24990-52 Cork seal check valve

This James Gaskets cork seal is designed for the check valve body located in the crankcase, specifically fitting around the tappet oil screen. Sold as a pack of ten, it is a direct replacement for OEM 24990-52 and is designed for 1952 to 1965 Panhead models. Cork is the traditional material for this application, providing the necessary compressibility to create a positive seal in the oiling system. Ensuring this check valve is properly sealed is vital for maintaining correct oil pressure and preventing oil from draining back into the crankcase when the bike is parked, a common issue on vintage Panheads.
