Metric sizes for international use
PPR Fittings are available in metric sizes. Common sizes include 20mm, 25mm, 32mm, and 40mm. Larger sizes go up to 160mm. Example: a 25mm fitting for a 25mm pipe.
Imperial sizes for North America
In North America, imperial sizes are available. Standard sizes include 1/2 inch, 3/4 inch, and 1 inch. Larger sizes go up to 4 inches. PPR Fittings are available in imperial sizes.
Corresponding pipe diameters
The fitting size matches the pipe's outer diameter. A 25mm pipe requires a 25mm fitting. A 1-inch pipe requires a 1-inch fitting. PPR Fittings match the pipe exactly.
Pressure ratings: PN10, PN16, PN20
PPR Fittings typically have PN10, PN16, or PN20 ratings. PN10 means 10 bar (145 psi) at 20°C. PN16 means 16 bar (232 psi) at 20°C. PN20 means 20 bar (290 psi) at 20°C. Example: PN20 for high-pressure systems.
Pressure rating at higher temperatures
Pressure ratings decrease at higher temperatures. At 60°C, PN20 drops to 10 bar. At 80°C, it drops further. PPR Fittings require derating for hot water.
Example: residential plumbing
A home uses 25mm PPR Fittings for water supply. The fittings are PN20 rated. The system handles 10 bar. Example: a reliable water supply system.
Example: commercial building
A commercial building uses 40mm PPR Fittings. The fittings are PN16 rated. The system handles 8 bar. Example: a reliable commercial system.
Example: industrial piping
A factory uses 63mm PPR Fittings. The fittings are PN20 rated. The system handles 10 bar. Example: a durable industrial system.
SDR and pressure rating
Pressure rating relates to SDR. Lower SDR means thicker walls and higher pressure. PPR Fittings with lower SDR handle higher pressure. Example: SDR 6 for PN20.
Standards and certifications
PPR Fittings meet DIN and ISO standards. They are certified for various applications. Example: DIN 8077 and 8078.
Final sizes and pressure summary
PPR Fittings come in metric and imperial sizes. Common sizes are 20mm to 160mm. Imperial sizes are 1/2 inch to 4 inches. Pressure ratings are PN10, PN16, and PN20. Ratings decrease at higher temperatures. PPR Fittings are available for all applications. Example: choose the right size and rating for your system.
