The LGR gaskets offer an excellent performances for sealing the bonnet flanges of the valves and for sealing the heat exchangers. Improved permeability resistance can be achieved with the inner eyelet. For a perfect seal with this gasket it is recommended to use a thickness of 1.5 mm.
Flexible graphite C > 98,00% with smooth stainless steel core.
Graphite gasket for bonnet flanges and heat exchangers. The graphite doesn't work with oxidizing fluids.
