Non Asbestos Sheet Y Grade (Own Brand)


V300 non-asbestos gaskets are manufactured from Corseal's own medium-duty gasket material. 

Owing to its natural rubber content, the sheet is flexible and adapts more easily to curvatures and irregularities of the flanges. Specially recommended for water and steam systems, both in heating engineering, power engineering and municipal economy. The sheet is resistant to oils, brake fluid and cooling fluid.
