Patricularly suitable for use with hydrofluoric acid, but not pure hydrogen fluoride. Best for use with string alkalis, solvents, fuels, water, steam and chlorine. Other applications include solvents, fuels, water, oil, chlorine and caustics. A chemical resistance list is available upon request.
Flange gaskets and sheets are available in thickness of 1/32″,1/16″, 1/8″. Other thicknesses available on request. Standard gaskets can be supplied in accordance with ASME B16.21. Non-standard or special gaskets can be manufactured according to customer drawings, or by given sizes or Edrawing.
Can be used from -240°C to approx. 270°C, depending on the installation and operating conditions
