The Chem-Tainer 25 Gallon PE Cylindrical Open Top Tank (SKU TC1440AA) is a compact, natural white polyethylene open top tank built for tight footprints where you need accessible storage and easy fill-and-mix access from above. At 40 inches tall on an 18 by 18 inch base, it holds 25 gallons in a vertical cylinder that takes up barely a foot and a half of floor in either direction. The open top makes it a practical choice for batch mixing, manual filling, dipping, and any job where you reach in or pour from the top rather than relying on a sealed lid.
Will it work for your job
This is a 25 gallon white open top tank molded from polyethylene with a specific gravity rating of 2.0. Filled with water it carries roughly 208 pounds, and the SG 2.0 rating gives the wall real durability margin for water and water-based contents, with a maximum rated content load of up to 417 pounds. The footprint is 18.0 x 18.0 inches with a 40 inch overall height, so confirm you have the vertical clearance to fill and reach the open top before you place it. If you are matching this size to a storage volume or duty cycle, run your numbers through our Tank Sizing Calculator and review the Tank Sizing Guide to make sure 25 gallons fits the job. Refer to the technical drawing on this page for the dimensioned outline and wall detail.
Mounting, support, and the mistake to avoid
Because this is a tall, narrow cylinder, the most common mistake is undersizing or unleveling the support beneath it. A 40 inch column of liquid on an 18 inch base concentrates a lot of weight on a small area, and an open top tank has no closed dome to add rigidity, so it must sit on a fully supporting, flat, level surface rated for the loaded weight. Do not set it on uneven ground, partial supports, or a pad smaller than the base. If you are building a permanent foundation, our guide on concrete pad sizing for above-ground polyethylene tanks walks through getting the bearing surface right.
Open top, fittings, and freeboard
This tank ships with no factory fittings, so any outlet, bulkhead, or drain you need is a field addition. Plan each penetration as a pair: the fitting plus a compatible gasket sized to the hole you cut, so it seals against the tank wall. Remember too that an open top has no sealed lid, which means no built-in overflow control and no contamination cover. Leave fill freeboard so you do not slosh or overflow during filling and mixing, and for outdoor or sensitive contents plan a separate cover to keep debris, rain, and contaminants out.
Freight
This tank ships LTL from the Chem-Tainer plant in Hummelstown, Pennsylvania. Freight is quoted live to your ZIP code rather than baked into the list price, so get an exact number through our Freight Cost Estimator before you order, or call 866-418-1777 and we will quote it for you. The compact 18 by 18 inch footprint keeps this one manageable on a pallet, though the 40 inch height still ships best palletized for LTL handling.
