Polyethylene drainage pipe fittings are made with high-density polyethylene (HDPE) polymers, connect to pipe to transport water, chemicals, oil, and gas in bulk water distribution, chemical processing, and industrial water treatment. These fittings are nonperforated for use with corrugated drain pipe. HDPE offers excellent chemical resistance, resists gentle oxidants and reducing agents, and provides high-impact resistance at very low temperatures. Drainage pipe fittings come in a variety of shapes and sizes.
