The first rubber steel gasket

After the successful establishment of NILOS in the field of conveyor equipment, mining expertise and practical knowledge once again solve a new challenge: the first G-ST Ring (Rubber-Steel Flange gasket) is developed. The previously used fragile rubber ring is stabilized by a steel insert. The outer diameter of the ring automatically centers itself in the flange on the bolt circle. Additional benefits include the rounded shape and steel insert, providing better sealing performance and suitability for higher pressures.
