n-12® St ib pipe (per AASHtO)N-12 pipe offers significant performance advantages, plus the best soil-tight joint in the industry. Available in diameters from 4”-60” (100-1500 mm), N-12 pipe is replacing reinforced concrete pipe as a preferred product for storm water applications.

ADS N-12 pipe contains a superior built-in bell-and-spigot joint. The joints are sealed by high-quality, factory-installed gaskets that meet all the requirements of ASTM F477. A reinforced polyethylene bell minimizes joint distortion. The chipping and cracking that is common to concrete bells is eliminated.
