Chesterton’s Style 1400R combines twisted graphite tape with a carbon reinforcement yarn to create a flexible braided graphite spool packing with increased extrusion resistance and higher pressure capability.
Superior Leakage Control
Typical braided packings, including graphite types, present possible leak paths between the braids. In contrast, 1400R forms a homongeneous mass under gland pressure, so that leakage cannot penetrate the set.
Improved extrusion resistance
1400R’s unique construction increases extrusion resistance, eliminates the need for separate anti-extrusion rings*. Increased extrusion resistance also increases the maximum pressure rating without end rings.
Ideal applications include, steam valves, agitators, boiler feed pumps, condensate pumps, pulpers, stock pumps, refiners, mixers, etc.
*When attempting to reduce or eliminate flush water from a stuffing box, Chesterton’s 477-1T packing can be used as a non-contaminating carbon yarn anti-extrusion end ring.
