GR48 Manhole Gasket


GR 48 is an oval gasket made of high-temperature glass fabric reinforced with brass filaments impregnated with nitrile rubber and graphitized on the surface.

The cloth is cut diagonally in sectors, rolled up, and pressed.

The diagonal cut of the fabric and the careful workmanship in only one piece ensures a stable form and a close sealing of the manhole.

The gasket is resistant to most oils and solvents.
