, and similar components found in HVAC, plumbing, and electrical control systems.

Key Features

• 0.12-inch outside diameter with closed and ground ends for stable, square seating
• 1.5-inch free length with a 0.902-inch solid height
• Wire diameter of 0.0161 inches for precise load characteristics
• Maximum work load of 5 pounds (23.19 N) at rated travel
• Spring rate of 8.43 lb per inch for predictable, linear force delivery
• Stainless steel construction with plain finish meets AISI 302, ASTM A228, and ASTM A313 standards

Compatibility

Designed as an OEM-style replacement or sourcing solution for precision compression spring applications requiring a 0.12-inch OD, 1.5-inch free length, closed and ground end configuration in stainless steel.

Installation Notes

Install by qualified mechanical, HVAC, or plumbing technicians as appropriate to the host assembly. Confirm shaft or bore dimensions against the 0.125-inch hole diameter and 0.12-inch OD specifications before installation to ensure proper fit and concentricity. De-energize or depressurize any system before disassembly when replacing springs in valve, actuator, or control assemblies. Avoid overcompressing below the 0.902-inch solid height to prevent set or permanent deformation.
