Pump and Valve Packings

1400R

Chesterton 1400R is a unique reinforced braided graphite tape packing with a corrosion inhibitor, The carbon yarn reinforcement is provided within the graphite tape yarn, as well as the braided construction. 1400R forms a homogeneous mass under gland pressure, so that leakage cannot penetrate the packing set. The all carbon/graphite set withstands higher shaft speeds while limiting shaft friction.The structural carbon fiber reinforcement prevents extrusion when 1400R sets are installed in valves at higher pressures. In addition to its excellent sealing capabilities in rotating equipment, 1400R is a superior valve sealing material. This dual purpose design makes it a truly universal mechanical packing.

477-1

Chesterton 477-1 carbon fiber packing combines a new yarn formulation with superior blocking agents.New low modulus yarn provides the strength associated with continuous filament carbon fibers plus greater flexibility. This makes 477-1 strong yet pliable, without the brittleness of conventional carbon packings. 477-1 incorporates a high purity dispersion of inorganic platelets which prevent penetration of gases or liquids through the packing. Interbraid construction locks these blocking agents within the packing ring.

1400

Chesterton 1400 is a pump and valve packing constructed from graphite tape which is twisted, braided and treated with corrosion inhibitors and a blocking agent. 1400 forms a homogenous mass under gland pressure for maximum sealability.
