Fine Slot N-12® Pipe is HDPE drainage pipe that offers joining ADS perforated pipe & sock systems for use in agricultural applications and subsurface de-watering.

The pipe is available in 12”, 15”, and 18” (300-450 mm) diameters and contains a superior built-in bell-and-spigot joint. The joints are sealed by high-quality, factory-installed rubber gaskets.

The pipe is designed with fine slots in the valleys of the pipe. 20” (6m) or 13’ (4m) lengths are available. Joint design is bell-and-spigot with an in-line bell design. Fine Slot N-12 Pipe has exceptional joint strength and excellent abrasion and corrosion resistance. It is lightweight and can be installed quickly.

The interior walls are smooth for hydraulic efficiency. The structural strength will support H-25 live loads with 12” (300mm) minimum cover.

Fine Slot N-12 Pipe design minimizes soil infiltration and allows for drainage. It comes in a variety of diameters and lengths that will fit any project. The joint only requires lube for fitting, the ends are easily pushed together for easy field installation.

Unlike pipes from other manufacturers, there aren’t any additional gasket materials, grout or sealing bands to transport and apply. Fine Slot N-12 Pipe is made from HDPE and has been shown to have long-term durability in the field.
