Spectrum 6375 O-ring seals, which
were fitted into thermo forming
moulds producing components used
in industrial process automation,
have operated for six years at
production steam temperatures up to
165°C without failure. This period of
uninterrupted production has been
calculated to represent a cost saving
of nearly 140K Euro over the
manufacturing period 2005-2010.

These cost savings result from
reductions in down-time, with
increased production reliability of the
14 large thermo forming moulds
which represent the manufacturers’
key compression moulding process.

Prior to the fitment of the Dupont
Kalrez Spectrum 6375 seals, the
moulding manufacturer needed to
replace the original O-rings roughly
every six months.
