Planigraph™ Metalbond LGPC

Composition

Graphite gaskets for 150-300 psi flanges.

Characteristics

Pure flexible graphite C > 98.00 % covered on both side with 2 special polimeric films. Planigraph ™ Metalbond LGPC pure graphite flat gaskets are excellent substitutes of CSF gaskets - Compressed Synthetic Fibers - thanks to their smaller creep and for their moderate sensitivity to the thermal cycles.

Applications

Planigraph™ Metalbond LGPC pure graphite gaskets are great for sealing flanges 150 to 300 psi classes. These gaskets style Metalbond LGPC thicknesses 2.0 and 3.0 mm with stainless steel inner eyelet which are suitable for application intended in contact with food applications.
