FDA Compliant Buna-N Gaskets — Temperature Range

The maximum continuous service temperature for Buna-N (Nitrile) is +250°F (+121°C). Exceeding this threshold can cause the elastomer to harden, crack, or lose its sealing integrity. For higher-temperature applications, alternative gasket materials such as EPDM or PTFE should be considered.

Yes. Artesian Systems' Buna-N gaskets comply with FDA 21CFR177.2600 and FDA 21CFR177.1550, which govern rubber articles and polymeric components intended for food-contact applications. They are also 3-A Sanitary Standards approved, USDA approved, and have passed U.S.P. Class VI Cytotoxicity testing.

Artesian Systems offers FDA-compliant Buna-N Tri Clamp screen gaskets in two filtration ratings: 20 micron and 100 micron. The 20 micron version provides finer particle capture for pharmaceutical and biotech lines, while the 100 micron version suits broader sanitary filtration in food and beverage processing.

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 dimensions are compatible with standard Tri Clamp sanitary fittings used across food, pharmaceutical, and chemical processing piping systems.

Buna-N gaskets are compatible with petroleum derivatives, alcohols, ethers, glycols, fats, oils, greases, and natural or slightly acidic salt solutions. They are not recommended for strong acids, ketones, or chlorinated solvents. This broad chemical compatibility makes them well-suited for food processing, dairy, brewing, and petroleum transfer applications.

The screen insert is constructed from 316L Stainless Steel, chosen for its superior corrosion resistance, sanitary surface finish, and durability in aggressive process environments. 316L is the industry standard alloy for food-grade, pharmaceutical-grade, and chemical-grade inline filtration applications due to its low carbon content and resistance to chloride attack.
