Value Collection 03308418 Compression Spring Stainless Steel

Product Description

The VALUE COLLECTION 03308418 is a stainless steel compression spring designed for applications requiring reliable, consistent return force in a compact envelope. With an outside diameter of 0.42 inches, a free length of 1 inch, and a wire diameter of 0.047 inches, this spring delivers a spring rate of 17.57 pounds per inch and a maximum working load of 9.46 pounds. The stainless steel construction provides corrosion resistance suitable for demanding mechanical, industrial, and fluid-handling environments. Maintenance technicians, mechanical assemblers, and trade professionals working on HVAC equipment, plumbing valves, or related assemblies will find this spring a direct-fit solution for standard spring pockets.

This compression spring is suited for use in light-duty mechanical assemblies where a small-diameter, short-travel spring is required. Typical applications include valve actuators, pressure-relief mechanisms, damper linkages, and general mechanical subassemblies in residential and commercial trade equipment. The 0.4375-inch hole diameter clearance fit and 0.395-inch solid height allow it to seat in standard machined pockets without modification. Sold in a package quantity of 10, it is appropriate for bench stock, service kits, or small production runs.

Key Features

• Stainless steel construction for corrosion resistance in wet or harsh environments
• Spring rate of 17.57 pounds per inch for predictable, linear deflection behavior
• Maximum working load of 9.46 pounds suits light-duty valve and actuator applications
• Outside diameter of 0.42 inches fits standard 0.4375-inch (7/16 inch) bore pockets
• Solid height of 0.395 inches limits compression travel and prevents coil bind
• Package quantity of 10 supports bench stock and service kit replenishment

Compatibility

Designed as a general-purpose OEM-style compression spring for mechanical assemblies requiring a 0.42-inch OD, 1-inch free length spring with a 17.57 pounds-per-inch rate in stainless steel construction.

Installation Notes

Installation should be performed by a qualified technician familiar with the host assembly. Relieve all system pressure and de-energize any associated electrical circuits before disassembling valve bodies, actuators, or spring-loaded mechanisms. Verify the installed spring seats squarely in the bore pocket and is not laterally deflected before closing the assembly. Consult the host equipment service manual for any preload or compression-depth requirements specific to that assembly.
