Assembly of the entire SERTO range is very simple. Insert the tube or the hose into the union, which is supplied ready for assembly, tighten by approx. 1 3/4 turns - finished. This applies for all materials and dimensions. The only exception is the SERTO Selection orbital welded connection - here approx. 1/8 turn is sufficient. You only need a standard spanner; you do not need special devices or test gauges. Thanks to this simple assembly, the unions are always leak-proof.
However, there are product-specific features that need to be observed during assembly and we always recommend that you follow the relevant installation instructions.
