Construction: Multi-Lok Braid
Features: The highest quality chemically resistant graphite yarns are twisted together and braided in a Multi-Lok fashion. This packing has an extremely low coefficient of friction. The light weight yarn provides more feet of length per pound than standard non-asbestos or PTFE packings. Graphite is a heat conductor and dissipated heat in the stuffing box, permitting higher shaft speeds and less leakage than other packings.
Equipment: All rotating and reciprocating shafts, valves and agitators. Our best packing for top separators and outlet devices on continuous pulp digesters.
Recommended For: Strong caustics, acids, chemicals and high pressure steam.
Limitations: Temperatures to 1200°F/649°C in steam, 800°F/427°C in oxidizing atmospheres; pH range 0 - 14; not recommended for fuming nitric acid, oleum and fluorine.

Construction: Multi-Lok Braid
Features: Manufactures from pure graphite yarns impregnated with a fine submicron powder of inorganic graphite. A surface lubricant is applied to prevent wicking and to provide a bearing film between the shaft and the packing material.
Equipment: *Valves, high speed shafts, agitator shafts, reciprocating rods and plunger rods wherever minimum product leakage is required under severe service conditions.
Recommended For: Strong acids and strong caustics throughout the pH range. It is virtually inert.
Limitations: Not recommended for oleum, fuming nitric acid and flourine; temperatures to 6000°F/3316°C in non-oxidizing agents, 1200°F/649°C in steam, and 800°F/427°C in oxidizers.
Can Be Nuclear Certified.

*End rings only in conjunction with flexible graphite rings when used in valve packing applications.
