Gardner Spring 36494GS Precision Compression Spring

Product Description

The GARDNER SPRING 36494GS is a precision compression spring manufactured from stainless steel to AISI 302, ASTM A228, and ASTM A313 standards. It features a 0.48 inch outside diameter, a 1.0 inch free length, and a 0.072 inch wire diameter. The closed and ground end type provides stable seating under load, making it suitable for demanding mechanical assemblies. With a maximum work load of 44.0 pounds and a spring rate of 90.44 pounds per inch, this spring delivers consistent, repeatable force characteristics. It is installed by mechanical assemblers and maintenance technicians working on precision equipment across HVAC, plumbing, and general industrial applications.

This spring is sized to fit inside a 0.50 inch hole diameter and is well-suited for use in valve assemblies, actuators, controls, and other compression spring applications requiring tight dimensional tolerances and corrosion resistance. The plain silver finish and stainless steel construction make it appropriate for environments where moisture or chemical exposure is a concern. It is sold in a package quantity of 5 units.

Installation Notes

Install using standard mechanical assembly practices appropriate to the host equipment. Relieve all system pressure or power before servicing any valve, actuator, or control assembly containing this spring. Verify that the bore diameter, free length, and spring rate match the original equipment specification before installation. Inspect mating seats for burrs or damage that could affect seating and load distribution.
