Chemical Compatibility & Specific Gravity
Polyethylene tanks have specific gravity ratings. SG 1.0 = water-rated. Higher SG = denser fluid handling. Always match the stored liquid's density to the tank's rating.
| Fluid | SG | Rating |
|---|---|---|
| Water, potable | 1.00 | Fully rated |
| Ag liquid fertilizer (10-34-0) | 1.40 | Within rating for SG ≥ 1.5 tanks |
| Saturated brine | 1.20 | Within rating |
| 12.5% sodium hypochlorite (bleach) | 1.20 | Within rating; UV exposure reduces bleach shelf life |
| Sulfuric acid, <30% | 1.25 | Within rating for XLPE tanks only; confirm with our team |
| Diesel fuel, motor oil | 0.85–0.90 | NOT rated — permeation concern |
| Concentrated acids (>30%) or strong solvents | varies | NOT rated — material attack |
For fluids not listed, call 866-418-1777 — we maintain a chemical compatibility chart that cross-references manufacturer material science with real field performance.
Typical Applications
- Batch-mixing chemistry requiring complete drain
- Hydroponic nutrient solution holding
- Food-grade brine and liquid-sugar holding (verify FDA rating)
Installation Checklist
- Match the stand to the cone degree (15°, 20°, 30°) — stands are NOT interchangeable
- Use a full-port ball valve on the drain to avoid stalling viscous liquids
- Bolt the stand to the pad; do not rely on weight alone for lateral stability
Shipping & Freight
Ships LTL on a pallet. Residential deliveries need liftgate service. Call with your ZIP for exact freight.
Warranty & Certifications
1-year limited warranty (2-year on select industrial models). Keep your One Source Plastics order confirmation — it's the warranty-claim trigger.
When This Product Is the Wrong Choice
- Used with stands of the wrong degree — cone-bottom stands are NOT interchangeable across 15/20/30 degree families
