V-ring, used on back-up rolls of hot and cold rolling mills. Version VA8-A, standard Version VA8-B, with friction optimised sealing lip of PTFE Furthermore, they have a stiffening metal ring inside, enabling an assembly in open housing. The standard production is a Nitril elastomer NBR added with PTFE, but for particular working conditions, V-rings type VA8 can also be produced in HNBR hydrogenated nitrile elastomer.
