Gardner Spring 36029GS Precision Compression Spring

Product Description

The GARDNER SPRING 36029GS is a precision compression spring manufactured from stainless steel and designed for applications requiring consistent, repeatable force across a compressed range. It features a 0.24 inch outside diameter, a free length of 0.875 inches, and a wire diameter of 0.026 inches. The spring delivers a maximum work load of 4.57 pounds and a spring rate of 6.96 pounds per inch. Closed and ground ends provide stable seating and uniform load distribution. This spring suits technicians and engineers working on HVAC equipment, plumbing valves, electrical components, and light mechanical assemblies where tight tolerances are required.

This compression spring is sized for installations where small-form, high-precision springs are needed inside control valves, actuators, pressure regulators, relay contacts, and similar assemblies. Its stainless steel construction resists corrosion in wet or chemically active environments, making it appropriate for plumbing, pool equipment, and outdoor HVAC applications. The solid height of 0.287 inches and a hole diameter fit of 0.25 inches help guide fitment selection during assembly or replacement service work.

Key Features

• Closed and ground ends for consistent, flat seating and accurate load transfer
• Stainless steel construction provides corrosion resistance in wet and chemically active environments
• Spring rate of 6.96 pounds per inch supports precise force calibration in small assemblies
• Maximum work load of 4.57 pounds suits light-duty valve, relay, and actuator applications
• Plain silver finish; no coating to interfere with tight clearance fits
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed as an OEM-style precision compression spring for use in small mechanical assemblies, control valves, actuators, and similar components requiring a 0.24 inch OD and 0.875 inch free length spring.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified mechanical assemblers depending on the host assembly. Always de-energize or depressurize the host system before disassembling spring-loaded components. Verify spring seating surfaces are clean and free of debris to ensure the closed ground ends seat squarely. Do not compress the spring beyond its solid height of 0.287 inches during installation.
