2 sheets. Each sheet is approx. 11" x 12" and is in excellent condition. This material is far superior to the gasket material available in auto parts stores and hardware stores.

ACCOSEAL products are especially effective in metal-to-metal joints where a gasket fits into a machined groove in a flange. Because of cork's inherent cell structure, no allowance for side flow is needed. Compressible ACCOSEAL cork and rubber materials can take the place of more expensive (and non-compressible) molded rubber O-rings. Additional benefits of Accoseal products include:

ACCOSEAL materials retain some of the friction of cork, which helps to reduce slippage or extrusion of gaskets.
ACCOSEAL cork and rubber materials will easily conform to poor surface conditions and compensate for minor flange irregularities. This is especially helpful for applications where the bolt load is low.
ACCOSEAL materials exhibit excellent resilience, which provides resistance to compression set and other fatigue effects. ACCOSEAL cork and rubber gaskets are more resistant to aging than standard rubber gaskets.
