Gardner Spring 36046G Precision Compression Spring

Product Description

The GARDNER SPRING 36046G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It features a 0.300-inch outside diameter, a free length of 0.687 inches, and a wire diameter of 0.032 inches. The spring delivers a maximum work load of 7.5 pounds and a spring rate of 16 pounds per inch. The ends are closed and ground for consistent seating and load transfer. This part is suited for use in mechanical assemblies, HVAC equipment, valves, and other precision applications where compact spring force is required. Technicians and assemblers working with light-load compression applications will find this spring dimensionally consistent and standards-compliant.

This compression spring fits applications requiring a small-diameter, short-length spring element. It is commonly used in residential and light commercial HVAC systems, fluid control valves, pneumatic devices, and general mechanical assemblies. The closed and ground end configuration allows the spring to seat flat against mating surfaces, making it appropriate for precision sub-assemblies where load alignment matters. Each package contains 5 springs with a minimum order quantity of 1.

Key Features

• Closed and ground ends for stable, flat seating and accurate load transfer
• Spring rate of 16 pounds per inch for predictable deflection behavior
• Maximum work load of 7.5 pounds (33.36 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.300-inch OD fits a 0.312-inch hole diameter for guided installation
• Plain silver finish with no coating - ready for direct installation

Compatibility

Designed as an OEM-style precision compression spring for mechanical and HVAC sub-assemblies requiring a 0.300-inch OD, 0.687-inch free-length spring element with closed and ground ends.

Installation Notes

Installation is typically performed by mechanical technicians or HVAC service professionals during component-level assembly or valve servicing. Power down or de-energize any system before replacing internal spring components. Ensure the mating bore diameter is consistent with the 0.312-inch hole diameter spec to maintain proper spring guidance and prevent buckling under load. Do not compress the spring beyond its solid height of 0.241 inches during installation.
