A 4950 gallon 15 degree cone bottom tank for heavy liquids under a low roof
Part number 45383 is Norwesco's 4950 gallon cone bottom tank with a shallow 15 degree cone, moulded in light blue high density linear polyethylene at the heavy duty 1.9 specific gravity rating. It is 102 inches in diameter and 159 inches tall, and weighs 1480 lb empty. The cone drains to a 3 inch polypropylene female NPT bulkhead fitting at the point, and a 16 inch threaded vented manway on top takes the fill line and lets air in and out. The 1.9 rating covers liquids up to 1.9 times the weight of water: 4950 gallons of water weighs 41283 lb, and at the 1.9 rating the contents can run to 78438 lb. The resin is FDA compliant per Norwesco, the service limit is 120 F, and Norwesco backs the tank with a 3 year warranty. A cone bottom tank needs its stand; Norwesco's stand for this tank is N-62473, sold separately. The tank ships from Norwesco's Albertville, Alabama plant.

Why the 15 degree cone
A cone bottom tank drains completely through its low point, which is why it is bought for slurries, blends that separate, and chemicals you do not want sitting in a dead zone. The 15 degree cone is Norwesco's shallowest. It drains more slowly than a 30 or 45 degree cone and leaves a little more film on the wall, but it stands shorter at the same volume, and under a building roof that is often the deciding number. Our guide to choosing between 15, 30 and 45 degree cones sets the three against each other, and the complete buyer's guide to the 4950 gallon 15 degree cone bottom tank goes deep on this size. If you are still choosing between a cone, a vertical and a horizontal body, start with our overview of Norwesco tank shapes by use case, then settle the volume with the tank sizing calculator and the tank sizing guide.
Polyethylene suits water, most fertilizers and many common chemicals. Check yours in our chemical compatibility guide; cone tank buyers most often ask about sulfuric acid, sodium hypochlorite, hydrochloric acid, phosphoric acid and urea solution. Each entry names the fitting and gasket material to order, which matters on a cone because the one outlet sits at the lowest point and is always wet.
Openings, fittings and what to check before you buy
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting at the point of the cone. Your valve threads straight into it; support the valve and the first length of pipe from the stand or the floor so the fitting carries liquid, not hardware.
- Manway. A 16 inch threaded vented manway. The vent is part of the lid and must stay clear; a tank drained through a 3 inch port pulls in air as fast as liquid leaves.
- The stand. N-62473, sold separately. A 15 degree cone sits only in a 15 degree stand. Our cone bottom stand compatibility matrix lists the pairings.
- Height. 159 inches for the tank alone. Add the stand and the room to open the manway before you commit to a ceiling.
- Drawing. Norwesco's drawing for this tank is linked under Technical Drawing on this page.
The same tank at the standard rating, and sizes nearby
For water and liquids no heavier than 1.5 specific gravity, the same tank in white at the standard rating is the 4950 gallon 15 degree cone bottom tank, part 45381. If you want a steeper cone, the 5500 gallon 30 degree cone bottom tank in blue, part 40316 is the next size up, and the 3000 gallon 30 degree cone bottom tank, part 40170 is the step down. Each page carries its own dimensions and stand.
Shipping and receiving
The tank ships as an oversize load, 159 by 102 by 102 inches and 1480 lb, from Norwesco's Albertville, Alabama plant. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote for a job that needs paperwork. Plan a forklift or crane with straps to unload it. Set the stand level across both diagonals first, set the tank, turn it so the outlet points where the pipe runs, fit the valve, and fill with water the first time so any problem shows up with something harmless inside. Check the part number against 45383 on the bill of lading before the driver leaves.
