Our range of premium 25mm pex-al-pex pipe is manufactured to ISO9001 European standards ensuring outstanding performance & reliability in all types of warm water applications.
5 layer pex-al-pex pipe offers unrivalled suitability for potable water and plumbing applications by combining the best elements of a plastic and metal pipe into one product.
The aluminium core provides strength and importantly acts as an oxygen barrier to stop the ingress of oxygen into the system causing premature wear (corrosion) to the manifold. The aluminium layer also makes the pipe form-stable, making it very easy to work with by eliminating spring back for easier installation.
WRAS approved Pex-Al-Pex pipe can be used in plumbing and potable water applications whereas EVOH pert pipe can only be used with low temperature underfloor heating systems.
Pex-Al-Pex pipe key features:
- 5 layer composite pipe using PEX inner and outer layers with a 0.25mm thick edge-welded aluminium core
- Butted welded manufacturing method
- Can be formed by hand and maintains its shape- perfect for underfloor heating pipework
- High temperature resistance- a maximum sustained working temp up to 70°c & maximum transient temperature up to 85°c
- Manufactured to meet CE & ISO9001 European & International standards
