PB-1 vs PEX and PE-RT: the evidence, free to download
When comparing thermoplastic pipe materials, familiarity is not the same as performance. PEX and PE-RT are widely specified, but what is the best material for your next project?
Comparing thermoplastic pipe materials? Start with the data
This technical paper sets out the evidence for PB-1 across the dimensions that matter at specification stage: long-term pressure capability, creep resistance under sustained load, Standard Dimension Ratio (SDR) advantages, and installation efficiency.
The data comes from independent testing; the conclusions are drawn from over 50 years of documented performance in pressurised piping systems.
Why PB-1 outperforms PEX and PE-RT at specification stage
Superior creep resistance
PB-1 maintains structural integrity under sustained pressure at elevated temperatures better than PEX or PE-RT — so your specification holds its ground over the life of the system.
Higher SDR, thinner walls
A higher Standard Dimension Ratio means less material per metre without compromising pressure capability: lower pipe weight, fewer fittings, easier handling on site.
Larger internal bore, lower pump energy
PB-1's thinner wall gives a wider internal diameter, enabling higher flow rates at the same operating pressure — or reduced pump energy to achieve the same flow.
Compatible with all standard jointing methods
Push-fit, compression, butt fusion, electrofusion. No system-specific constraints limiting your design or your subcontractors.
