Gardner Spring 36076G Precision Compression Spring

Product Description

The GARDNER SPRING 36076G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It features a 0.42-inch outside diameter, a free length of 0.875 inches, and a wire diameter of 0.042 inches. The spring delivers a maximum work load of 11 pounds and a spring rate of 18.5 pounds per inch, making it well-suited for applications that require consistent, repeatable force within a compact envelope. End type is closed and ground for stable seating and accurate load transfer. The plain silver finish indicates no additional coating. Maintenance technicians, OEM assemblers, and mechanical engineers working across HVAC, industrial, and general mechanical applications install this spring type.

This spring fits applications where a small-diameter, short-length compression spring is needed to manage light to moderate loads. Typical use scenarios include valve assemblies, actuator mechanisms, switch returns, and precision instrument components found in residential and commercial HVAC equipment, plumbing valve bodies, and general industrial machinery. The compact solid height of 0.285 inches allows installation in tight axial spaces where larger springs cannot fit.

Key Features

• Closed and ground ends provide flat, stable bearing surfaces for accurate load application
• Music wire construction (ASTM A228 / ASTM A313) delivers high tensile strength and fatigue resistance
• Spring rate of 18.5 pounds per inch supports precise force control across the travel range
• Outside diameter of 0.42 inches fits into holes up to 0.437 inches in diameter
• Compact solid height of 0.285 inches suits confined installation spaces
• Plain finish maintains dimensional consistency without coating buildup

Compatibility

Designed as an OEM-style precision compression spring for use in HVAC, plumbing, and general mechanical assemblies requiring a 0.42-inch OD closed-and-ground music wire spring.

Installation Notes

Installation is performed by qualified technicians or mechanical assemblers familiar with spring-loaded valve and actuator assemblies. Disengage all pressure, power, or stored-energy sources in the assembly before replacing or inserting the spring. Verify that the mating bore diameter does not exceed 0.437 inches and that axial alignment is maintained to prevent side-loading, which can reduce spring life. Do not compress the spring past its solid height of 0.285 inches during installation or testing.
