When selecting gasket sheets for sealing applications involving oil and fuels, it’s essential to choose materials that offer excellent resistance to petroleum-based products, including oils, fuels, and hydrocarbons. Here are some gasket sheet options commonly used for oil and fuel sealing applications:

1. Nitrile Rubber (NBR) Sheets:

   • Nitrile rubber gasket sheets, also known as Buna-N or NBR, are highly resistant to oils, fuels, and petroleum-based fluids. NBR offers excellent sealing performance and durability in applications where resistance to oil exposure is critical. Nitrile rubber sheets are commonly used in automotive, marine, and industrial equipment, including engines, pumps, and hydraulic systems.

2. Neoprene Sheets:

   • Neoprene gasket sheets offer good resistance to oils, fuels, and grease, as well as moderate resistance to weathering and ozone exposure. Neoprene is commonly used in sealing applications where resistance to oil and fuel exposure is required, such as automotive gaskets, oil pans, and fuel tanks.

3. Fluoroelastomer (FKM) Sheets:

   • Fluoroelastomer gasket sheets, such as Viton®, offer superior resistance to a wide range of oils, fuels, chemicals, and solvents. FKM materials provide excellent sealing performance and long-term durability in harsh environments, including automotive, aerospace, and petrochemical applications.

4. PTFE (Polytetrafluoroethylene) Sheets:

   • PTFE gasket sheets offer excellent chemical resistance to oils, fuels, and hydrocarbons, making them suitable for sealing applications where compatibility with aggressive fluids is required. PTFE is inert and non-reactive with most oils and fuels, ensuring reliable sealing performance in automotive, chemical processing, and oil and gas applications.

5. Non-Asbestos Fiber Sheets:

   • Non-asbestos fiber gasket sheets, particularly those reinforced with aramid fibers or synthetic elastomers, can offer good resistance to oils and fuels, depending on their composition. These gasket sheets provide reliable sealing performance in a wide range of industrial applications, including engines, compressors, and hydraulic systems.

6. Metal Sheets:

   • Metal gasket sheets made from materials such as stainless steel or aluminum can provide effective sealing in applications involving oils and fuels. Metal gaskets offer excellent resilience, stability, and resistance to compression set, making them suitable for use in engines, pumps, and fluid handling systems.

When selecting gasket sheets for oil and fuel sealing applications, it’s crucial to consider factors such as the type of fluid, operating temperature, pressure, and environmental conditions. Proper material selection and gasket design are essential to ensure reliable and long-lasting seals in oil and fuel systems.
