20mm Blue Line metric poly pipe rated PN12.5 in a 50 metre coil, with an approximate 1.8mm wall thickness. Drinking water safe and suitable for irrigation, domestic and rural water supply, and general water distribution applications.
The PN12.5 rating means the pipe has a nominal pressure rating of 1250 kPa, or 12.5 bar, at 20°C. The allowable operating pressure reduces when used continuously at higher temperatures.
The SDR13.6 rating describes the ratio between the pipe’s outside diameter and wall thickness. For pipes of the same diameter, a lower SDR number indicates a thicker wall.
PE100 is a high-strength polyethylene grade used for pressure pipe. It is tough, flexible and resistant to rust, rot, corrosion and internal scale build-up, while its smooth internal bore supports efficient water flow.
Manufactured to AS/NZS 4130, the pipe is commonly joined using 20mm metric compression fittings. Compatible 20mm electrofusion fittings can also be used where a welded connection is preferred.

Metric pipe size identifies the nominal outside diameter. Internal diameters and wall thicknesses are approximate mean values and may vary within manufacturing tolerances.
For the same nominal size, a higher PN rating uses a thicker wall and has a smaller internal diameter. PN is the nominal pressure rating in bar at 20°C; temperature derating applies above 20°C.
