These materials consist of cork bonded with nitrile rubber.

The structure of these materials, which are resistant to oils and fuels, ensures high compressibility and recovery.

RGC 210
Sight glass gaskets, for sealing glass to metal or ceramic to metal, cover gaskets for lightweight containers where good resistance to oils, fuels and solvents is required.

RGC 257
Sight glass gaskets, gaskets in glass/metal combinations, cover gaskets for lightweight containers where good resistance to oils and aromatic solvents is required.

RGC 275
For sealing oil-filled transformers, hatch covers of tanks and fuel bunkers in the shipbuilding industry, etc.
