The Chem-Tainer 19 Gallon PE Rectangular Open Top Tank is a compact, open-top polyethylene vessel built for hand-fill batching, parts soaking, mixing, and point-of-use water holding where a square footprint fits a bench, shelf, or floor better than a round drum. With a 19-gallon working volume in tough Chem-Tainer polyethylene, this open tank gives you full top access for dipping, manual addition, and easy cleanout - the practical reason most buyers choose a rectangular open top tank over a closed cylinder.
Will it work for your job?
This is a water-service rectangular open top tank rated at 19 gallons. Filled to the top with water, plan for roughly 158 lb of total weight on whatever surface holds it - so a sturdy bench, shelf, or pad matters more than people expect on a tank this small. The empty-to-full swing is what catches buyers out, so size your support to the full figure, not the empty one. Check the overall length, width, and height on the technical drawing on this page against your available footprint and against any lid or cover you plan to fit, since footprint is the whole reason to pick a rectangular tank. If you're unsure whether 19 gallons matches your batch or holding cycle, run the numbers with our Tank Sizing Calculator or read the Tank Sizing Guide before you commit.
What buyers get wrong on small open tanks
The open top means there's no factory-installed fitting set on this tank - you fill from above and either dip product out or add a bulkhead fitting yourself if you want a drain. If you do, match the bulkhead fitting and gasket to the wall thickness shown on the technical drawing, and rate the gasket to whatever you hold. The other common mistake is treating an open top water tank as set-and-forget: because the top is open, anything stored in it is exposed to dust, splash, evaporation, and freeze in cold spaces. If this tank sits outdoors or in an unheated building, plan for freeze protection. Open-top vessels also have less structural stiffness than a closed tank, so don't move it full, don't stack load on the rim, and keep it on a flat, fully supported surface. For above-ground siting on a pad, our concrete pad sizing guide covers full-support principles that apply even at this small scale.
Freight and ordering
This tank ships LTL from the Chem-Tainer plant in West Babylon, NY, with stock also flowing through New York and Pennsylvania. At 19 gallons it's a small unit, but rectangular open top tanks ship LTL freight quoted live to your ZIP rather than carrying a flat freight figure - get your exact number with the Freight Cost Estimator or call us at 866-418-1777. If you're spec'ing several tanks across a water-handling setup, our team can size the order and the freight together. Listed price is before freight; the estimator gives you the LTL freight cost to your ZIP so there are no surprises.
