Lightweight construction is the new focus of engine development



For more than a century, the internal combustion engine took care of most of our mobility needs. Innovative products from Freudenberg Sealing Technologies are helping to unlock the ultimate efficiency potential of this traditional engine technology. Downsizing and lightweight construction combine high performance with low fuel consumption and reduced emissions. Minimized installation spaces and increased pressure and temperature requirements turn seals into high-tech components. Freudenberg Sealing Technologies is ready for the challenge.


90% less friction + longer service life = Levitex

The gas-lubricated Levitex mechanical seal approaches the vision of a frictionless seal. 90 percent fewer friction losses than a conventional crankshaft seal. As a result, the CO2 emissions during vehicle operation decline to as low as one gram per kilometer. Less wear leads to a longer service life. In addition, the high pressure stability of Levitex also blazes a completely new trail in engine development.

LESS includes sustainable sealing technology solutions of the future for all vehicle components.

New media – New requirements – New solutions



Emissions don’t originate in the exhaust alone. Gasoline permeation out of fuel hoses is a frequently underestimated topic. With FluoroXprene, we have a fluorinated thermoplastic elastomer that is used for the fuel hose’s middle shell and is characterized by more than just flexibility and flexural strength. It also effectively prevents gasoline fumes from escaping into the atmosphere.
Magnet-anchor solutions

Magnet-anchor solutions

Tank ventilation systems offer many application possibilities for our customer- specific magnet-anchor solutions, such as tank cutoff valves, air isolation valves, or regeneration valves. They’re designed for a temperature range from −40 °C to 120 °C and are characterized by a high degree of media stability relative to fuel and aggressive blow-by gases.
