4 in. Polypropylene DWV Coupler



The FLEX-Drain 4 in. Polypropylene DWV FLEX-Drain Coupler is ideal for connecting 2 cut pieces of FLEX-Drain (not included). The FLEX-Drain system helps you get the job done faster and easier, with professional grade durability and more versatility than traditional corrugated pipe. Flexible and expandable, FLEX-Drain easily bends around any obstacle, holds its shape during installation and with a simple snap, its integrated soil-tight fittings lock securely and stay connected during backfilling. FLEX-Drain is a complete drainage solution system that's widely compatible with virtually all traditional 3 in. and 4 in. corrugated pipe and 4 in. PVC. Technologically superior, it's made with no-break copolymers and exceeds all applicable ASTM crush standards.
