    Polypipe PB5028B Details

    Polyplumb barrier pipe is a flexible alternative to copper tube. It is suitable for both hard and soft water areas and incorporates an oxygen diffusion barrier to stop the ingress of any oxygen in to the system.

    Manufactured to the highest possible standard this pipe is suitable for use in both underfloor heating and radiator central heating systems as well as domestic hot and cold (potable) water services.

    It connects easily to copper pipe using push-fit fittings however please note the polyplumb system is not suitable for the transportation of gases..

    Polybutylene pipe is used to create the most flexible jointing systems. It offers exceptional durability and long term performance which has made it become the preferred material choice for today's building projects.
    Another key advantage of Polybutylene pipe is that it is extremely lightweight compared with the copper piping systems.

    Polybutylene pipe has a good resistance to freezing temperatures, maintaining long term durability in heating and water applications. This combined with the flexibility of the pipe, means that if water is subjected to freezing temperatures, a burst pipe is less likely.

    Polypipe Barrier Pipe

    Cutting the Polyplumb Pipe

    When cutting the Polypipe pipe make sure it is not scored or scratched in any way. A polypipe pipe cutter must always be used (PB781). The pipe is to be cut squarely using the "K" marks on the pipe as a guide. The "K" marks indicate when the pipe has been inserted into the fitting correctly.

    Using of pipe stiffener

    Insert a pipe stiffener into the pipe (not required on copper pipe). Pipe stiffeners are an integral part of the joint when using Polypipe grey pipe with either Polyplumb fittings or compression fittings and need to be fully inserted into the pipe end. Polypipe offer 2 types of pipe stiffener to be used with Polyplumb fittings - metal and plastic. When using a pipe stiffener, ensure it is fully inserted before applying the fitting

    Insert pipe fully into fitting

    Insert the pipe into the fitting, ensuring it is inserted to the full socket depth denoted by the next "K" mark on the pipe.

    Check Joint Security

    A quick tug on the pipe will confirm that the pipe is interted past the grab ring and that grab ring was present in the fitting. It does niot however ensure that the pipe is fully inserted as this can only be confirmed by using the depth insertion mark.
    Please Note: Do not re-joint. If a joint has been dismantled, it should not be re-jointed as there is a risk that the outer edge of the grab ring will have become damaged and this will reduce the pull-out performance of the joint when subjected to pressure.
