Gardner Spring 36491GS Precision Compression Spring

Product Description

The GARDNER SPRING 36491GS is a precision compression spring manufactured from stainless steel for reliable, corrosion-resistant performance in demanding mechanical assemblies. It features a 0.48-inch outside diameter, a 0.75-inch free length, and a 0.072-inch wire diameter. With a maximum work load of 44 pounds and a spring rate of 127.75 pounds per inch, this spring is engineered for consistent deflection response across its operating range. The closed and ground end configuration provides stable seating and uniform load transfer. Maintenance technicians, mechanical assemblers, and trade professionals working with precision mechanical components will find this spring suited to tight-tolerance applications.

This precision compression spring is designed for use in compact mechanical assemblies where controlled load response and dimensional consistency are required. The 0.48-inch outside diameter fits holes up to 0.50 inches, making it compatible with standard bore and housing applications across HVAC equipment, plumbing components, valve assemblies, and general industrial mechanisms. The stainless steel construction with a plain finish performs reliably in environments exposed to moisture or mild chemical contact. It is sold in packages of 5 units.

Key Features

• Closed and ground ends for flat, stable seating and accurate load distribution
• Stainless steel construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.072-inch wire diameter provides a spring rate of 127.75 pounds per inch
• Maximum work load rated at 44 pounds (178.98 N)
• Plain silver finish with no coating to interfere with dimensional tolerances
• Solid height of 0.448 inches for predictable compressed-state clearance

Compatibility

Designed as a precision OEM-style compression spring suitable for standard mechanical assemblies requiring a 0.48-inch outside diameter spring fitting within a 0.50-inch hole diameter.

Installation Notes

Installation is performed by mechanical or trade technicians as part of valve, actuator, or equipment assembly work. De-energize and depressurize any system before replacing or installing compression springs. Use appropriate tooling to compress and seat the spring safely without overextending or cocking it within the bore. Verify the housing hole diameter and bore depth against the spring dimensions prior to installation.
