onstructional details ase of use series polyethylene pipe couplings are extremely practical, as they do not have to be taken apart when connecting to the piping (see example at foot of page). ccessories Series 886 reducer Repair joints Series 870 sleeve coupling allows piping connections to be made with a maximum space between ends of 50 mm. Thanks to the absence of internal ledges, the pipe can slide freely.

In addition, in the case of ground movement or excessive loads in the connection area, there is no risk of breakage or disconnection.
