Nitrile Rubber Gaskets

NBR stands for Nitrile Butadiene Rubber, the base polymer of nitrile gaskets. In the context of sanitary process components, NBR is frequently referred to as BUNA-N. These gaskets are prized for their chemical resistance, wide temperature range, and compliance with sanitary standards such as FDA 21CFR177.2600, USDA, and 3-A Sanitary Standards.

Artesian Systems' BUNA-N tri-clamp screen gaskets are available in two filtration ratings: 20 micron and 100 micron. The 20 micron option provides finer particle filtration for more demanding pharmaceutical or biotech processes, while the 100 micron option suits general sanitary filtration in food, beverage, and chemical applications.

Both the 20 micron and 100 micron BUNA-N tri-clamp screen gaskets are available in six standard sizes: 1.5", 2", 2.5", 3", 4", and 6". These sizes are designed to fit standard tri-clamp fittings commonly used in sanitary piping systems across food, pharmaceutical, and industrial processing environments.

Yes. Artesian Systems' BUNA-N nitrile rubber gaskets comply with FDA 21CFR177.2600 and FDA 21CFR177.1550, are USDA approved, and meet 3-A Sanitary Standards. They have also passed U.S.P. Class VI Cytotoxicity testing, making them suitable for use in food and beverage, pharmaceutical, biotech, and other regulated processing environments.

Artesian Systems' BUNA-N (nitrile rubber) gaskets are rated for use across a wide temperature range of -40°F to +250°F (-40°C to +121°C). This broad range makes them suitable for both cold-chain food processing and elevated-temperature sanitary process applications in pharmaceutical and chemical industries.

BUNA-N nitrile rubber gaskets are compatible with petroleum derivatives, alcohols, ethers, glycols, fats, oils, greases, and natural or slightly acidic salt solutions. They are not recommended for use with strong acids, ketones, esters, or aromatic hydrocarbons. Always verify chemical compatibility for your specific process before installation.
