Important note: Dichtomatik products comply with common industrial standards and therefore are suitable for many applications excluding safety-critical ones like Automotive. Premium Freudenberg products are the right choice for all applications ensuring highest quality and safety standards and therefore optimal total cost of ownership.

Product Characteristics

Flange gaskets of the Dichtomatik brand are available in thermoplastic polyurethane (TPU) with an operating temperature of -30 to +100 °C and up to a pressure of 60 MPa. They are resistant to hydraulic oils to DIN 51524 Parts 1-3, H, HL, HLP and flame-retardant hydraulic fluids (HFA, HFB, HFC) as well as lubricating oils, mineral oil-based lubricating greases, silicone oils and greases and water up to +60 °C as well as aliphatic hydrocarbons.

Other types like FLA flange seals are available on request (offers may vary per region).

Please note that resistances, pressures and temperatures are mutually influenced by various parameters.
