multiFlon® Tape

Multidirectional expanded PTFE gasket from the spool

multidirectional ePTFE gasket tape for metallic and glass lined flanges, TA-Luft certified – FDA compliant

multiFlon® Tape is the high-quality seal for reducing maintenance and material costs for large pipelines and metallic or enamelled apparatus flanges!

multiFlon® Tape is a multidirectional ePTFE gasket tape made from 100% pure PTFE.

After simple, application-specific installation, the result is a high-quality and efficient seal whose properties are directly comparable with a seal made of sheet material.
The multi-directional ePTFE gives the material excellent creep resistance to ensure a permanently tight and blow-out proof seal.

multiFlon® ePTFE gasket tapes are self-adhesive on one side, flexible and extremely adaptable.

multiFlon® gasket tapes in the “GMP” version are available for demanding applications with high purity requirements.

Typical applications
  • Components
    Agitators, columns, pumps, housings, all large flange connections, also with higher unevenness, boilers (for TRD401 use the gasket specially approved for this purpose) as well as heat exchangers in various industrial sectors.
