120-gallon natural white storage tank built for heavy-duty industrial chemical containment. Manufactured by Chem-Tainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 16.7 pounds per gallon. Dual FDA and NSF 61 certified — one of the few tanks approved for both potable water and food-grade liquid storage.
The 120 Gallon PE Rectangular Open Top Tank is designed for farms, ranches, small businesses, and residential properties needing reliable mid-range liquid storage. The 120-gallon capacity hits the sweet spot for heavy-duty industrial chemical containment — large enough to be genuinely useful, compact enough to install without heavy equipment or specialized foundations.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. The 2.0 specific gravity rating means this tank is built with significantly heavier wall sections than a standard water tank — necessary to safely contain liquids weighing up to 16.7 pounds per gallon. That extra wall thickness is not optional when you are storing aggressive industrial chemicals. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. Maximum operating temperature is 120° F / 48° C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 24 inches long by 24 inches wide and 48 inches tall, requiring 4.0 square feet of level ground. Empty weight is 63 pounds. At full capacity with a 2.0 SG liquid, expect approximately 2,065 pounds on the foundation. Requires a reinforced concrete pad designed for the full loaded weight, with at least 6 inches of compacted gravel sub-base. Place on a firm, level surface free of rocks or sharp objects that could damage the tank bottom. Ensure adequate ventilation if stored chemicals produce vapors.
This tank ships without pre-installed fittings, giving you full flexibility to position inlet and outlet connections exactly where your plumbing layout requires. Use polyethylene-compatible bulkhead fittings for all penetrations. The 8" lid accommodates fill lines, vent connections, and basic interior access for inspection. We recommend schedule 80 PVC or polypropylene fittings on the NPT outlet with a ball valve for positive shutoff.
Chem-Tainer Industries has manufactured chemical-resistant polyethylene tanks in the USA since 1957. Their tanks are specifically engineered for chemical storage applications with wall thicknesses and resin formulations matched to the demands of aggressive chemicals. Backed by a 3-year manufacturer warranty from Chem-Tainer against defects in materials and workmanship under normal use conditions. FDA approved for contact with potable water and food-grade liquids. NSF/ANSI 61 certified for potable water system components. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
