The Snyder Industries 8750 Gallon ASTM XLPE Vertical Storage Tank (SKU 5360100N40) is a crosslinked linear polyethylene (XLPE) bulk storage tank rated to 1.5 specific gravity, so it holds heavier-than-water contents without derating the wall. It stands 146 inches tall on a 142 x 142 inch footprint, giving you a full 8,750 gallons of vertical storage in a single vessel finished in Natural White. Because the wall is crosslinked rather than standard HDLPE, it carries more impact and environmental stress-crack resistance, which is why buyers searching for a durable vertical storage tank or XLPE tank land on this Snyder unit.
Will it work for your site
Plan around real loaded weight, not just gallons. Filled with water this tank carries roughly 72,975 pounds; at its full 1.5 specific-gravity rating the contents can reach about 109,462 pounds. That load has to sit on a fully supported, properly engineered pad — run your numbers through the Tank Sizing Calculator and confirm the base against the concrete pad sizing framework before you set it. The technical drawing on this page shows the molded-in fitting layout: a flange, an 18-inch polyethylene threaded/vented fitting at the top, two flat-mount fittings at distinct clock positions (2.5 degrees and 92.5 degrees), an S.U.M.O. fitting, and a bulkhead, plus a manway with 15-inch access for interior inspection and cleaning. Verify each fitting size and clock position against your own plumbing plan, and confirm both flat-mount locations rather than assuming a single sidewall port.
Fittings, venting, and sealing
The 18-inch threaded/vented fitting is your top vent, and it matters: on a vessel this size, adequate venting must stay open during rapid fill and draw so you never pull a vacuum or pressurize the XLPE wall. Flange and bulkhead connections are the number-one leak source on poly tanks, so match your gasket material to the fluid you are storing and torque every bolted joint to spec. The 15-inch manway access is the entry point for interior inspection and cleaning on a 146-inch-tall tank where reach is limited — plan your inspection routine around that opening.
Common sizing mistakes to avoid
The most frequent error on a tank this large is under-building the foundation or ignoring freeboard. A vertical XLPE tank must be filled from the top and supported fully across its 142-inch base — spanning it or setting it on soft ground invites uneven loading and stress on the wall. Note that the 1.5 SG rating means the wall holds heavier-than-water contents without derating; it does not by itself certify any specific chemical service, so keep this unit on water and fire-water duty. If you are using it as a fire-water reservoir, size the usable volume to your draw requirement rather than nameplate capacity — the NFPA 22 reservoir design guide and the Tank Sizing Guide walk through how to reserve dedicated volume and protect against freezing in cold-climate service.
