Puddle Flanges

Puddle Flanges are specialized sealing flanges designed to prevent water leakage where pipes pass through concrete structures such as basements, retaining walls, water tanks, and manholes. Induskart provides high-quality puddle flanges manufactured from carbon steel, stainless steel, ductile iron, or PVC depending on project needs. These flanges are cast or welded with an anchoring ring that bonds tightly with the surrounding concrete, creating a watertight seal.
