Chesterton’s 5800T combines the excellent thermal and physical stability of graphite and the low friction properties of PTFE. The packing set incorporates the unique Chesterton WedgeSeal design with an innovative graphite/PTFE hybrid packing material.

The complete packing set uses the graphite/PTFE hybrid against the dynamic stem where friction is the concern. 5800T meets the difficult sealing requirements of both state and federal regulations for VOC emissions and in stem services.

• Designed specifically for Air Operated Control Valves
• For service temperatures below 450°F (230°C)
• Exceeds U.S.EPA requirements for emissions services (<500 ppm as measured by EPA Method 21)
• Very low friction design ensures most efficient valve operation
