John Guest fittings make it possible to join tubes and components with a push-fit connection. The range can be selected by measurement system or by function, making it easier for you to find a fitting that matches the outside diameter of the tube and the other parts of the installation.

Choose by goal or function

Do not mix metric and imperial sizes, even if the measurements look almost identical. Always check the hose's outside diameter, thread type, material, fluid, temperature and working pressure before installation.

The hose must be cut straight and pushed all the way into the fitting. Only use the fitting in direct contact with wort or beer if the material and specifications of the specific model are stated as suitable for this.
