For home water lines, PPR suits hot mains and exposed risers — it is heat-fused, rigid and rated for roughly 95°C continuous — while PEX suits fast, flexible installs and retrofits, tolerates freezing better and is joined by crimp or clamp. Choose PPR for durable hot lines, PEX for speed and tight spaces.
| Property | PPR | PEX |
|---|---|---|
| Max continuous temp | ~95 °C (203 °F) | ~82 °C sustained (bursts ~93 °C) |
| Cold-water pressure class | up to ~PN25 | around 10 bar / PN10 |
| Joint method | heat fusion (welded) | crimp / clamp fittings |
| Flexibility | rigid | flexible, bends around corners |
| Freeze tolerance | lower | higher (expands) |
| Typical service life | 50+ years | 40–50 years |
| Relative cost / m | higher | lower |
Typical industry values for planning — confirm exact figures against the manufacturer datasheet and local code before ordering.
Hot-water mains and risers, exposed pipework, high-temperature or chemically demanding lines where a welded joint and long life matter.
Retrofits and renovations, long flexible runs, freeze-prone areas, and jobs where fast installation and fewer fittings win.
