Ultra-Seal material provides a positive seal through controlled swelling of the gasket once exposed to hot engine oil.
The polymers used in Ultra-20 also insure gaskets will not harden and fall apart like others can. Gaskets are coated with an easy release material which helps prevent tearing when the valve covers are removed.
