Gardner Spring 36013G Precision Compression Spring

Product Description

The GARDNER SPRING 36013G is a precision compression spring manufactured from music wire with a plain silver finish. It measures 0.18 inches in outside diameter and 0.5 inches in free length, with a wire diameter of 0.0181 inches and a solid height of 0.132 inches. The spring delivers a rated spring rate of 7 pounds per inch and supports a maximum work load of 2.38 pounds (10.56 N). Closed and ground ends provide stable seating and consistent load transfer. This type of small-format compression spring is installed by mechanical technicians and equipment assemblers across HVAC, plumbing, and light industrial applications where precise force control in a compact form factor is required.

The 36013G is suited for use in residential and light commercial equipment where a small-diameter, short-length compression spring is needed to maintain pressure, return a mechanism, or provide consistent resistance. Its music wire construction and conformance to established material standards make it appropriate for dynamic cycling applications. The hole diameter of 0.187 inches accommodates standard post or pin mounting inside assemblies. Typical install scenarios include valve assemblies, actuator mechanisms, and equipment control linkages.

Key Features

• 0.18 inch outside diameter fits compact assemblies with limited radial clearance
• 7 pounds per inch spring rate provides consistent, predictable load response
• Closed and ground ends ensure flat, stable seating against mating surfaces
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Plain silver finish suitable for dry or lightly lubricated environments
• 0.187 inch hole diameter for post or pin mounting compatibility

Compatibility

Designed as an OEM-style precision compression spring for use in mechanical assemblies requiring a 0.18 inch OD, 0.5 inch free length, closed and ground end spring with a 7 pound per inch spring rate.

Installation Notes

Installation is performed by qualified mechanical or equipment service technicians. Depressurize and de-energize any assembly before removing or replacing springs. Verify that the post or shaft diameter does not exceed the hole diameter of 0.187 inches to prevent binding. Do not stretch or compress the spring beyond its rated solid height or maximum work load during installation.
