Nitrile (NBR) Sheet Gaskets

Nitrile (Buna-N) gasket sheets deliver reliable sealing performance in demanding applications where resistance to oils, fuels, and hydrocarbons is essential. Engineered from durable nitrile rubber compounds, these sheets combine excellent tensile strength, elongation, and abrasion resistance with consistent temperature stability, making them ideal for die-cut gaskets and custom fabricated parts. Available in a wide range of thicknesses and durometers, nitrile gasket sheets are trusted across industries such as oil & gas, chemical processing, and food & beverage equipment when compounded to FDA standards.

Frequently Asked Questions: Nitrile Gasket Sheets

What temperature range can nitrile gasket sheets handle?

Standard nitrile sheets typically perform between –30 °F and +220 °F (–34 °C to +104 °C), with specialty grades available for extended ranges. Always confirm the compound rating before final selection.

Are nitrile gasket sheets resistant to chemicals?

Yes. Nitrile offers excellent resistance to petroleum-based oils, diesel, gasoline, and many solvents. However, it is not recommended for strong oxidizing agents, chlorinated hydrocarbons, or highly polar solvents like ketones.

What durometer options are available?

Nitrile gasket sheets are manufactured in a wide range of hardness values, typically 40 to 90 Shore A, allowing engineers to match the right balance of flexibility, compression, and durability for their sealing application.

Can nitrile gasket sheets be used in food and beverage applications?

Yes. When compounded with FDA-approved ingredients or certified to 3-A Sanitary standards, white or specialty nitrile sheets can be safely used for gaskets in food, beverage, and pharmaceutical equipment.

How do nitrile gasket sheets compare to neoprene or EPDM?

Compared to neoprene or EPDM, nitrile provides superior oil and fuel resistance. Neoprene offers better weathering properties, while EPDM is preferred for hot water, steam, and outdoor ozone exposure. Material selection depends on the environment and media being sealed.

What sizes and thicknesses are available?

Nitrile gasket sheets are offered in common roll widths of 36", 48", and 72", with thicknesses ranging from 1/32" up to 2". Custom widths, lengths, and cut gaskets are also available to meet application needs.
