MDPE Male Threaded Tee 20mm to 32mm

The MDPE Male Threaded Tee sits in a run of blue MDPE water pipe and gives a male BSP thread on the branch, sold in 20mm x 1/2″, 25mm x 3/4″ and 32mm x 1″ for plumbers and groundworkers feeding taps, troughs or outbuildings off a supply. Both run ends are compression joints for MDPE.

Cut the pipe, fit the tee, and the branch is ready to go into a female fitting such as a valve, a hose union or an adaptor to another pipe type. It is a common choice on garden, farm and temporary site supplies.

Pick the size to match the main pipe, not the branch. Fit liners in both run ends, seal the branch thread with PTFE tape or paste, and hold the tee steady as you tighten the fitting onto the branch so you don’t twist the run. Female versions, couplings and stop valves are in our MDPE male threaded tee section.

Common Questions

Male or female branch, which do I need? Look at what goes on the branch. A valve or fitting with a female thread needs the MDPE Male Threaded Tee, and anything with a male thread needs the female version.

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.

How deep should MDPE water pipe be buried? The water regulations ask for at least 750mm of cover and no more than 1350mm. That keeps the pipe below frost and still reachable if it ever needs dug up.

Does the thread need sealing? Yes. Wrap PTFE tape the same way as the thread, or use a jointing paste approved for drinking water, on the male branch before the next fitting goes on.
