  3. Image of SEPCO 2250 valve packing

    Starting at: $46.95

    Construction: Plait Braid
    Features: Yarns are coated in PTFE suspensoid. This system of impregnation assures even distribution of the PTFE. The fibers are saturated and sealed with the PTFE particles, protecting the fibers from chemical action.
    Surface Treatment: A surface coating of PTFE is applied after braiding. No oil or lubricant is added.
    Equipment: Valves, flanges, expansion joints.
    Recommended For: Valve service and static gasket applications, caustics and mild acids.
    Service Conditions: Temperatures to 500°F/260°C; pH 3-11.
    Remarks: Use wherever break-in oil is undesirable.
    SEPCO ML2250 packing is the same as SEPCO 2250 packing except multi-lok braided.

  6. Image of SEPCO ML2001CC graphite yarn braided packing with carbon corners

    Starting at: $68.49

    Construction: Multi-Lok Braid
    Features: Pure homogenous graphite bonded to a fiberglass carrier for strength and thermal stability. It has no added lubricants or binders to cook out or become brittle. The carbon corners make the packing even tougher and helps minimize packing extrusion.
    Treatment: None.
    Equipment: The carbon corners allow the packing to be used on worn equipment where packing extrusion could otherwise be a problem. Pumps and valves, volatile organic chemical service.
    Recommended For: Rotating shafts where high shaft speeds and thermal conductivity are required.
    Service Conditions: Shaft speeds to 4000 FPM; temperatures to 850°F/454°C in oxidizing conditions; 1200°F/649°C in steam; pH range 0-14 except strong oxidizers.
