One New Aftermarket Replacement O-Ring Seal for Caterpillar (Cat) Equipment
This aftermarket replacement O-Ring Seal (Seal-O-Ring) is a precision-fit sealing component used in the fuel transfer pump system on Caterpillar (Cat) equipment. O-ring seals in fuel transfer pump assemblies maintain a leak-proof barrier between mating surfaces, preventing fuel loss and protecting system pressure. Replacing a worn or damaged o-ring at service time helps avoid fuel leaks and unplanned downtime on the job site.
