Low-Friction Oil- and Water-Resistant Packing Seals

Since they require lighter packing pressure than standard oil- and water-resistant packing seals, these seals cause less friction and reduce shaft wear. They are for use in pumps and valves. Cut them to size with a knife; then pack them into place.

Packing Seal Tape


Plain Backing	Adhesive Backing

For use in valves and pumps, this thin, flexible tape is made from high-purity graphite with no fibers or binders that could contaminate your process line. Graphite is self-lubricating, plus it provides outstanding performance over a wide temperature range.

Adhesive Backing—Adhesive-back tape stays in place during installation.
