Gardner Spring 36488GS Precision Compression Spring

Product Description

The GARDNER SPRING 36488GS is a precision compression spring manufactured from stainless steel with a plain finish. It features an outside diameter of 0.48 inches, a free length of 0.5 inches, and a wire diameter of 0.072 inches. The spring carries a maximum work load of 44 pounds and a spring rate of 217.46 pounds per inch, making it suited to applications where consistent, controlled resistance over a short travel distance is required. HVAC technicians, plumbers, and mechanical assemblers commonly specify precision compression springs of this profile for valve assemblies, actuators, and equipment linkage components.

This spring is appropriate for use in compact mechanical assemblies across residential and light commercial applications. Its closed and ground end type provides flat, stable seating against mating surfaces, reducing lateral deflection during compression. The stainless steel construction resists corrosion in environments exposed to moisture, mild chemicals, or temperature cycling, which is common in HVAC, plumbing valve, and pool equipment service contexts. The 0.5-inch hole diameter accommodates standard guide rod sizing for this spring class.

Key Features

• Closed and ground ends for stable, flat seating and reduced lateral deflection
• Stainless steel construction resists corrosion in wet and chemically exposed environments
• 217.46 lb/in spring rate delivers precise, repeatable force response over short travel
• 44-pound maximum work load suits compact valve and actuator assemblies
• Solid height of 0.324 inches allows predictable deflection limits in tight housings
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed as an OEM-style precision compression spring suitable for mechanical assemblies requiring a 0.48-inch outside diameter, 0.5-inch free length, and closed and ground end configuration.

Installation Notes

Installation of compression springs should be performed by a qualified technician familiar with the host assembly. Relieve all system pressure and de-energize any associated equipment before removing or replacing springs in valve or actuator assemblies. Confirm that the guide rod or bore diameter is compatible with the spring inside diameter before installation to prevent binding or misalignment. Avoid compressing the spring beyond its solid height during assembly.
