Description
Our sanitary gaskets are available in a variety of materials and styles, each possessing unique performance characteristics, and should be selected based on the specific demands of the application.
Please refer to the sanitary gasket elastomer characteristics to assist with proper gasket selection.
For a specific chemical resistance see our compound selection chart.
All gaskets are manufactured to meet both FDA and 3A sanitary standards.
Buna (Nitrile) gaskets are the most popular and economic and are common in food and beverage applications. They have good resistance to oils and animal fats, and good resistance to moderately aggressive chemicals.
PTFE (Teflon®) gaskets exhibit exceptional chemical resistance, and extremely high tolerances to heat and steam.
However, they’re a plastic as opposed to an elastomer, and therefore not as compressible as other gasket materials, which can lead to difficulty in sealing if misaligned.
They can experience cold flow, especially if clamps are misaligned or overtightened, resulting in a reduction in sealing pressure.
