Gardner Spring 36215G Precision Compression Spring

Product Description

The GARDNER SPRING 36215G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It measures 0.12 inches outside diameter with a 1 inch free length and a wire diameter of 0.022 inches. The spring delivers a rate of 15 pounds per inch and supports a maximum working load of 6 pounds. Closed and ground ends provide flat, stable seating under load. This spring fits into holes sized at 0.125 inches diameter. Technicians, assemblers, and maintenance professionals working with precision mechanisms specify this part for consistent, repeatable force characteristics.

The 36215G is suited for light-duty precision applications requiring controlled compression force in a compact envelope. Typical uses include instrument assemblies, valve mechanisms, and small electromechanical devices found in HVAC controls, plumbing valves, and industrial equipment. The closed and ground end configuration ensures uniform load distribution and reduces side loading, making it appropriate for guided spring installations where concentricity matters. The plain silver finish is appropriate for dry and lightly protected environments.

Key Features

• Closed and ground ends for flat seating and consistent load application
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 15 pounds per inch for predictable deflection under load
• Maximum working load of 6 pounds with a solid height of 0.6 inches
• Outside diameter of 0.12 inches fits holes sized at 0.125 inches
• Plain silver finish suitable for dry and lightly protected installations

Compatibility

Designed as a precision replacement or OEM-style compression spring for assemblies requiring a 0.12 inch OD, 1 inch free length, 0.022 inch wire diameter spring with closed and ground ends in music wire.

Installation Notes

Installation is typically performed by qualified technicians during assembly or maintenance of mechanical and electromechanical components. De-energize or depressurize the system before replacing any spring component. Verify that the mating bore or guide pin dimensions match the hole diameter and wire size specifications before seating the spring. Do not exceed the rated maximum working load, as compressing beyond the solid height can cause permanent set and premature failure.
