Hose connection

An 8/6 mm threaded hose connection is supplied for the hose connection as standard. The switchgear can be
supplied with other threaded hose connections as an option.
A retrospective replacement of the threaded hose connection is also possible. The threaded hose connection
must have a G1/8" internal thread with the device. When replacing the connection, it is important to hold the
relevant nut in place with a 14 mm spanner. The screw connection must be used with a suitable sealant in all
cases.
