MDPE Fittings & Pipe

Blue MDPE outdoor / underground "poly" mains water pipe and fittings.

Picture showing how MDPE pipe is measured

MDPE pipe is measured by its outside diameter. MDPE stands for "Medium Density Polyethylene", if you were wondering.

We do not stock the old black plastic Alkathene mains water pipe or fittings any more, but we do have a page with information about its sizes.
