Gardner Spring 36118G Precision Compression Spring

Product Description

The GARDNER SPRING 36118G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It measures 0.72 inches outside diameter and 1.25 inches free length, with a wire diameter of 0.063 inches and a solid height of 0.411 inches. The spring delivers a rated spring rate of 19 lb/in and handles a maximum work load of 15.5 pounds. Closed and ground ends provide stable seating and consistent load transfer. Maintenance technicians, OEM assemblers, and field service professionals across HVAC, plumbing, and general mechanical trades rely on this style of precision spring for consistent performance in compression applications.

The 36118G is suited for residential and light commercial mechanical assemblies where a small-diameter, short-stroke compression spring is required. Typical installation scenarios include valve assemblies, actuator mechanisms, pump components, and equipment latching systems. Its 0.75-inch hole diameter fit and music wire construction make it appropriate for applications requiring reliable cyclic load performance within the spring rate and load specifications listed.

Key Features

• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 19 lb/in spring rate for predictable, linear load response
• 15.5-pound maximum work load capacity
• Plain silver finish suitable for general mechanical environments
• Compact form factor: 0.72 inches OD and 1.25 inches free length

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.72-inch outside diameter, 0.75-inch hole diameter fit, and 1.25-inch free length within the 19 lb/in spring rate range.

Installation Notes

Installation is typically performed by mechanical assemblers, HVAC technicians, or plumbing professionals during component repair or OEM assembly. Verify that the mating bore diameter and spring pocket depth match the hole diameter and solid height specifications before installation. Depressurize or de-energize any system before replacing compression springs in valve or actuator assemblies. Do not compress the spring beyond its solid height during installation or operation.
