Oil- and Water-Resistant Packing Seals

Made of PTFE-impregnated synthetic fiber, these seals are for use in pumps. They're lubricated to prevent overheating. 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.
