Brown NBR rubber delivers reliable wear resistance and good compatibility with mineral engine oil and gear lubricants.
The stepped dual height profile 9/19 mm fits housings requiring special two-stage installation geometry.
Imperial marking 3.251-4.249-0.335/0.709 inch supports cross reference for customers using inch dimension catalogs.
This seal is an aftermarket replacement part; verify shaft, bore and working condition before order.
