The Enduraplas 1010 Gallon Black Horizontal Sump Bottom Leg Tank is a Converse, Texas-built polyethylene haul tank rated for a 1.9 specific gravity, which is what makes it a genuine chemical-service vessel rather than a water-only horizontal. It measures 130 inches long by 49 inches wide by 58.5 inches tall, holds 1010 gallons, and rides on integrated legs with a sump bottom so contents drain toward a single low point instead of pooling along the floor. The black polyethylene wall blocks UV and discourages the algae growth that plagues translucent tanks in outdoor and skid-mounted duty.
Will this tank handle my load
Run the numbers before you fill it. Full of plain water this tank carries about 8,423 pounds, and at its maximum rated contents it is engineered for up to 16,004 pounds - that headroom is exactly why the 1.9 SG rating matters when you move dense liquids. Because the service here is haul, treat the 49 x 130 inch footprint and that 16,004 lb maximum loaded figure as hard design constraints: size your trailer, skid, or pad to them and verify the loaded weight against your axle and trailer ratings before the first trip. If you are still deciding on size, the Tank Sizing Calculator and the Tank Sizing Guide walk through it. For agricultural and DOT context on running leg and applicator tanks on a trailer, see our guide on applicator and leg tanks for fertilizer and the breakdown of portable utility tanks under 49 CFR 173.5. We do not list a factory fitting or outlet configuration for this SKU, so confirm the outlet, bulkhead, and vent package by phone before you order rather than assuming a standard set is included.
Chemical compatibility
This is an HDLPE tank carrying a 1.9 specific gravity rating, which is the load spec, not a resin guarantee - confirm the resin grade (HDLPE versus XLPE) by phone before committing this tank to chemical service, because that distinction changes what the wall will tolerate. Within its SG rating, this tank is listed compatible with the following at the noted concentrations, using the indicated fitting and gasket materials. Match your fittings and gaskets to the chemical, not the tank, and treat every listing as concentration- and temperature-specific per the OEM chemical-resistance chart:
- Acetic Acid 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate 50% - PVC fittings, EPDM gaskets
- Calcium Chloride 40% - PVC fittings, EPDM gaskets
- DEF (Diesel Exhaust Fluid) 32.5% - 316SS fittings, EPDM gaskets
- Ethylene Glycol 100% - PVC fittings, EPDM gaskets
- Ferric Chloride 50% - PVC fittings, EPDM gaskets
- Ferric Sulfate 60% - PVC fittings, EPDM gaskets
- Ferrous Sulfate 20% - PVC fittings, EPDM gaskets
- Hydrochloric Acid 37% - PVC fittings, Viton gaskets
- Hydrofluoric Acid 48% - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid 26% - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide 50% - PVC fittings, Viton gaskets
- Magnesium Chloride 30% - PVC fittings, EPDM gaskets
- Peracetic Acid 30% - 316SS fittings, Aflas gaskets
- Phosphoric Acid 85% - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate 50% - PVC fittings, EPDM gaskets
- Potassium Hydroxide saturated - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate 30% - PVC fittings, EPDM gaskets
- Sodium Hypochlorite under 16.5% - PVC fittings, Viton gaskets
- Sodium Thiosulfate 40% - PVC fittings, EPDM gaskets
- Sulfuric Acid 98% - CPVC fittings, Viton gaskets
- Urea Solution 50% - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
Full details and the temperature notes live on each chemical page and on our chemical compatibility reference. If you are blending fertilizer in a tank this size, the field methods in our guide on tank stratification and mixing protocol will keep a dense blend from salting out before the spreader runs off spec.
The mistake to avoid
The single most expensive error on a horizontal leg tank is sizing fittings and gaskets to the tank instead of the chemical. The SG rating tells you the wall can hold the weight; it says nothing about what the fitting and seal in contact with the liquid will survive. Two chemicals on this list - DEF at 32.5% and Peracetic Acid at 30% - cannot run on plastic fittings at all and require 316 stainless steel, while Sulfuric Acid at 98% needs CPVC and Viton rather than the PVC and EPDM that serve most of the salts here. Mix those up and you get a leak, not a service life. Confirm the HDLPE-versus-XLPE resin grade, then match every penetration to the chemical page before you order.
