CONSTRUCTION
Style 2202 packing is diagonally braided from pure, expanded flexible graphite, reinforced at the corners and throughout with high-quality carbon fibers. The carbon fiber reinforcement in the corners and body of the packing make it three times more resistant to extrusion and also increase the pressure handling capabilities compared to non-reinforced flexible graphite packing.
APPLICATION/SERVICE
Style 2202 This extremely versatile packing can be used in many demanding applications, both dynamic and static. This style packing is particularly suited for high temperature and high pressure serivce in valves, pumps, expansion joints, mixers, and agitators. It can handle most chemicals in the 0-14 pH range with the exception of strong oxidizers.
