APG’s Style 1176 pump packing contains a unique combination of amorphous carbon fibers (PAN fibers) treated throughout with fine particles of graphite. It is an excellent alternative in applications where asbestos packings are not permitted and graphite yarn packings are too expensive. Style 1176 is recommended for operating temperatures up to 850°F / 454°C and shaft speeds up to 4000 feet per minute for general service on rotary and reciprocating shaft and as end rings on high-temperature valves in chemical services in which carbon is suitable.
