Garter Springs are helical coil springs whose ends are connected together to form a circular shape to provide a strong Radial Force. Compression garter springs exert outward radial forces, while extension garter springs exert inward radial forces. They can easily handle pressure, viscosity, and temperature changes and prevent contamination from water, dust, dirt, lubrication, and chemicals. They can be supplied pre-assembled into loops, or in lengths – this is particularly useful for standard weights or diameters, as it allows you to cut and assemble your garter springs as needed.
