Our product range has evolved over time and continues to change to provide our loyal customers with the most advanced products relative to their sector.


Qual-PEX cross-linked poly-ethylene barrier pipe from Pipelife is truly a first in this generation of thermoplastic pipes – being the first PEX pipe ever to have been approved to the BS 7291 kitemark and also holding WRAS and Irish Agrément Board approvals.
