French Drain Man HDPE 4 in Corrugated Pipe External Snap Coupler, Heavy Duty, Dual Wall, Lifetime Guaranteed

The point where you connect two drainage pipes is the typically the weakest part of any system. We now have an extra heavy duty external coupler that makes the connection the strongest part of the drain system. Our external snap coupler has eight spring-loaded barbs that grab the corrugated pipe. This is dual wall drainage pipe. Corrugated on the outside and smooth on the inside. This is guaranteed to never crack or break. It will withstand the freeze and thaw in the north and it'll take ground shifting and sinkholes in the South. This the strongest external coupler on the market and we offer a lifetime guarantee against breakage.
