The Hoopster retaining rings fit into much shallower grooves than regular snap rings or retaining rings. The Hoopster's low profile, precision circularity, and small radial size allow it to be an unobtrusive component in an assembly. The rings are suitable for light to heavy loads, ideal for thin wall tubes, and have a high thrust capacity. The low radial profile will not twist or deform under load as with conventional retaining rings. Easily installed without special tools, the rings come in sizes from 3/8" to 3.0" and are offered in carbon and 302 stainless steel.
