A 120 gallon double wall chemical tank in black
The Snyder 5700102N51 is a double wall chemical storage tank: a 120 gallon black high density linear polyethylene primary rated for a specific gravity of 1.9, or 1,902 pounds of contents against 1,001 for water, standing inside its own secondary shell 34 inches across and 51 inches tall, weighing 100 pounds. Black keeps light off a chemical that degrades in daylight, and the double wall carries the containment a spill plan asks for inside the tank's own footprint. A 14 inch threaded, vented lid on the primary and a 3 year warranty.

Containment at day-tank scale
A day tank stands beside the dosing pump inside an occupied building, and a spill there reaches a floor drain in seconds; a double wall tank catches it in the interstitial space instead, so the tank needs no spill pallet and no berm. The SPCC 40 CFR 112 compliance walkthrough covers where a double wall tank satisfies a spill plan on its own, and how much of the nominal 120 gallons is usable once thermal expansion, chemistry and the interstice are accounted for is worked out in the Captor double wall freeboard sizing guide. The list below is the resin's rated chemistry; check the liquid at its concentration in the chemical compatibility database. The tank sizing calculator sizes the tank to the pump's rate and the refill schedule, and the tank sizing guide covers the reserve.
Snyder's small double wall tanks
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 5700102N51 (this tank, black) | 120 | 34 x 51 in | 100 lb |
| 5700102N42 (XLPE) | 120 | 34 x 51 in | 100 lb |
| 5700102N30 (sulfuric grade) | 120 | 31 x 52 in | 120 lb |
| 5991002N48 | 80 | 24 x 43 in | 80 lb |
| 5710102N30 (sulfuric grade) | 150 | 34 x 62 in | 110 lb |
The N42 is the cross-linked twin for hypochlorite and the other oxidizers. The N30 is the sulfuric acid grade, 20 pounds heavier on a 31 inch base. The 5991002N48 is the 80 gallon double wall on a 24 inch base, and the 5710102N30 is the 150 gallon sulfuric-grade tank, 11 inches taller on this same 34 inch base. The single wall 5700100N45 is the same primary without the containment, at half the weight.

Openings, alarms and the interstice
- Access: 14 inch threaded, vented lid on the primary; filled by hose or tote pump, vented outside on anything that fumes.
- Outlet: through both walls together, with the transition supported off the floor; specify the fitting for the chemical when ordering.
- Service limit: 120 F / 48 C.
Two levels to watch: the primary, with a sender chosen for the chemical per the level gauge selection guide, and the interstitial space, which is the leak alarm and gets a float switch and a logged check. A day tank is also where overfills happen, because a tote pump runs until someone stops it; the tank spillover redundancy guide covers the high-level alarm and automatic cutoff that stop a release before the containment has to catch it. A black wall hides the level, so the sender is not optional.
Where you will find one
Hypochlorite and peroxide day tanks where light is the enemy, caustic and acid feed inside occupied buildings, and any small regulated chemical tank at a site an inspector visits. One chemical per tank, labeled with a light panel on the black shell, lid closed against vapor loss.
Shipping the tank
The 5700102N51 ships palletized as LTL freight (NMFC 156600-03) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. Two people carry 100 pounds. Water-test the primary, confirm the interstice stays dry through the hold, then drain and dry before the first chemical fill. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
