PVC Pipe SN4 Grey 75 x 3.0 mm. / m

A SN8 PVC pipe has a thicker wall than an SN4 PVC pipe. SN8 PVC pipes are heavy-duty and are mainly used in road construction and as a culvert pipe

The wall thickness of the PVC drain pipe influences the stiffness of the PVC pipe

The three values for the stiffness classes are SN2, SN4 and SN8, so which PVC pipe you choose depends on the external pressure exerted on the PVC pipe
