Gardner Spring 36039GS Precision Compression Spring

Product Description

The GARDNER SPRING 36039GS is a precision compression spring manufactured from stainless steel for consistent, repeatable performance in demanding mechanical assemblies. The spring measures 0.3 inches in outside diameter with a 0.5 inch free length and a wire diameter of 0.022 inches. It delivers a maximum work load of 2.17 pounds and a spring rate of 5.65 pounds per inch, making it well suited for applications that require a small, precise force element in a compact envelope. Licensed technicians and mechanical assemblers install this spring in equipment where tight dimensional tolerances and corrosion resistance are both required.

This spring is used in light-duty mechanical, HVAC, plumbing, and industrial control applications where a small-format compression spring is needed to maintain pressure, return a valve component, or hold a mechanism in position. Its plain finish and silver color are appropriate for visible or semi-exposed assemblies. The closed and ground end type provides flat, stable seating against mating surfaces, which is important in precision instrument and control valve installations.

Key Features

• Closed and ground ends for flat, stable seating and accurate load transfer
• Stainless steel construction meeting AISI 302, ASTM A228, and ASTM A313 standards for corrosion resistance
• Spring rate of 5.65 pounds per inch for predictable, linear deflection
• Maximum work load of 2.17 pounds supports light-duty precision force applications
• Compact 0.3 inch OD fits hole diameters up to 0.312 inches
• Solid height of 0.106 inches minimizes stack length at full compression

Compatibility

Designed as a precision replacement or OEM-style compression spring for mechanical assemblies requiring a 0.3 inch outside diameter, 0.5 inch free length, closed and ground end spring in stainless steel.

Installation Notes

Installation is performed by licensed technicians or qualified assemblers working on mechanical or electromechanical equipment. Relieve all pressure and de-energize the system before removing or replacing any spring component. Use proper spring handling tools to avoid over-compression beyond the solid height of 0.106 inches, which can cause permanent set and loss of rated spring rate. Verify that the mating bore does not exceed 0.312 inches to ensure proper spring alignment and seating.
