Gardner Spring 36389GS Precision Compression Spring

Product Description

The GARDNER SPRING 36389GS is a precision compression spring manufactured from stainless steel to AISI 302, ASTM A228, and ASTM A313 standards. It measures 0.3 inches in outside diameter with a free length of 0.5 inches and a wire diameter of 0.0449 inches. The spring delivers a rated spring rate of 78.26 pounds per inch and supports a maximum work load of 20 pounds (76.35 N). Closed and ground ends provide stable seating and consistent load transfer. This part is suited for applications requiring repeatable force characteristics in a compact form factor and is typically installed by mechanical technicians, maintenance professionals, and precision assembly technicians.

The 36389GS fits applications where a small-diameter, short-length compression spring is required, including HVAC equipment assemblies, valve mechanisms, actuator components, and general industrial hardware. Its stainless steel construction makes it appropriate for environments where corrosion resistance or exposure to moisture is a concern. The closed and ground end type ensures flat, square seating against mating surfaces, which is important in precision load or actuation scenarios.

Key Features

• Closed and ground ends for flat seating and consistent load application
• Stainless steel construction for corrosion resistance in demanding environments
• Spring rate of 78.26 pounds per inch for predictable deflection under load
• Maximum work load rated at 20 pounds (76.35 N)
• Compact geometry: 0.3 inches OD, 0.5 inches free length, 0.2710 inches solid height
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed as a precision replacement or OEM-style compression spring for applications requiring a 0.3-inch outside diameter and 0.5-inch free length closed-and-ground spring in stainless steel construction.

Installation Notes

Compression springs of this type are installed by mechanical technicians and assembly professionals working on valves, actuators, or equipment sub-assemblies. De-energize and isolate the system before removing or installing any spring component. Verify seating surfaces are clean and free of debris to ensure square load application against the closed and ground ends. Do not compress the spring beyond its solid height of 0.2710 inches during installation or operation.
