Compression union for PE pipe Ø20 mm x 1/2" male thread

Straight compression union for polyethylene (PE) pipe with a 20 mm outside diameter, with a 1/2" male thread on the other side. The pipe goes into the nut and is held and sealed as the nut is tightened, with no glue or welding. This is the usual type of joint on water and irrigation networks with PE pipe.

Use it to go from PE pipe to a 1/2" female thread, for example on a valve or manifold. Check the pipe outside diameter: these fittings are for 20 mm pipe.
