    Wefatherm piping for 410a refrigerant


    Can i get some opinions/experience on Wefatherm piping please, as to whether it's a good replacement for refrigerant copper, to be used on splits, multi's VRF's etc.
    All good or bad comments welcome. Have not used it before on any A/C systems and was just wondering if it is compatible with 410 and how install friendly it is.
    The Wefatherm piping i'm referring to is the soft coiled aluminium composite variety......

    Many Thanks

Pipes with a thicker wall offer improved pressure / temperature performance than thinner walled pipes, allowing installers to tailor WEFATHERM systems to the specific requirements of the applications.
    PP-R, PN10, SDR11
    • Thin wall, Size Range 20 – 125mm (o.d.)
    • Suitable for cold water systems only.
    • 10 Bar pipe. Please refer to the technical catalogue for maximum operational pressures and temperatures.
    PP-R 80, PN16, SDR7.4
    • Medium wall, Size Range 16 – 160mm (o.d.)
    • Suitable for hot and cold water, central heating systems.
    • 16 Bar pipe. Please refer to the technical catalogue for maximum operational pressures and temperatures.
    PP-R 80, PN20, SDR6
    • Heavy wall, Size Range 16 – 125mm (o.d.)
    • Suitable for hot and cold water, central heating systems.
    • 20 Bar pipe. Please refer to the technical catalogue for maximum operational pressures and temperatures.
    WEFATHERM Fibre-Pipe

    WEFATHERM Fibre-Pipe is a composite pipe manufactured of PP-R and including a special glass fibre inner layer that offers advantages in the form of drastically reduced expansion while offering an increased pressure rating, making it ideally suited for high temperature applications.

    Well, reading the blurb above it is not suitable for the application you propose...
    What more answers are you after?


    regards to install? N/A
    operation? Likely to burst as operating pressures well above the manufacturers recommended pressures and chemical compatibility not been proved.
    sustainability? See previous comment.

    Re: Wefatherm piping for 410a refrigerant

    The info provided by install monkey is the piping for cold water, central heating systems, plumbing etc.
    I am aware that this is not compatible with running pressures of A/C. I am asking if anyone has used, installed, can comment on the soft coil ali variety that i referred to in my original post.......................

    I can't find any reference to refrigerant pipework on the manufacturers website.

    I would suggest therefore that you investigate where and by whom this alleged product is made and report back.

    BASIC MAINTENANCE. If it doesn't move and it should then use WD40. If it moves but it shouldn't then use Duct Tape.

    Wefatherm pipes seem to be for secondary and not primary refrigerants.
    Mostly found in Oxfordshire, UK :)

    I have used the Aquatherm version for water heating. It is nice but takes some getting used to. The aluminum is not a structural component, only an oxygen barrier.
