Packing Style 2235 is composed of layers of flexible graphite tape plied into compact strands; each filament is reinforced with an Inconel® wire jacket. The strands are then square braided to form a dense yet malleable packing. Additionally, it is also impregnated with a minimal amount of lubricating agents to reduce stem friction.
Style 2235 is self-lubricating, non-hardening, dimensionally stable and resistant t well as heat, pressure and chemicals. The Inconel® filament jacket affords mechanical stability and extrusion proof, while the advanced construction provides leakage control and high integrity in steam service.
Due to it's physical properties and ability to minimize friction, 2235 is ideal for valves and broad range of applications. It is well suited for power plants, refineries, petrochemical in processing as well as sealing applications in steam at high pressure and temperature.
