Gardner Spring 36404GS Precision Compression Spring

Product Description

The GARDNER SPRING 36404GS is a precision compression spring manufactured from stainless steel with a plain finish. It features a 0.36-inch outside diameter and a 2-inch free length, making it suitable for compact mechanical assemblies where consistent load response is required. The spring delivers a maximum work load of 3 pounds and a spring rate of 1.83 pounds per inch. Closed and ground ends provide flat, stable seating against mating surfaces, reducing lateral movement under load. Licensed technicians and mechanical assemblers working on HVAC equipment, plumbing valve assemblies, and related trade hardware use springs of this type in tension-controlled mechanisms and actuator return systems.

This compression spring fits into a hole diameter of 0.375 inches and is sized for applications where precise load control and dimensional consistency are critical. It is well suited for residential and light commercial mechanical assemblies, valve actuators, pressure-relief mechanisms, and similar hardware found across HVAC, plumbing, and pool equipment. The stainless steel construction and AISI 302 compliance make it appropriate for environments where mild corrosion resistance is needed. The package quantity is 5 pieces per order with a minimum order quantity of 1.

Compatibility

Designed as a precision OEM-style replacement compression spring for mechanical assemblies requiring a 0.36-inch OD, 2-inch free length, and 0.026-inch wire diameter in stainless steel.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified mechanical assemblers. De-energize and depressurize any system before replacing internal spring components. Verify that the mating bore diameter, free length, and load rating of the replacement spring match the original specification before assembly. Do not modify or compress the spring beyond its solid height during installation.
