Gardner Spring SS-20M Utility Compression Spring Stainless

Product Description

The GARDNER SPRING SS-20M is a utility compression spring manufactured from stainless steel and intended for general mechanical and industrial applications. It features a 0.75 inch outside diameter and a 3.13 inch free length, with a wire diameter of 0.091 inches. The spring delivers a rate of 27.5 pounds per inch and supports a maximum working load of 37.18 pounds. Closed ends provide stable seating against mating surfaces without additional hardware. Licensed technicians and maintenance professionals working with HVAC equipment, fluid handling assemblies, or mechanical subcomponents will encounter this spring type in valve stacks, damper linkages, and actuator returns.

This spring is suited for light to medium-duty compression applications across residential and commercial mechanical systems. Its stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact, including pool and spa equipment housings, plumbing valve assemblies, and HVAC component brackets. The plain finish requires no additional prep before installation. Sold in packages of six units, making it practical for shop stock or service van inventory.

Installation Notes

Installation is performed by qualified mechanical, HVAC, or plumbing technicians as part of a subassembly repair or replacement. Isolate and de-energize or depressurize the host system before disassembling any spring-loaded component. Verify that the replacement spring seats fully and concentrically within the bore or against the retaining surface before reassembling. Do not stretch or compress the spring beyond its solid height during handling.
