Note for use of compression fittings
When using compression fitting, the thread of
the fitting and the compression ring are slightly
oiled at works. Do not use any additional
lubricant! Do not allow the oil or lubricant to
come into contact with the EPDM valve disc.
EPDM is not oil resistant.
Only use original Oventrop compression fittings.
It is important that the pipes are cut to the
correct length at a right angle to the centre
line. The ends of the pipe must be free of burrs
and undamaged.
When using thin walled and very soft pipes,
reinforcing sleeves have to be used. The
reinforcing sleeve supports the pipe and provides
the strength to enable the necessary
compression. Reinforcing sleeves cannot be
used on pipe with welded seams. The
recommendations of the pipe manufacturers
must always be observed. If necessary, a
practical test has to be carried out.
The special fittings "Cofit S" may be used for
the Oventrop composition pipe "Copipe". The
installation instructions supplied with the fittings
must be observed.
