Johnson Duramax Marine Stuffing Box Packing

Ultra X Stuffing Box Packing

Ultra-X is a braided hydrophobic fiber packing.

Because of its composition and design it lasts more than 5 times longer and outperforms all flax

and PTFE packing in marine stern tube, rudder and bulkhead applications.

Available in the following sizes:
Size*	1/8"	3/16"	1/4"	5/16"	3/8"	7/16"	1/2"	9/16"	5/8"	3/4"	7/8"	1"	1 1/8"	1 3/8"	1 1/4"	1 1/2"
Approx. FT/LB	67	35	20	13	9.5	7	5	4	3.2	2.3	1.8	1.4	1.2	1	.9	.7
Standard spools of 1, 3, 5 and 10 pounds. Bulk spools of 25 and 35 pounds are also available. *Larger and custom sizes of packing is available upon request.

Expanded PTFE: Out performs standard flax and PTFE

High tensile strength: Will not get consumed in use

Graphite imbibed/silicone impregnated: Lowest friction of any marine packing

Self-lubricating: Virtually needs no water for lubrication

Stays pliable: Never gets brittle, hard or abrasive

High thermal conductivity: Over 5 times more thermally conductive than flax and PTFE

Grease-free installation: Easy to cut and handle. Conforms easily

Lowlife-cycle cost: Virtually eliminates maintenance, shaft scoring & replacement

	ULTRA X PACKING		FLAX PACKING
Ease of Installation	Pliable, conforms easily for clean, tight seal		Messy to handle, cut and install
Lubrication	Self-lubricating, virtually no water needed		Requires water
Replacement	Stays flexible and pliable, easy to remove		Dries out, gets brittle, difficult to remove
Operating Condition	Stays pliable, non-abrasive		Hardens, becomes brittle and abrasive
Resistance to Overheating	Maximum temperature 550°F		Maximum temperature 150°F
Thermal Expansion	Virtually none		Will experience swelling
Leakage	Practically eliminated		Will experience leakage
Heat Dispersion	11.9 BTU in/h ft2	°F	2.4 BTU in/h ft2	°F
Environment	No oily contaminated water in bilge, no EPA issues		Needs holding tanks or remediation
Maintenance	Once installed, needs no maintenance		Need to add rings when consumed
Equipment Damage	Virtually eliminates shaft scoring and wear		Gets hard and abrasive causing costly damage
Longevity	Normally lasts until scheduled haul out		Consumed or destroyed at high shaft speeds
