3300M Mica Valve Packing

The 3300M Mica Valve Packing is engineered for sealing applications where temperatures exceed the limits of traditional flexible graphite packing. Designed for extreme heat environments, it delivers reliable performance in demanding industrial services, including power generation, refining, chemical processing, and other high-temperature applications.

Description

  • Standard Material: Braided compression packing consisting of mica yarns jacketed with nickel alloy 625 or Inconel® wire to prevent extrusion
  • Applications: High-temperature sealing for industrial valves, exhaust systems, furnace doors, and gas and oil burners across power, nuclear, refining, chemical, and pulp and paper industries
  • Available Sizes: 1/8” to 1” (3 mm to 25 mm) Cross Sections – Larger sizes available upon request
  • Pressure Limit: Application dependent – Consult engineering
  • Temp Limit: 1,832°F (1,000°C)
  • Chemical Resistance: pH (0-14)

Key Benefits

  • Ultra High Temperature Braided Packing
  • Perfect for molten salt applications, engine exhaust systems, & stem packing applications where temperatures exceed flexible graphite packing capabilities
  • Can be used as an oxidation barrier in graphite packing sets
  • Compatible with solvents, acids, bases and mineral oils
