Low-Friction Oil- and Water-Resistant Packing Seals

These seals require lighter packing pressure than standard oil- and water-resistant packing seals, so they cause less friction and reduce shaft wear. They’re made of graphite-impregnated aramid fiber and are for use in pumps and valves. Cut these seals to size with a knife; then pack them into place.

Heat-Shielding Oil- and Water-Resistant Packing Seals

Synthetic yarn that’s comparable in strength to aramid is combined with graphite for soft seals that dissipate heat away from the shaft to extend the life of pumps. Cut these seals to size with a knife; then pack them into place.
