4" Flap Gate Stainless Steel for CMP, PVC & Corrugated Plastic

Rugged steel construction ensures a longer life and helps keep drainage systems from flooding.

• Designed for use on PVC, CMP, and corrugated plastic tubing.
• Band fits approximate pipe O.D. of 3.85" to 5.1". See spec sheet below for full details.
• Constructed of 304 stainless steel. Great for use where water is caustic, acid, corrosive, salt, or pH below 5 pH or above 9 pH.
• Flap Gate does not have a gasket and is not watertight.
• Flap should sit flush against the pipe, not the band, to ensure optimal performance.
