Graphite gaskets for flanges in low pressure services.
Pure flexible graphite C > 98.00 % covered on both side with 2 special polimeric films. Planigraph ™ Metalbond Evo 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.
Planigraph™ Metalbond Evo pure graphite gaskets are great for sealing flanges in low pressure services. These gaskets style Metalbond Evo thicknesses 2.0 and 3.0 mm with stainless steel inner eyelet which are suitable for application intended in contact with food applications.
