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
- Bulk liquid storage at SG up to the tank's rating
- Fertilizer and ag-chemical storage at dealers/co-ops
- Industrial process chemicals (verify compatibility first)
Installation Checklist
- Install on a flat, level pad extending 6 inches beyond the tank footprint
- Fit a top-vent to prevent vacuum collapse on high-flow draw
- Size overflow fitting at 1.25x the fill rate
- Verify SG rating matches your stored liquid BEFORE filling
- Budget for crane or forklift offload — manual handling above 1,000-gal capacity is not feasible
Shipping & Freight
Ships LTL. Expect a 53-foot delivery truck — confirm road-access clearance.
Warranty & Certifications
3-year limited full-replacement. Keep your One Source Plastics order confirmation — it's the warranty-claim trigger. Certifications on file: FDA Approved, NSF 61.
When This Product Is the Wrong Choice
- Pressurized service — these are atmospheric-vent-only tanks
- Storing fluid beyond the tank's SG rating — load the wrong density and the walls fail early
