Packing Seal Tape

Plain Back

Adhesive Back

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-back tape stays in place during installation.
