Some applications demand seals with radial and axial sections larger than normally used, e.g. in hydraulic cylinders subjected to vibrations. Type AG is an appropriate solution for such applications (fig 1).
V-seal set of fabric reinforced materials can in many applications be replaced by type AG. The central sealing ring of type AG is manufactured of nitrile rubber, the bottom ring of a polyester elastomeric material and the back-up ring of acetal resin.
