Gardner Spring 36116G Precision Compression Spring

Product Description

The GARDNER SPRING 36116G is a precision compression spring manufactured from music wire with a plain finish. It is designed for applications requiring consistent, repeatable force across a defined compression stroke. The spring features a 0.72 inch outside diameter, a 2 inch free length, and a 0.055 inch wire diameter. With a spring rate of 8.5 pounds per inch and a maximum work load of 13 pounds, it suits assemblies where controlled resistance and compact geometry are critical. Closed and ground ends provide flat, stable seating surfaces for accurate load transfer. HVAC technicians, plumbers, and mechanical assemblers encounter this spring type in valve assemblies, actuator mechanisms, and equipment linkage components.

This precision spring is suited for use in both residential and commercial mechanical assemblies where a small-diameter, light-duty compression spring is required. The 0.72 inch OD is sized to fit a 0.75 inch hole diameter, allowing direct installation into bored housings or counterbores without additional hardware. Its silver, plain finish and music wire construction make it appropriate for dry or lightly lubricated environments. Typical install scenarios include control linkages, valve return mechanisms, and spring-loaded couplings found across HVAC, plumbing, and general mechanical equipment.

Key Features

• 8.5 lb/in spring rate for predictable, linear force response
• 13 pound maximum work load with a solid height of 0.421 inches
• Closed and ground ends for flat, stable bearing surfaces
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Plain silver finish suitable for dry or lightly lubricated service environments

Compatibility

Designed as an OEM-style precision compression spring for residential and commercial mechanical assemblies requiring a 0.72 inch OD, 2 inch free length spring with closed and ground ends.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or mechanical service professionals during valve or actuator servicing. Relieve all system pressure and de-energize any associated electrical circuits before disassembling spring-loaded components. Verify that the mating bore diameter and seating surfaces are clean and free of burrs before installing the spring. Inspect the replacement spring against the original for matching OD, free length, and end type before finalizing assembly.
