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.

What is Duramax Ultra-X High-Performance Packing? 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.
Benefits of Ultra-X High Performance Packing
Stays pliable-will not harden or become brittle Easy to install and remove for repacking Grease-free installation - east to cut, and conforms easily High tensile strength - not consumed in use Self-lubricating - virtually needs no water to lubricate Virtually eliminates maintenance, shaft scoring and replacement
Duramax Ultra-X always runs cool, even at high shaft speeds. Ultra-X transfers frictional heat to stuffing box, which functions as a heat sink. In contrast, flax packing acts as an insulator, trapping frictional heat that can cause shaft damage and loss of seal.
