Chesterton 1400R 2.11lb 0.312″ Graphite Tape Packing Spool 001054

Chesterton 1400R Carbon-Reinforced Graphite Packing

The Chesterton 1400R is a premium carbon-reinforced graphite packing designed for high-temperature and high-pressure applications. This 2.11 lb spool features a 0.312″ (5/16″) cross-section, making it suitable for a variety of industrial sealing needs.

Key Features

• Reinforced Construction: Incorporates carbon yarn reinforcement within both the graphite tape yarn and the braided structure, enhancing strength and durability.
• Corrosion Inhibitor: Contains a passive molybdate-based corrosion inhibitor to protect equipment components.
• Homogeneous Sealing: Forms a uniform mass under gland pressure, effectively preventing leakage through the packing set.
• High Performance: Withstands elevated shaft speeds while minimizing friction, and the structural carbon fiber reinforcement prevents extrusion in high-pressure valve applications.

Applications

The 1400R packing is versatile and suitable for use in both rotating equipment and valves, making it a universal mechanical packing solution. Common applications include:

• Agitators
• Boiler feed pumps
• Condensate pumps
• Pulpers
• Stock pumps
• Refiners
• Mixers
