Reinforced anti-extrusion graphite packing for high-pressure applications

The performance of expanded graphite combined with the benefits of braided packing.

Advantages
  • Packing for high-temperature steam and aggressive chemical sealing
  • Industrial valve applications
  • Anti-extrusion packing for high-pressure services

Detailed Description

Braided packing made from expanded graphite yarns reinforced with Inconel wires and coated with a graphite blend. LATTYgraf 6940 contains a corrosion inhibitor to protect both the stem and the stuffing box. Its unique construction withstands high pressures without the risk of graphite extrusion. Designed for high-performance and high-temperature applications, particularly in petrochemical industries when used in combination with LATTYgraf E. Use with caution in oxidizing environments. Available on request as die-formed rings. Composition: carbon-graphite.

The maximum temperature, pressure and speed given cannot be associated in any case. Weights, given for information purposes, are not contractual.
Unless otherwise requested and explained and validated by our technical services, all our stamped rings are manufactured according to our manufacturing standards.
