The Snyder Industries 60 Gallon ASTM XLPE Black Double Wall Tank is a self-contained containment vessel built from crosslinked linear polyethylene (XLPE) and rated to a 1.9 specific gravity. The integral outer wall provides secondary containment around the inner tank, so one unit handles both storage and spill capture without a separate basin. Its 26" x 26" footprint and 41" height fit tight equipment rooms and curbed pads where floor space is scarce - just size the curb or pad around the unit so it can capture the inner-tank volume if the outer wall is ever breached.
Will it work for your job
The inner tank holds 60 gallons. Plain water at full volume weighs about 500 lb, and the tank is rated to carry up to 951 lb of contents - that headroom is what the 1.9 specific gravity rating buys you. Worked the other way, 951 lb across 60 gallons puts the ceiling near 15.8 lb per gallon, so you can check your liquid's density against that figure directly rather than guessing. Confirm your numbers with the Tank Sizing Calculator and the Tank Sizing Guide before you order.
Ports and access
This tank ships with two top connections only - confirm any side outlet, bulkhead, or additional gaskets against the technical drawing before ordering:
- Fill / vent: 14" PE threaded/vented fitting
- Access: manway with an 11-3/8" opening for gauging, inspection, and reaching inside to clean
For exact port locations and overall dimensions, see the technical drawing on this page.
The mistake to avoid
On a double wall XLPE tank, the specific gravity rating is the number that matters most. This unit is rated to 1.9, which covers water and many heavier liquids, but the wall is engineered around contents weight, not volume alone - stay within the 951 lb max-rated contents figure. The XLPE resin and the secondary containment make this a containment-grade vessel, but always confirm your liquid against the manufacturer's chemical-resistance chart at your actual concentration and temperature before placing it in service. The 11-3/8" manway opening also sets how easily you can inspect the interstitial space and inner wall over the tank's life, so plan your maintenance access around it.
