Gardner Spring 36440GS Compression Spring Stainless Steel

Product Description

The GARDNER SPRING 36440GS is a precision compression spring manufactured from stainless steel with a plain finish. It measures 0.42 inches in outside diameter and 1 inch in free length, with a wire diameter of 0.0421 inches. The spring delivers a rated spring rate of 13.91 pounds per inch and supports a maximum work load of 10 pounds. With closed and ground ends, it is suited for applications requiring consistent deflection, controlled load, and stable seating. This type of precision spring is installed by mechanical assemblers, maintenance technicians, and trade professionals across HVAC, plumbing, and industrial equipment applications.

The 36440GS fits applications where a compact, corrosion-resistant compression spring is required. The stainless steel construction makes it appropriate for environments with exposure to moisture, mild chemicals, or temperature variation. Typical use cases include valve assemblies, actuator mechanisms, pressure relief components, and equipment used in HVAC, plumbing, and pool or water treatment systems. The 0.4380-inch hole diameter fit and 0.316-inch solid height make it compatible with tight-clearance assemblies requiring a low-profile spring at full compression.

Key Features

• Stainless steel construction with plain finish for corrosion resistance in wet or humid environments
• Closed and ground ends for flat, stable seating and accurate load transfer
• Spring rate of 13.91 pounds per inch for predictable, linear deflection
• Maximum work load of 10 pounds suitable for light-duty precision applications
• Solid height of 0.316 inches allows use in compressed assemblies with tight travel limits
• Precision spring type for consistent performance across repeated cycles

Compatibility

Designed as an OEM-style precision compression spring for use in mechanical assemblies requiring a 0.42-inch outside diameter, 1-inch free length spring with closed and ground ends.

Installation Notes

Installation is typically performed by a qualified mechanical technician or trade professional. Ensure the mating bore or rod diameter is within tolerance before installation, referencing the 0.4380-inch hole diameter and 0.42-inch outside diameter specifications from the input. De-energize or depressurize any associated system before disassembling the spring cavity. Avoid over-compressing the spring beyond its solid height of 0.316 inches, as this can cause permanent set and loss of rated load capacity.
