Gardner Spring 36392G Compression Spring 0.3in Od 1in

Product Description

The GARDNER SPRING 36392G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a closed and ground end type. It delivers a spring rate of 40 pounds per inch and handles a maximum working load of 19 pounds. The outside diameter measures 0.3 inches, free length is 1 inch, and wire diameter is 0.045 inches. These tight-tolerance springs are used by mechanical technicians, toolmakers, and OEM assembly operations wherever repeatable force and compact form factor are required.

This compression spring fits a wide range of light-duty mechanical, industrial, and OEM applications. Its compact 0.3 inch OD and 1 inch free length make it suitable for use in valves, switches, tool assemblies, fixtures, and precision instruments. The plain silver finish and music wire construction suit dry or lightly lubricated environments. Sold in packages of 5, these springs are appropriate for both service replacement and bench-stock replenishment in maintenance, repair, and assembly operations.

Compatibility

Designed as an OEM-style precision compression spring suitable for mechanical assemblies, valve mechanisms, and light-duty industrial applications requiring a 0.3 inch OD closed-and-ground spring with a 1 inch free length.

Installation Notes

Installation is typically performed by mechanical technicians or OEM assembly personnel. Ensure the mating bore or housing does not exceed the rated hole diameter of 0.313 inches to maintain proper spring alignment. De-energize or depressurize any system before replacing compression springs in live assemblies. Avoid compressing the spring past its solid height of 0.518 inches during installation to prevent set or permanent deformation.
