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.
