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.
