Gardner Spring 36587GS Precision Compression Spring

Product Description

The GARDNER SPRING 36587GS is a precision compression spring manufactured from stainless steel and designed for applications requiring consistent, repeatable force across a controlled travel range. With an outside diameter of 0.845 inches, a free length of 1 inch, and a wire diameter of 0.072 inches, this spring is built to tight tolerances suited for instrumentation, valve assemblies, mechanical controls, and industrial equipment. The closed and ground end type provides flat, stable seating surfaces that promote even load distribution and accurate spring rate performance. Rated to a maximum work load of 23 pounds with a spring rate of 30.36 pounds per inch, this unit is sized for moderate-load, short-travel duty cycles.

This spring is suited for residential and commercial mechanical assemblies where corrosion resistance and dimensional precision are required. Typical applications include HVAC equipment controls, pneumatic valve components, fluid handling assemblies, and general industrial machinery. The stainless steel construction makes it a practical choice for environments exposed to moisture, mild chemicals, or temperature cycling. It fits into a hole diameter of 0.875 inches (7/8 inch) and has a solid height of 0.334 inches, making it compatible with compact spring pocket designs where space is limited.

Key Features

• Closed and ground ends provide flat seating for accurate load transfer and alignment
• Stainless steel construction resists corrosion in wet or chemically active environments
• Spring rate of 30.36 pounds per inch supports predictable, linear force response
• Maximum work load of 23 pounds suits moderate-duty mechanical assemblies
• Solid height of 0.334 inches allows use in compact spring pocket designs
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed to fit spring pockets with a hole diameter of 0.875 inches. Suitable as an OEM-style or aftermarket replacement precision compression spring in HVAC controls, valve assemblies, and general industrial mechanical applications where closed and ground end springs of this diameter and free length are specified.

Installation Notes

Installation is typically performed by mechanical technicians or trades professionals servicing valve bodies, control assemblies, or equipment subcomponents. Always de-energize and depressurize the assembly before removing or replacing internal spring components. Verify the solid height and free length against the original specification before installing to confirm proper fit and travel. Refer to the equipment manufacturer's service documentation for any torque or preload requirements specific to the host assembly.
