PTFE packing type EPB

The packing braided of delicate yarn of pure PTFE in fibres without supplement of silicon oil, which enables the application in contact with food and drinking water, where impregnants on the basis of silicon are unacceptable. Is characterized by unsurpassed flexibility, which facilitates adjustment to the sealed elements. High chemical resistance, even to very aggressive utilities, is the most important asset of this packing.

Application

Recommended for use in rotational pumps, piston pumps and in industrial fittings, in the food, chemical and pharmaceutical industry and in drinking water treatment stations. Resistant to the impact of water, steam, oils, fuels, solvents, acids and alkali apart from strong oxidants. The packing has the attestation of PZH.
