1635 Gallon Heavy Duty Black Elliptical Leg Tank

The Norwesco 41890 1635 Gallon Heavy Duty Elliptical Leg Tank is engineered for demanding liquid transport and storage applications. Manufactured using high-density linear polyethylene, this tank offers superior impact resistance, chemical compatibility, and long-term durability. Molded-in legs act as internal baffles, reducing sloshing and improving stability during transport.

Designed for use on trailers, trucks, agricultural equipment, and stationary setups, this tank is suitable for water, fertilizer, and liquid chemical handling. The heavy-duty 1.9 specific gravity rating allows safe containment of heavier liquids.

This tank includes a 16" vented manway, 2" outlet fitting with a siphon tube, and UV-resistant black polyethylene to protect contents from sunlight exposure. As with all Norwesco elliptical leg tanks, full-length support and support bands are required for installation and warranty compliance.

Norwesco has over 82 years of experience and was the first polyethylene tank manufacturer to receive NSF/ANSI 61 certification for potable water tanks, ensuring industry-leading standards and quality.
