Construction: Braided inconel wire-inserted carbon yarn over mastic core.
Features: Inconel wire-inserted carbon yarn jacket over a core of high temperature fibers and graphite. A corrosion inhibitor is added to protect the valve.
Surface Treatment: Molycoated.
Recommended For: Steam, super-heated steam, air petroleum products, hot gasses.
Limitations: Recommended for valve service; maximum line temperature 1200°F/649°C, pressure to 2500 p.s.i.

Construction: Multi-Lok Braid
Features: Car-Graf is an unique combination of amorphous carbon yarns treated throughout with fine particles of graphite.
Treatment: Treated throughout with graphite.
Equipment: General service on rotary and reciprocating shafts, high temperature valves as end rings.
Recommended For: All chemical services in which carbon is suitable.
Limitations: Shaft speeds to 4000 FPM; temperatures to 650°F/345°C in oxidizing atmospheres; 1200°F/650°C in steam; pH range 0 - 14 except in strong oxidizers.

Construction: Multi-Lok Braid
Features: SEPCO ML 4461 Carlon is a carbon filament packing treated with PTFE to help prevent color contamination and carbon migration.
Treatment: Each strand of the carbon yarn is treated and impregnated with a PTFE suspensoid, totally encapsulating the packing to prevent carbon filaments migrating into the pumpage.
Equipment: Pulp mill equipment, steaming vessels, top separators, refiners, outlet devices, blow pumps, stock pumps, agitators and valves.
Recommended For: Most chemical services, except strong oxidizers.
Limitations: Shaft speeds to 3000 FPM; temperatures to 600°F/345°C; pH range 0 - 14.
