ADS Dual Wall 4" Coupler

ADS Dual Wall 4" Coupler

The ADS® N-12® 0413WT dual wall coupler is a watertight, injection-molded HDPE coupler made to join 4" ADS N-12 dual wall pipe with a secure bell connection. Because it’s HDPE, it stays less brittle than PVC in cold weather, shrugs off impacts from backfill rocks, and resists a wide range of soil and chemical conditions—so the coupler can be the dependable part of the job (even when the weather isn’t).
