Hunger seals and bearing elements are manufactured exclusively from high-quality materials. The elastic elements of the seals are made of wear-resistant polyurethane or special elastomeric compounds (nbr, fpm, epdm, ...). Where economically and technically feasible, PTFE or PTFE compounds are used in seals or to produce complete seals. The use of PTFE can, among other things, increase the service life and efficiency of the equipment. All types of Hunger seals are available... these are only original hunger seals (not aftermarket).
