SEPCO Grafoil Gasket Sheet, Graphite

Sepco’s Grafoil gaskets provide leak-free performance at moderate bolt loads, with no cold flow or creep. They eliminate precision bolt tightening and flange sticking. In fact, the prime requirement for satisfactory sealing with Grafoil gaskets is sufficient unit load on the gasket at all times and at all points on the gasket. If surfaces are maintained flat within 0.005 in and are held to a surface finish of 125 RMS or better, the gaskets will seal hydrystatic pressures.
