    Ultra-Seal is Mr. Gasket's premium valve cover Gasket material.

    It's manufactured from a high density cork and rubber blend with a black latex coat applied to the outside to help seal minor flange irregularites and eliminate oil leakage. It creates a positive seal by controlled swelling of the Gasket material when exposed to hot oil.

    For OE replacement, high performance street, drag race and oval track use. Sold as a pair, these Gaskets are .187 inch thick.
