This kind of gaskets is obtained by pressing a graphite tape, leading it to the required density.

The rings con be realised in large diameters and thícknesses to satisfy any seal demand far applications on pumps, valves and alternative movements.

Far uses in which there is more stress, such as anti-extrusion rings, these qaskets con be realised with the addition of an AISI 30,4 steel net, pressed together with the graphite tope.
They con be provided endless or cutted (specially useful far an easy replacement).
