Gardner Spring SS-13M Utility Compression Spring

Product Description

The GARDNER SPRING SS-13M is a utility-grade compression spring manufactured from stainless steel with a plain finish. It measures 0.500 inches in outside diameter and 2.000 inches in free length, with a wire diameter of 0.047 inches and a solid height of 0.700 inches. The spring delivers a rate of 5.85 pounds per inch and supports a maximum working load of 3.56 pounds. Closed ends provide stable seating in standard spring pockets and retainers. HVAC technicians, plumbers, electricians, and mechanical contractors use utility compression springs like this in valve assemblies, damper linkages, control mechanisms, and general equipment service work.

The SS-13M is suited for light-duty mechanical applications where a compact, corrosion-resistant compression spring is required. Its stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact. The closed-end design fits standard counterbored pockets and flat mounting surfaces. Typical applications include residential and light commercial HVAC equipment, plumbing valve components, electrical enclosure hardware, and general-purpose mechanical assemblies requiring a 0.500-inch OD spring in this load and rate range.

Compatibility

Designed as an OEM-style utility compression spring replacement for mechanical assemblies requiring a 0.500-inch OD, 2.000-inch free length, closed-end compression spring in stainless steel.

Installation Notes

Compression springs should be installed by qualified mechanical, HVAC, or plumbing technicians familiar with the equipment being serviced. Always de-energize and depressurize the system before replacing spring components in valve or damper assemblies. Verify the spring pocket depth and seating diameter against the solid height and outside diameter before installation to ensure proper fit and travel. Do not compress the spring beyond its solid height during installation or operation.
