Gardner Spring 36407G Precision Compression Spring

Product Description

The GARDNER SPRING 36407G is a precision compression spring manufactured from music wire (AISI 302, ASTM A228, ASTM A313). It features a 0.36 inch outside diameter, a 0.75 inch free length, and a 0.032 inch wire diameter. The spring delivers a maximum work load of 6 pounds and a spring rate of 12 pounds per inch. Closed and ground ends provide consistent seating and uniform load distribution. The plain silver finish is standard for music wire compression springs of this class. This part is sized for applications requiring a tight, precise fit in small mechanical assemblies across industrial, HVAC, and equipment service applications.

This compression spring fits installations where a 3/8 inch hole diameter clearance and a 0.185 inch solid height are required. It is suited for use in light-duty mechanical assemblies, valve bodies, actuator mechanisms, and similar components where controlled compression and repeatable load characteristics are needed. The 12 lb/in spring rate makes it appropriate for low-force, precision-tolerance applications. Sold in packages of 5 with a minimum order quantity of 1 package.

Key Features

• 0.36 inch outside diameter with closed and ground ends for stable, flat seating
• 12 lb/in spring rate provides consistent, predictable compression behavior
• 6 pound maximum work load rated per AISI 302, ASTM A228, and ASTM A313 standards
• Music wire construction for high tensile strength and fatigue resistance
• 0.185 inch solid height and 3/8 inch recommended hole diameter for precise fitment

Compatibility

Designed as a precision replacement or service compression spring for mechanical assemblies requiring a 0.36 inch OD, 0.75 inch free length, and 12 lb/in spring rate with closed and ground ends.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical service professionals working on valve assemblies, actuators, or similar components. De-energize and relieve all system pressure before disassembling any spring-loaded component. Verify that the mating bore or hole diameter accommodates the 3/8 inch recommended clearance and that the assembly can accept the 0.185 inch solid height at full compression. Do not exceed the rated 6 pound maximum work load during installation or operation.
