APSOseal® Flat Gaskets

Flat gasket solutions and products from a single supplier In all areas of industry, sealing issues arise wherever substances and process fluids are handled, transported or stored. In the chemical industry, in refineries, in the energy production and conversion sector and in the food-and-beverage industry, inconspicuous or even invisible flat gaskets often have key importance. Since gaskets in their various areas of deployment are subjected to a wide range of different strains and stresses, numerous different materials with properties that deviate widely from each other are used to manufacture...
