A 3725 gallon black heavy duty leg tank for liquids heavier than water
The Norwesco 3725 gallon black heavy duty horizontal leg tank, part number 44049B, is a polyethylene storage tank 145 inches long, 92 inches wide and 97 inches tall, weighing 1450 lb empty. Heavy duty means the wall is built for liquids up to 1.9 specific gravity, so it carries the dense fertilizers and chemical solutions that a standard 1.5 rated tank is not meant to hold. It comes with a 3 inch polypropylene female NPT bulkhead fitting at the outlet, a 2 inch reducer threaded into it, and a 16 inch threaded vented manway on top. The resin is FDA compliant, Norwesco lists its water tanks under NSF/ANSI 61 (the listing names no models), the service limit is 120 F, and Norwesco backs the heavy duty line with a 3 year warranty. Black keeps light out of the contents, which slows algae in water and protects light sensitive liquids. 3725 gallons of water weighs 31066 lb; a liquid at the full 1.9 rating weighs close to 59000 lb in the same tank.

Where it goes
At 145 inches long this is a stationary tank. It goes on a flat, continuous pad beside the loading area, fills from a supply line or a nurse truck, and empties back out through the bottom outlet on a pump. The moulded legs carry the tank without a cradle, but every leg has to sit on the pad; a tank this heavy bridging a low spot works the wall at the leg roots. Norwesco calls for 4 support bands, band part 63284, where the tank rides on a vehicle or a skid, and the add-ons box on this page lists them. If the tank is going on a trailer, read our guide to Norwesco applicator and leg tanks for fertilizer and the DOT non-roadable trailer rules first, and the farm fleet DOT classification guide for the agricultural exemption.
What goes in it
The 1.9 rating is the reason to buy this tank over the standard version of the same shape. Liquid fertilizers, brines and many treatment chemicals weigh more than water, and the heavier the liquid the harder it pushes on the lower wall. Check the liquid in our chemical compatibility guide before the first fill; the entries for phosphoric acid, calcium chloride, magnesium chloride, potassium hydroxide and sulfuric acid are the ones heavy duty tank buyers ask about most. Keep the contents at or below 120 F. For the volume itself, use the tank sizing calculator and tank sizing guide.
Openings and fittings
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting, factory installed low in the end wall, with a 2 inch reducer already in it. Run 2 inch plumbing straight into the reducer, or take the reducer out and run 3 inch for a faster drain.
- Manway. A 16 inch threaded vented manway on top: wide enough to fill from a hose, drop a float or a suction line in, and get a hand and a brush inside to clean.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet position, the manway position and the leg layout for pad and band planning.

Shipping and receiving
The tank ships LTL at freight class 300 from Norwesco's Fairfield, Texas or St. Bonifacius, Minnesota plant, whichever is nearer you, 145 by 92 by 97 inches and 1450 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. You need a forklift or a loader to take it off the truck. At the tailgate, check the part number against 44049B on the bill of lading, walk round all the legs for transit damage, confirm the reducer is in the outlet, and fill it with water the first time before it carries anything heavier.
