​Reinforced, braided, graphite 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.​
