MDPE Universal Transition Bend 25mm

The MDPE Universal Transition Bend joins blue MDPE water pipe to copper and turns the run through a bend in the same fitting, sold in 20mm x 15mm and 25mm x 22mm for plumbers bringing a main up out of the ground or through a floor. The first size is the MDPE and the second is the copper.

The usual spot is where the incoming main rises inside the house and changes from plastic to copper, often right at the stopcock. Doing the change of material and the change of direction together keeps things tight to the wall. The universal end grips a small range of pipe sizes and types, so check the range marked on the body suits your pipe.

Both ends are compression joints. Put a liner in the MDPE, cut both pipes square and clean off any grit before they go in. The 25mm x 22mm suits most house mains and the 20mm x 15mm suits smaller supplies and outside taps. Straight transition couplings are with our MDPE universal transition bends.

Common Questions

What does universal mean on a transition fitting? The universal end is made to grip a range of outside diameters, not one exact size. That lets the same fitting take copper and some older pipe types. The grip range is marked on the fitting.

Which size do I need for a house main? Most mains come in as 25mm MDPE and change to 22mm copper, so the 25mm x 22mm is the usual one. Smaller or older supplies often run 20mm MDPE to 15mm copper.

Do I need a pipe liner in the MDPE? Most makers of MDPE compression fittings ask for a liner in the pipe end, and it is good practice either way. The liner keeps the pipe round under the nut so the joint grips and doesn’t creep. Check the leaflet in the bag for the size of liner to use.

Bend or straight coupling? Use the MDPE Universal Transition Bend where the pipe comes up and turns in one spot. Where the change of material is in a straight line, the straight coupling is neater.
