The John Guest 12mm Check Valve is the perfect fitting to stop the flow of water from reversing. It features a one-way non-return valve that shuts itself when the backflow of water is detected.

This compact check valve will fit in confined spaces in your Caravan, RV or Motorhome and can be used for many other applications to stop the backflow of water.

The maximum working pressure is 1000 Kpa and the maximum temperature rating is 65 Degrees Celsius intermittently. Its ease of installation uses the same John Guest push-fit technology that is common on other John Guest Products. Locking collet clips are optional but encouraged to stop accidental disconnection of the tube and fittings.
