How to Install Press Fittings Safely

Press fittings are installed using a press tool, which securely crimps the fitting onto the pipe to create a leak-proof connection. Different fittings may require different press jaws, so it’s important to use the correct size and type for each pipe and fitting.

For safe and long-lasting installations:

  • Follow the tool manufacturer’s instructions.
  • Keep the press jaws clean and properly lubricated.
  • Check the fittings and tool regularly for wear.
  • Do not mix different types of press profiles.
