Uses
The use of the screw-together pipe fittings makes installing the multi-layer pipe easy, and moreover it requires very few tools.
The 24×19 threading allows for a single type of fitting which can be matched with Emmeti seals 24×19 for multi-layer pipe (see section nr. 6 – Connection and Control of Heating Units), thus rationalizing stocks. The hydraulic seal is ensured by means of a system with three O-rings and a toothed pipeholding ogive.
All the fittings are equipped with a special PTFE ring that insulates the aluminium of the pipe from the brass fitting.
Construction
The single body seal is supplied with it components (nut, olive, adaptor) already assembled and ready for insertion into the pipe.
The opening on the nut makes it possible to verify if the fitting has been inserted all the way down to the Seat point.
