Gardner Spring SS-7M Utility Compression Spring Stainless

Product Description

The GARDNER SPRING SS-7M is a utility compression spring manufactured from stainless steel and intended for general-purpose mechanical and industrial applications. It features a 0.375 inch outside diameter and a 1.75 inch free length, with a wire diameter of 0.041 inches. The spring rate is 8.31 pounds per inch, and the maximum working load is 7.65 pounds. Closed ends provide stable seating against flat surfaces. This type of spring is commonly installed by maintenance technicians, mechanical contractors, and trade professionals working on equipment that requires consistent, repeatable compression force across a compact form factor.

The SS-7M suits light-duty compression applications where a small-diameter, stainless steel spring is required for corrosion resistance and consistent load performance. Typical use cases include valve assemblies, fluid handling equipment, HVAC controls, plumbing fixtures, and general OEM mechanical assemblies. The plain finish and silver color indicate an uncoated stainless surface. This spring is sold in packages of six units, making it practical for service technicians stocking common hardware sizes.

Key Features

• Closed end type ensures flat, stable contact against mating surfaces

Compatibility

Designed as a general-purpose utility compression spring suitable for OEM and replacement use in mechanical assemblies, valve components, HVAC controls, and plumbing equipment requiring a 0.375 inch OD, 1.75 inch free length stainless steel compression spring.

Installation Notes

Installation is typically performed by a qualified mechanical, HVAC, or plumbing technician as part of a component service or assembly procedure. Always de-energize and depressurize the affected system before disassembling any spring-loaded component. Verify that the spring seats flush against both mating surfaces and that the installed length falls within the equipment manufacturer's specified working range. Do not compress the spring beyond its solid height during installation.
