APG’s Style 1178 pump packing is constructed of non-asbestos aramid fibers which are a synthetic fiber displaying many characteristics of asbestos. Each stand is individually treated with a PTFE coating and a light, inert oil which fills and seals interstices in the packing fibers then is forced air-dried. This packing will not wick. Style 1178 is recommended for operating temperatures up to 500°F / 260°C and shaft speeds up to 1900 feet per minute in general service, caustics, mild acids, chemicals, air, oil, gases, solvents and general chemical plant applications for rotating and reciprocating shafts and all equipment on which braided asbestos packings are used. This product is a great performer in extreme abrasive environments.
