One New Aftermarket Replacement Backup Ring for Caterpillar (Cat) Equipment
This aftermarket backup ring replaces Caterpillar (Cat) OEM part number 1838068. Backup rings are anti-extrusion devices installed alongside O-rings and other elastomeric seals in hydraulic and sealing systems. They are used in high-pressure static and dynamic sealing applications -- such as hydraulic pumps, cylinders, valves, and engine systems -- where pressure surges could otherwise cause seal extrusion and premature failure. The backup ring bridges the seal groove and mating surface, protecting the primary seal and extending overall sealing system life.
