How to instantly cut threads on polypropylene and where it can come in handy

If, when soldering the pipeline, there were not enough couplings with external threads, you can cut it directly on polypropylene. This method is not suitable for a house or apartment, but if you are making an irrigation system for a garden or lawn, then the method is completely justified.

What you will need:

• soldering iron for pipes;
  
• coupling with internal thread.

Thread cutting process

The edge of the pipe needs to be heated in a soldering iron, as usual for soldering.

Then, while it is hot, a coupling with internal thread is screwed onto it.

You need to wait 5-10 seconds until the polypropylene hardens and unscrew the pipe.

This thread is not designed for high pressure, but is quite suitable for garden water supply.

That is, it is perfect for connecting with a hose connector. This method can also be used when assembling an irrigation system for a garden or vegetable garden.
