A112 piston seals are three piece double acting piston seals which consist of two POM back-up rings and a NBR sealing ring.
Dynamic surface of NBR part is fabric reinforced to have better mechanical properties and friction characteristics.
These seals are highly popular in metal industry and earth moving equipments.
