A comb-like two-sided overlain gasket for sealing of dismountable flanged joints includes two sealing contact surfaces. Each contact surface defines a plurality of V shaped concentric grooves. Each of the V shaped grooves has an opening angle of 90 degrees. Each of the contact surfaces includes concentric surfaces that are disposed between each of the grooves. The concentric surfaces are created in a single plane and include a constant width that ranges from 0.2 mm to 0.6 mm. A bottom portion of the concentric grooves are rounded and have a radius that ranges from 0.3 mm to 0.5 mm. The comb-like two-sided overlain gasket also includes one of a sealing foil or a sealing plate that overlays the sealing contact surfaces and that extend beyond the concentric grooves. When compressed, the concentric grooves define a smaller volume than the volume of the sealing foil or the sealing plate.
