Gardner Spring 36068G Precision Compression Spring

Product Description

The GARDNER SPRING 36068G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It measures 0.36 inches in outside diameter and 1.5 inches in free length, with a wire diameter of 0.042 inches. The spring delivers a spring rate of 14.5 pounds per inch and handles a maximum work load of 13.5 pounds (60.05 N). Closed and ground ends provide flat, stable seating surfaces for consistent load transfer. This part is suited for licensed mechanical tradespeople and precision assembly technicians working with mechanical systems that require repeatable spring force in tight spaces.

The 36068G fits applications where a compact, small-diameter compression spring is required. Its 0.36 inch OD allows installation into a bore or hole with a recommended diameter of 0.375 inches (3/8 inch), making it appropriate for valve assemblies, light mechanical controls, HVAC damper actuators, pump mechanisms, and other equipment found in commercial and residential installations. The solid height of 0.527 inches defines the maximum compressed limit for design clearance calculations.

Key Features

• Closed and ground ends for flat seating and consistent load distribution
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 14.5 pounds per inch for predictable deflection behavior
• Maximum work load of 13.5 pounds (60.05 N)
• Outside diameter of 0.36 inches fits into a 0.375 inch (3/8 inch) bore
• Plain silver finish with no coating that could alter dimensional tolerances

Compatibility

Designed as a precision replacement or original-fit compression spring for mechanical assemblies requiring a 0.36 inch OD, 1.5 inch free length spring with a 14.5 pounds per inch spring rate and closed ground ends.

Installation Notes

Installation is performed by mechanical and assembly technicians. Depressurize, de-energize, or otherwise isolate the assembly before replacing any spring component. Verify that the mating bore diameter is 0.375 inches to ensure proper fit and prevent side loading. Do not compress the spring beyond its solid height of 0.527 inches during installation or operation.
