The Snyder 400 Gallon Crosslink Vertical Storage Tank (SKU SII-1740000N42) is a white cross-linked polyethylene vertical tank built for demanding bulk-storage duty. It stands 64 inches tall on a compact 45 x 45 inch footprint, holds 400 gallons, and carries a 1.9 specific gravity rating - which is why buyers searching for a heavy-duty vertical storage tank or a 400 gallon tank keep landing here rather than on a standard 1.5-rated water tank.
Will it work for your site?
Filled with plain water, this tank weighs about 3,336 pounds; its shell is rated to carry contents up to 6,338 pounds, so the 1.9 SG rating gives real headroom over water service. The crosslink (XLPE) wall is the reason for that higher rating - it is a tougher, more impact- and stress-crack-resistant resin than standard HDPE, which matters when a tank is filled, drained, and refilled continuously. The fittings shown on the technical drawing on this page include an 18-inch PE threaded and vented opening at the top (the fill and vent point), a 6-inch x 8-inch fitting suited to outlet or drain service, a flange, and a manway for interior access and cleaning. Because the footprint is a compact 45 x 45 inches, plan your pad accordingly - use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the tank matches your volume and drawdown needs before you order.
How it ships
This tank ships by LTL freight from Snyder Industries' plant in Lincoln, Nebraska, and freight is quoted live to your ZIP code - it is not included in the list price. Standing 64 inches tall on a 45-inch base, it crates as a single oversized piece, so confirm your door and structure clearances and arrange a lift gate or on-site equipment for offloading in advance. Get a real number in seconds with the Freight Cost Estimator, or call 866-418-1777 and we will quote it for you.
The mistake to avoid
Do not treat the 1.9 SG rating as license to store anything heavy without checking the resin. This is a water and general-storage vertical tank; crosslink polyethylene is a structural upgrade, not a chemical-compatibility guarantee. If you are considering anything other than water, confirm the chemical against an OEM chemical-resistance chart at your concentration and temperature, and match your wetted elastomer parts - the gaskets on the vented 18-inch fitting and the manway - along with the fitting materials, before filling. For above-ground installs, connect the 3,336-pound full-water load over that 45 x 45 inch footprint to real bearing pressure: our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework, and if this is a rural fire-protection reservoir, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
