Duramax Ultra-X lasts over 5 times longer than other packing.
Ultra-X is a high performance, non-asbestos, compression packing that is engineered specifically for the marine industry. Its excellent lubricity and high thermal conductivity keeps shafts running cool at all speeds. Unlike flax and other packing materials, once Ultra-X is installed you never need to worry about it again, virtually eliminating maintenance.
It is a braided hydrophobic fiber packing. A unique, patented manufacturing technology encapsulates graphic particles and impregnates specialized lubricants into its expanded PTFE strands. Unlike competitors’ packing that blends graphite particles between strands during the braiding process.
