products_spiral_01 Due to its sturdy design, the spiral wound gasket is simple to install without causing damage. The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out. By combining different winding materials and metals, the gasket can be tailored to a wide variety of operating conditions. Due to its non-adhesive character, the gasket is easy to remove after service. The SWP gasket does not cause any damage to the flange faces.
