Selecting the best gasket material for a specific application depends on various factors, including the type of fluid or gas being sealed, temperature and pressure conditions, and the compatibility with the mating flanges or surfaces.
Here are some common gasket materials and their typical applications.
Compressed Non-Asbestos (CNA): Suitable for general-purpose applications with water, oil, and mild chemicals at moderate temperatures and pressures.
Expanded PTFE (ePTFE): Ideal for sealing applications involving aggressive chemicals, high purity processes, and cryogenic conditions.
Viton/FKM: FKM rubber is primarily used in applications where resistance to aggressive chemicals, high temperatures, and environmental extremes is essential.
Neoprene: Resistant to oils, ozone, and weathering; commonly used in HVAC systems and outdoor applications.
Nitrile (NBR): Suitable for sealing oils, fuels, and hydraulic fluids.
EPDM: Excellent resistance to weathering, UV, and ozone; used in outdoor applications and as a seal for water and steam.
Flexible Graphite: Effective for high-temperature and high-pressure applications, including steam, hydrocarbons, and acids.
Spiral Wound: Often used in high-pressure and high-temperature applications with various fluids, including corrosive ones.
Ring Joint: Commonly used in high-pressure applications, such as oil and gas pipelines.
Metal Jacketed: Suitable for sealing heat exchangers and other equipment in high-temperature and high-pressure environments.
Virgin PTFE: Resistant to a wide range of chemicals and temperatures; used in various industries for sealing applications.
Filled PTFE (e.g., glass-filled or carbon-filled): Enhanced strength and performance, especially in applications involving aggressive chemicals.
Cork-Rubber: Used in low-pressure applications and where vibration damping is required, such as automotive gaskets.
Cellulose Fiber: Suitable for low-pressure, non-corrosive applications, such as water and oil.
Silicone Rubber: Resistant to extreme temperatures and UV exposure; commonly used in food-grade and medical applications.
Non-metallic Fiber Material: Suitable for low-pressure, non-corrosive applications, such as transformer gaskets.
Compressed Sheet Gaskets
Graphite with a Metal Core: Excellent for high-temperature and high-pressure applications.
