Gardner Spring 36308G Precision Compression Spring

Product Description

The GARDNER SPRING 36308G is a precision compression spring manufactured from AISI music wire to close-and-ground end specifications. It carries an outside diameter of 0.24 inches, a free length of 1 inch, and a wire diameter of 0.026 inches. The spring delivers a rated spring rate of 7.4 pounds per inch and handles a maximum work load of 5 pounds. Solid height is 0.30 inches. This type of spring is specified by mechanical engineers and installed by maintenance technicians, millwrights, and HVAC or fluid-system assemblers working on small-diameter spring seats or valves.

The 36308G fits applications requiring a compact, light-duty compression spring in a hole diameter of 0.25 inches or less. Typical uses include valve assemblies, flow-control mechanisms, latching hardware, and light-load return applications in residential and light commercial equipment. The plain silver finish and music wire construction suit dry or low-moisture indoor environments. This part is sold in packages of five, making it appropriate for both single-repair jobs and low-volume production runs.

Key Features

• Spring rate of 7.4 pounds per inch for predictable, linear load response
• Maximum work load of 5 pounds with a solid height of 0.30 inches
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.24 inches OD fits a 0.25-inch hole diameter clearance
• Plain finish; suitable for dry indoor service environments

Compatibility

Designed as an OEM-style or replacement precision compression spring for applications requiring a 0.24-inch outside diameter, 1-inch free length, and 0.026-inch wire diameter in a closed-and-ground configuration.

Installation Notes

Installation is performed by qualified mechanical technicians or assemblers. De-energize and depressurize any system before replacing or inserting compression springs in valve bodies or actuator assemblies. Confirm the spring pocket or bore matches the 0.25-inch hole diameter specification before seating the spring. Do not stretch or pre-load the spring beyond its rated maximum work load of 5 pounds, as permanent set or premature fatigue may result.
