Gardner Spring 36254G Precision Compression Spring

Product Description

The GARDNER SPRING 36254G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It measures 0.18 inches outside diameter and 1 inch free length, with a wire diameter of 0.022 inches. The spring delivers a rate of 6.3 pounds per inch and a maximum working load of 3 pounds (17.79 N). End type is closed and ground, which provides a flat seating surface and consistent load transfer. This part is used in light-duty mechanical assemblies across HVAC, plumbing, electrical, and general equipment maintenance applications where a small, precise compression spring is required.

The 36254G suits applications requiring a compact compression spring with consistent rate and load characteristics. Its small outside diameter of 0.18 inches and 1-inch free length make it appropriate for use inside control mechanisms, valve assemblies, switch components, and similar tight-clearance installations. The closed and ground ends allow it to seat squarely in bores or against flat surfaces, supporting repeatable force delivery. Technicians servicing HVAC equipment, plumbing valves, or electrical control assemblies will encounter this spring type in a range of OEM and aftermarket configurations.

Key Features

• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Closed and ground end type for flat, stable seating and accurate load transfer
• Spring rate of 6.3 pounds per inch for predictable, linear compression behavior
• Maximum working load of 3 pounds (17.79 N)
• Solid height of 0.368 inches; recommended hole diameter of 0.188 inches
• Plain silver finish - no coating to affect dimensional tolerances

Compatibility

Designed as an OEM-style precision compression spring suitable for use in valve assemblies, control mechanisms, and light-duty mechanical equipment requiring a 0.18-inch OD, 1-inch free length music wire spring.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or electricians as part of component-level repair or assembly work. De-energize equipment and relieve any system pressure before accessing spring-loaded assemblies. Verify that the bore diameter accommodates the 0.188-inch recommended hole diameter and that the seating surfaces are clean and undamaged. Do not stretch or compress the spring beyond its rated working load during installation.
