Moulded Fittings and Pipe
Johndec moulded fittings are seamless moulded and are segment free, the fittings can contain both gaseous, abrasive and corrosive media. The Johndec moulded fittings are offered at the standard tube nominal diameters and can be manufactured with pipe connections; bushing connection and flanged connections. Standard extruded pipe is also available to suit the fittings.
The Johndec-moulded fittings are suitable for assembling in pipelines in which gaseous, abrasive and corrosive media are transported. As materials for the Johndec-moulded fittings, different thermo-plastics stand with different and maximally permissible thermal loads for the selection.

Increasing temperatures deoxidise the permissible system compression. Please, hold consultation at other temperature ranges with the manufacturer.
