HYM40-1447 - Pipe Plug

One New Aftermarket Replacement Pipe Plug (O-Ring Type) for Caterpillar (Cat) Construction Equipment

This aftermarket replacement plug is an O-ring-sealed hydraulic pipe plug used across a wide range of Caterpillar (Cat) construction and industrial equipment. It seals hydraulic ports and passages in hydraulic pumps, motors, cylinders, valves, and related assemblies. The plug uses a 7/16-20 thread with an O-ring seal rather than a tapered pipe thread, providing a reliable leak-free seal in hydraulic systems. Replaces Caterpillar OEM part number 9S8002 and Interstate McBee cross-reference M-9S8002.
