National Oil Seal # 21901

[Texas Diesel]

I need information on this seal so I can cross reference it by dimensions.



Any suggestions?

Get a National Seal catalog. They list dimensions in there, I believe.

Thanks for the effort but my seal is way smaller than that. Must be an old part number or some such stupidity.
