The Stemco ZST330-3067 Hub Cap Gasket - Multi Hole Heavy Duty is a robust wheel-end sealing solution for commercial and trailer axle applications using 5-1/2-inch bolt circles. This heavy-duty gasket suits hub caps with both 5 and 6 mounting holes, providing a reliable seal to help prevent debris penetration and lubricant escape in demanding service. Manufactured from high-grade gasket material, it is engineered to handle minor spindle imperfections and promote positive spindle seating, supporting long service life in fleet and heavy transport environments. The gasket features a 5-1/2-inch bolt circle and 5/16-inch mounting bolt holes, with a multi-hole layout that offers flexible fitment across compatible hub cap designs. Its construction is intended for use on wheel-end and trailer axle hub caps where consistent sealing performance is required. This part is supplied individually, making it suitable for both single-axle repairs and larger maintenance programs where specific hub cap gaskets are being replaced.
