6 Tri Clamp BUNA Screen Gasket — 841 Micron FDA

841 micron refers to the mesh opening size of the stainless steel screen insert. Particles larger than 841 microns are captured by the screen while fluid passes through. This coarser rating is suited for applications requiring protection against larger debris without significantly restricting flow rates in sanitary pipeline systems.

Yes. BUNA-N nitrile used in these screen gaskets complies with FDA 21CFR177.2600 and FDA 21CFR177.1550, is approved by 3-A Sanitary Standards, USDA approved, and has passed U.S.P. Class VI Cytotoxicity testing — making it suitable for food, beverage, pharmaceutical, and biotech fluid handling applications.

The BUNA-N Tri Clamp screen gaskets are available in six standard sizes: 1.5", 2", 2.5", 3", 4", and 6". These cover the most common Tri Clamp fitting dimensions used across sanitary processing systems in food, dairy, pharmaceutical, and chemical industries.

These BUNA-N Tri Clamp screen gaskets are rated for an operating temperature range of -40°F to +250°F. This wide range makes them suitable for both cold processing environments, such as refrigerated food lines, and elevated-temperature applications including pasteurization and hot chemical processing systems.

BUNA-N (Nitrile) is compatible with petroleum derivatives, alcohols, ethers, glycols, fats, oils, greases, and natural or slightly acidic salt solutions. It is not recommended for use with strong acids, ketones, or chlorinated hydrocarbons. Always verify compatibility with your specific process fluid before installation.

The 20 micron gasket provides finer filtration, capturing smaller particles and is ideal for pharmaceutical, biotech, and precision food processing applications. The 100 micron version offers coarser filtration with less flow restriction, suited for general sanitary filtration in food, beverage, and chemical processing lines where larger particulate removal is the primary goal.
