Flexi Underground Ducting Water - 110mm (O.D.) x 50mtr Blue Coil

Our blue underground ducting is used for ducting water supply services, usually blue MDPE pipes. It is available in coil diameters of 63mm and 110mm. These measurements refer to the outside diameters (O.D.), all dimensions can be found in the table alongside the product image.The ribbed external wall ensures that the duct can withstand high compressive forces and the ribbed inner bore resists any snagging of the water main during installation.Water supply services should be installed at a depth of between 750mm and 1350mm. This should ensure that the pipe is unaffected by either frost or potential surface digging.You should always choose a diameter that allows plenty of room within the duct to allow the water pipe to be drawn through smoothly. All full coils come with an integral coupler and a pre-installed draw cord. The coupler enables two coils to be connected together as required.The length of this coil is 50m.
