Flexible Graphite High Temp Braided Packing – Graphite Yarn, Graphite Filled
This packing is a rugged premium grade, low friction, high strength, graphite fiber. It contains a special lubricant to provide a bearing film and protect shafts from scoring and acts as a blocking agent to prevent wicking.

Application:  Handles strong acids and alkali solutions except fuming nitric acid, oleum and fluorine. It can be used to seal steam, water, oil, solvents, alkalis, and acids.

Economical High Temp Braided Packing – Carbon Yarn, Graphite Filled 
This packing is manufactured from pure carbon yarn impregnated with lubricants and graphite particles. This construction helps fill voids, block leakage, and acts as a break-in lubricant. This packing has a low coefficient of friction and tends to wear more evenly than most braided packing.

Application: Handles water, steam, boiler feed, and aqueous solutions of acids and alkalis. This style is commonly used for high speed pumps, blowers, dryers, high temperature valves, and furnace gaskets.

PTFE – FDA Braided Packing – Pure PTFE Yarn, FDA Approved 
This packing is a firm, pliable braided packing made from the purest PTFE (Teflon®) filaments. A food-grade lubricant provides faster break-in and reduced shaft wear. Complies with the FDA and USDA requirements under Title 21 Food and Drugs: 
     Part 177.1500 – Perflourocarbon Resins 
     Part 178.3570 – Lubricants with Incidental Food Contact

Application:  Resists most caustic media and is commonly used in centrifugal and rotary food processing equipment. It is also used in blenders, mixers, cookers, dryers and pumps.

GFO – PTFE Braided Packing – Expanded PTFE / Graphite
This packing utilizes PTFE/graphite yarn and a high temperature break-in lubricant. The yarn is formed from expanded PTFE in which fine particles of pure graphite have been encapsulated. The resulting product combines the chemical resistance of PTFE with the heat dissipation characteristics of graphite.

Application:  Chemically inert over the entire 0-14 pH range with these exceptions: molten alkali metals, flourides, aleum, fuming nitric acid, aqua regia, and other strong oxidizing agents. Commonly used in pumps, valves, rotating and reciprocating shafts, mixers and agitators, and is especially designed for services involving surface speeds and temperatures higher than those that can be handled by pure PTFE packing.

PTFE (Teflon®) Braided Packing – Synthetic Yarn Lubricated with PTFE
This packing uses synthetic yarns thoroughly impregnated with PTFE. The finished packing is again coated with PTFE and a break-in lubricant is added to reduce shaft wear and eliminate glazing at start up.

Application: An excellent multi-service packing that handles steam, water, solvents, oils, mild acids and alkalies, and a broad range of other chemicals. It is white in color and will not discolor the flow media. This style is recommended for use in centrifugal, rotary and reciprocating pumps and also mixers, agitators, and expansion joints.

Graphite Lubed Braided Packing – Synthetic Yarn, Graphited, and Lubricated
This packing utilizes synthetic yarns thoroughly impregnated with a petroleum based lubricant and graphite.

Application:  A dense, but flexible general service packing that adapts well to worn or scored shafts often found in older equipment.  Excellent against steam, brine, oil, and mild acids and alkalis. Well suited for applications in rotary and centrifugal pumps and some valves.
