1 ouplings for polyethylene pipe series cert. n 0003 ISO 9001 LFFI 01037/03 G Function couplings, which are supplied in brass for diameters up to 63 mm and in cast iron for larger sizes, are used for connecting polyethylene piping. s proof of the high standard of quality, the threaded connections (up to ) have VGW and SVGW approval, which means that they are approved for use in Germany and Switzerland.

4 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. Series 887 pipe stiffener ode from to from to from to from to from to max. 50 Series PN x x 2, x x 3, x 4, x 5,8 Strength aleffi couplings are not affected by frost, as any deformations are absorbed by the pipe itself. In addition, in the case of ground movement or excessive loads in the connection area, there is no risk of breakage or disconnection. For RHU pipes x 2, x 3,5 Preparation of the pipe 90 Instructions for the correct assembly of couplings do Insert the pipe into the coupling with the nut slackened. o not cut at an angle Remove any external burrs ut at 90 do not ismantle the coupling and slide the various components onto the pipe.
