Duramax Ultra-X is a unique high-performance, packing specifically engineered for heavy duty marine propulsion service. It features a unique and especially even distribution of encapsulated graphite and specialized lubricants into an expanded PTFE braided matrix. Doesn't insulate like flax packing - its excellent lubricity and high thermal conductivity keep shafts running cool at all speeds.
Ultra-X stays pliable, and never hardens or becomes abrasive - even at high shaft speeds. While look-alike, black, pure PTFE products undergo thermal expansion - increasing friction and shaft scoring, Ultra-X is dimensionally stable, virtually eliminating costly damage caused by extensive shaft scoring and wear.
Outperforms flax and competitors' PTFE packings
Unlike flax packing, it is not consumed in use and is virtually maintenance-free; no need to monitor or adjust the gland
Use for stern tube, bulkhead, or rudder stuffing boxes
Self-lubricating and conformable, easy to install and remove after use
Practically dripless - doesn't shrink or swell, keeps bilge drier and free of oily contaminants
Only 1/3 the friction of flax, lasts over 5 times longer than other packing
