N-12® ST IB (soiltight) Pipe

Available in diameters from 4" to 60", N-12 pipe is replacing reinforced concrete pipe as a preferred product for storm water applications.

The reinforced polyethylene bell of N-12 ST IB pipe minimizes distortion. Chipping and cracking common to concrete pipe bells, is eliminated.

Today N-12 ST IB pipe is the best soil tight joint for storm sewers on the market.

With bell & spigot designs you simply lube and push together, field installation is a snap
Unlike pipes from other manufacturers, there are no additional gasket materials, grout or sealing bands to transport and apply.
In-line bell design means no need to dig bell holes - and no worries about improperly dug bell holes that can dip or sag, leading to bell shear.
Noticeably faster installation times
Lower labor costs
