Plastic Back-Up Rings
Similar to washers, back-up rings are also known as anti-extrusion rings, providing an effective barrier that eliminates the unwanted extrusion of seals into and through gaps. Here at R & B Plastics, we use the most current and accurate CNC equipment to manufacture plastic back-up rings. Short runs and large orders are welcome – we meet our customers’ unique requirements fast.
