Gardner Spring 36407GS Precision Compression Spring

Product Description

The GARDNER SPRING 36407GS is a precision compression spring manufactured from stainless steel to AISI 302 and ASTM A313 standards. It has an outside diameter of 0.36 inches, a free length of 0.75 inches, and a wire diameter of 0.0319 inches. The spring delivers a maximum work load of 6 pounds and a spring rate of 10.43 pounds per inch. Closed and ground ends provide flat, stable seating surfaces for accurate load transfer. This spring is suited for use in mechanical assemblies, valve components, fluid controls, and precision equipment across HVAC, plumbing, and related trade applications where consistent force and corrosion resistance are required.

The 36407GS is a compact, lightweight precision spring appropriate for residential and commercial mechanical systems. Its stainless steel construction and plain finish make it a reliable choice in environments subject to moisture, chemicals, or elevated temperatures. Typical installation scenarios include valve actuators, pressure-relief mechanisms, and small mechanical linkage assemblies. The spring fits into a hole diameter of 0.375 inches, making it straightforward to locate and retain during assembly.

Key Features

• Stainless steel construction meets AISI 302, ASTM A228, and ASTM A313 standards for corrosion resistance and consistent mechanical properties
• Closed and ground end type provides flat bearing surfaces for stable load distribution
• Maximum work load of 6 pounds with a spring rate of 10.43 pounds per inch for predictable deflection behavior
• Outside diameter of 0.36 inches fits a 0.375 inch hole for secure, centered seating
• Solid height of 0.185 inches limits over-compression and protects the spring in tight-clearance assemblies
• Plain silver finish with no coating to interfere with fit or conductivity in precision applications

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.36 inch outside diameter, 0.75 inch free length, and stainless steel construction across HVAC, plumbing, and industrial equipment applications.

Installation Notes

Installation is typically performed by a licensed mechanic, HVAC technician, or plumber depending on the host assembly. De-energize or depressurize the system before replacing any spring component. Verify the solid height and free length against the application requirements before installation to avoid over-compression or insufficient preload. Use appropriate hand tools and follow all applicable equipment manufacturer guidelines and local codes during service.
