What are common types of materials for gasket?

Industrial gasket materials are selected based on operating conditions such as temperature, pressure, and chemical compatibility. Common categories include:

Flexible Graphite Gaskets: Excellent for high-temperature and high-pressure applications. Resistant to thermal cycling and widely used in hydrocarbon and steam systems.

PTFE and Expanded PTFE (ePTFE) Gaskets: Provide superior chemical resistance, making them ideal for corrosive media such as acids, solvents, and chlorides.

Spiral Wound Gaskets (Graphite + Metal Strip) : Designed for high-pressure flange connections, combining resilience of metal with sealing ability of soft fillers like graphite or PTFE.

Metal Jacketed or Solid Metal Gaskets: Used in extreme pressure and temperature environments where mechanical strength is critical.

Each gasket type is engineered to meet different sealing requirements, and proper selection ensures both safety and long-term reliability.
