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.

Abrasion-, Oil-, and Water-Resistant Packing Seals

The most abrasion resistant of all our packing seals, these are made of PTFE-impregnated aramid fiber that has been saturated in a lubricant. They are for use in pumps. Cut these seals to size with a knife; then pack them into place.
