The Norwesco 2635 Gallon Horizontal Elliptical Leg Tank in black is built for the road and the field. The elliptical cross-section keeps the center of gravity low across its 140-inch length and 90-inch footprint, with molded support legs that cradle the tank in a fitted trailer or skid cradle. This is the tank applicators reach for when they need to move fertilizer, water, or compatible solutions to where the work is happening.
Will it work for your job?
This is a 2,635-gallon polyethylene horizontal leg tank measuring 72 in high by 90 in wide by 140 in long, molded in black. It carries a 1.5 specific gravity rating, so it is built to haul liquids up to 1.5 times the weight of water. Run the numbers before you load: full of water this tank holds roughly 21,976 lb of contents, and at its 1.5 SG rating it is engineered for up to 32,964 lb of liquid weight. That load has to ride on a trailer or platform rated to carry it, with the legs fully and evenly supported. Use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity to your axle and frame ratings before you commit. If this is a fertilizer haul, the Norwesco applicator and leg tank guide walks through DOT non-roadable trailer scope, and the fertilizer-blend stratification guide covers keeping a mixed load from salting out before the spreader runs off-spec.
Chemical compatibility
This is a polyethylene leg tank rated to 1.5 specific gravity. Always verify your specific chemical, concentration, and temperature against the OEM chemical-resistance chart, which is concentration- and temperature-specific. Within the 1.5 SG rating, this tank is compatible with the following at the listed concentrations, paired with the noted fitting and gasket materials:
- Acetic Acid at 60% — PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% — PVC fittings, EPDM gaskets
- Calcium Chloride at 40% — PVC fittings, EPDM gaskets
- DEF at 32.5% — 316SS fittings, EPDM gaskets
- Ferrous Sulfate at 20% — PVC fittings, EPDM gaskets
- Magnesium Chloride at 30% — PVC fittings, EPDM gaskets
- Sodium Carbonate at 30% — PVC fittings, EPDM gaskets
- Urea Solution at 50% — PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM — PVC fittings, EPDM gaskets
Match wetted hardware to the chemical, not the tank. Note that DEF takes 316SS fittings, not PVC, while most of the salts and sulfates above run on PVC with EPDM gaskets and the acetic acid and urea solution want PP/PVC. The biggest mistake to avoid is overrunning the SG rating. Heavier or more aggressive chemicals — ethylene glycol, ferric chloride, ferric sulfate, hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, peracetic acid, phosphoric acid, polyaluminum chloride, potassium carbonate, potassium hydroxide, propylene glycol, sodium bisulfate, sodium bisulfite, sodium hypochlorite, sodium thiosulfate, sulfuric acid, and zinc orthophosphate — call for a higher 1.9 SG tank rather than this 1.5 SG model. Several of those also need Viton or Aflas gaskets instead of EPDM (Viton for the strong acids and oxidizers such as hydrochloric, sulfuric, and sodium hypochlorite; Aflas for peracetic acid), so verify gasket material along with the tank rating. Check the full list and per-chemical details on our chemical compatibility pages before you commit to a service.
Freight and ordering
This 2,635-gallon Norwesco horizontal leg tank ships LTL freight, quoted live to your ZIP from the nearest Norwesco plant — Griffin, GA; Hanford, CA; Lancaster, OH; Shawnee, OK; St. Bonifacius, MN; or Tooele, UT. Because freight on a tank this size depends on origin and destination, run your ZIP through the Freight Cost Estimator for a real number, and review the technical drawing on this page for fitting locations and exact dimensions before you order.
