ML 4460 Car-Graf Packing

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.

ML 4461 Carlon Packing

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.
