MDPE Female Bend 20mm to 32mm

An MDPE Female Bend turns blue MDPE cold water pipe through 90 degrees and finishes in a female BSP thread. We sell 20mm x 1/2 inch, 25mm x 3/4 inch and 32mm x 1 inch for plumbers and groundworkers bringing an underground supply up to a valve or tap.

Use it where an underground supply comes up into a building, a standpipe, a trough or an outside tap, and you need to screw on a valve or male fitting. The first size is the MDPE pipe’s outside diameter and the second is the female thread: 20mm x 1/2 inch is the common domestic service size, 25mm x 3/4 inch suits bigger domestic supplies and long runs, and 32mm x 1 inch covers farm, yard and small commercial feeds.

Cut the pipe square with proper cutters, not a saw, and fit a pipe insert in the end so it doesn’t collapse under the compression ring. Slide on the nut and ring the right way round, push the pipe fully home and tighten. Seal the male thread going into the MDPE Female Bend with PTFE tape and don’t overtighten into plastic. Insulate the riser where it comes out of the ground. Inserts and the rest of the range are in our MDPE female bends section.

Common Questions

Is 25mm MDPE 25mm inside? No. MDPE is sized by its outside diameter, so 25mm pipe measures 25mm across the outside and the bore is smaller. Measure the outside to pick the right fitting.

Do I need a pipe insert? Yes. An insert stops the pipe squashing under the compression ring and gives a firm joint. Push it fully into the pipe end before fitting.

How deep should MDPE be buried? The usual guidance for a water supply is at least 750mm of cover and no more than 1350mm, to keep it clear of frost. Where it rises out of the ground, insulate it.

How do I seal the thread? Wrap PTFE tape on the male fitting going into the MDPE Female Bend. Tighten firmly but don’t force it, as plastic threads crack.
