Gardner Spring 36039G Precision Compression Spring

Product Description

The GARDNER SPRING 36039G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It measures 0.3 inches in outside diameter with a free length of 0.5 inches and a wire diameter of 0.022 inches. The spring delivers a maximum work load of 2.5 pounds and a spring rate of 6.5 pounds per inch. With closed and ground ends, it seats squarely and consistently under load. This spring is suited for use in mechanical assemblies, instruments, valves, and light-duty industrial or HVAC applications where a compact, repeatable compression element is required.

The 36039G fits applications calling for a small-diameter compression spring with precise dimensional tolerances. Its compact form factor makes it appropriate for use in residential and commercial mechanical systems, valve assemblies, actuators, and control mechanisms where space is limited and consistent spring force is critical. Installers in HVAC, plumbing, and general mechanical service will encounter this spring type in a range of equipment service scenarios.

Key Features

• Closed and ground ends for stable, flat seating under compression
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 6.5 pounds per inch for consistent, predictable deflection
• Maximum work load of 2.5 pounds within a 0.5-inch free length
• Solid height of 0.106 inches allows for compact installation clearances
• Plain silver finish - no coating to interfere with dimensional fit

Compatibility

Designed as an OEM-style precision compression spring replacement for mechanical assemblies requiring a 0.3-inch outside diameter, 0.5-inch free length compression spring with closed and ground ends. Hole diameter clearance is 0.312 inches.

Installation Notes

Installation is typically performed by a qualified mechanic or technician during equipment assembly or service. De-energize and isolate any equipment before disassembling spring-loaded components. Verify that the mating bore or guide post matches the specified hole diameter of 0.312 inches and that adequate clearance exists at solid height before reassembly. Do not compress the spring beyond its solid height during installation.
