Gardner Spring SS-1M Utility Compression Spring 1.25in Od

Product Description

The GARDNER SPRING SS-1M is a utility compression spring manufactured from stainless steel for corrosion resistance in demanding service environments. It features a 1.25-inch outside diameter and a 3-inch free length, with a wire diameter of 0.148 inches and a closed end type for stable seating. The spring delivers a rate of 64 pounds per inch and a maximum working load of 81.95 pounds. It is suited for mechanical assemblies, HVAC equipment, plumbing fixtures, and general industrial applications where a reliable, consistent spring force is required. Licensed tradespeople and maintenance technicians working across multiple trades commonly stock this size.

This compression spring fits residential and light commercial applications where a mid-range load capacity and compact form factor are needed. Typical install scenarios include valve actuators, pump assemblies, access panel latches, damper linkages, and equipment mounting brackets. The stainless steel construction makes it appropriate for wet or corrosive environments such as pool equipment enclosures, condensate systems, and outdoor mechanical panels. The plain finish and silver color indicate no additional protective coating, which is standard for stainless utility springs.

Key Features

• Stainless steel construction resists corrosion in wet and outdoor service environments
• 1.25-inch outside diameter with closed ends for consistent seating and load transfer
• 64 pounds per inch spring rate provides predictable, linear deflection response
• 81.95-pound maximum working load suitable for medium-duty mechanical assemblies
• 1.48-inch solid height allows for significant compression travel within a compact envelope
• Plain finish with no coating - compatible with most mechanical interface materials

Compatibility

Designed as an OEM-style utility compression spring for mechanical assemblies requiring a 1.25-inch outside diameter, 3-inch free length, and closed end configuration across HVAC, plumbing, pool, and general industrial equipment.

Installation Notes

Compression springs of this type are installed by HVAC technicians, plumbers, and mechanical maintenance personnel. Before replacing a spring in any pressurized or powered assembly, de-energize the equipment and relieve any system pressure or stored mechanical load. Use appropriate hand tools to seat the spring squarely against both mating surfaces to ensure even load distribution and prevent binding. Verify that the replacement spring rate and outside diameter match the original specification before reinstalling any retaining hardware.
