The choice of rubber material for use in sealings and hoses in the fuel system is of
great importance. If a wrong type of rubber is used, premature failure during service
may occur. This impacts the environmental performance, the safety during driving,
uptime and economy of the transport. In this diploma work, rubbers for use in sealing
and hoses in the fuel system have been evaluated to assess which materials have the
potential to be used under long-term use in contact with commercial fuels.
