Material:

Black acetal resin (POM), elastomer O-rings (NBR or EPDM).

How to use it:

  1. Cut the tube square, clean and free of cracks.
  2. Fit the valve in the direction of water flow: it only lets water through one way.
  3. Push the tube fully into the fitting with moderate force, without scratching it.
  4. Pull lightly on the tube to check that it holds.
  5. To remove it, release the pressure first, push the collet towards the fitting body and pull the tube out.

The fitting and the tube can be reused.
