Gardner Spring 36070G Precision Compression Spring

Product Description

The GARDNER SPRING 36070G is a precision compression spring manufactured from AISI 302 / ASTM A228 music wire with a plain silver finish. It features a 0.36-inch outside diameter, a free length of 0.812 inches, and a wire diameter of 0.0449 inches. The spring delivers a maximum working load of 16.5 pounds and a spring rate of 37 pounds per inch. Closed and ground ends provide consistent seating and accurate load transfer. This part is suited for mechanical assemblies in HVAC equipment, plumbing valve components, electrical controls, and general industrial applications where repeatable spring force is required.

This compression spring fits applications calling for a compact, high-precision spring in a 3/8-inch hole diameter clearance. It is appropriate for use in residential and light commercial mechanical systems including control valve mechanisms, actuator assemblies, and switch return mechanisms. The small form factor and tight tolerance make it a preferred choice when consistent spring rate and reliable cycling performance are critical to system operation.

Key Features

• Closed and ground end type for stable, flat seating and accurate load application
• Spring rate of 37 pounds per inch for predictable, linear deflection
• Maximum working load of 16.5 pounds (73.40 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.0449-inch wire diameter with plain silver finish - no coating to affect dimensional fit
• Solid height of 0.339 inches supports compact stack-height requirements

Compatibility

Designed as a precision OEM-style replacement or original-fit compression spring for mechanical assemblies requiring a 0.36-inch outside diameter spring seated in a 3/8-inch hole diameter.

Installation Notes

Installation is typically performed by a qualified HVAC technician, plumber, or mechanical assembler depending on the host equipment. Shut down and de-energize the system or assembly before replacing any spring component. Verify that the replacement spring seats fully and squarely against both mating surfaces before restoring operation. Confirm that the free length and spring rate match the original specification to avoid altering operating pressures or control response.
