The Metal Tech “Corseal” series features a rectangular perforation pattern. This pattern has nearly twice the perforations per square inch as the starburst pattern, providing more contact points to grip the facing. It should be used for gaskets where land area is tight to be sure that there is a bond point in the cross section. This core also compresses at lower loads resulting in approximately 10% more compressibility over the same facing on the Hi-Tex core. This is advantageous when designing head gaskets or other critical fluid sealing gaskets. This core technology is commonly used for head gaskets, intake gaskets, engine fluid gaskets, cover gaskets, and general industrial flange gaskets.
