  • John Guest® BPEX 12mm Tubing

    The John Guest® 12mm BPEX White Pipe has been specifically designed to meet Australian Standards to be compliant with WaterMark. The benefits of this product is its increased maximum working temperature and pressure compared to the standard LLDPE tubing. JG® BPEX tubing is warranted to achieve 80°C at 1000 kPa

    Manufactured in the UK by John Guest, the BPEX pipe is made of 5 layers, the centre of which is a blue coloured oxygen barrier which prevents the ingress of air into the system, reducing the effect of corrosion on metal components. Due to its low thermal conductivity, when carrying hot water, the BPEX pipe is cooler and safer to touch.

    When using BPEX pipe on hot water, tubing inserts must be used (TSM12 - GT10-131WM)

  • Please note that this tubing is only available in WHITE

    Making a Good Connection

    Prepare the Pipe:

    Ensure the pipe end is free from score marks. Cut the pipe square using a tube cutting device. To prevent damage to the fitting, remove and burs from the end of the tubing/pipe. When using tube inserts, a twisting motion will aid the insertion.

    Twist & Lock™:

    The fitting should be in the unlocked position, this is shown by a small gap between the screw cap and the body flange. Push the pipe fully into the fitting until it hits the pipe stop. When the piping has been securely inserted, screw the twist lock cap into the locked position. Give a firm pull to the pipe to check that it is secure. It is good practice to test the system prior to leaving site or before use.

    To Disconnect:

    The screw caps will need to be screwed back to an unlocked position. Push the collet square against the face of the fitting by using fingers or a collet release tool. With the collet held in this position, the pipe can be removed. The fitting can be used multiple times without replacement.

    What NOT to do

    Do not use hacksaws or any other tool that created burs or rough edges on the pipe, don’t use damaged or scored pipe as this can damage the O-ring.

    Don’t forget to push the pipe fully into the fitting, past both the collet (teeth) and the internal O-ring.

    Do not insert finger into the fitting as the stainless-steel teeth may cause injury. Always test the system under pressure to check for leaks.
