The Snyder Industries 35 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a compact crosslinked polyethylene vertical tank built for demanding storage in a small footprint. Its 22" wide x 22" deep x 36" tall envelope holds 35 gallons on a 22" x 22" base, so you can check clearance before it arrives and drop it into tight utility corners, skid frames, and pump stations where a full-size vertical tank will not go.
Will it work for your job
This is a crosslinked linear polyethylene (XLPE) vertical storage tank rated to a specific gravity of 1.9, meaning the wall is engineered to carry contents up to 1.9 times the density of water. In plain terms, water weighs about 8.34 lb/gal, and this tank is built to hold liquids up to roughly 15.8 lb/gal. Full of plain water it carries about 292 lb; at its maximum rated 1.9 SG contents it is built to hold roughly 555 lb, so the pad and stand you set it on need to be sized for that loaded weight, not the empty shell. If you are matching tank volume to a fill rate or a reserve requirement, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.
Fittings and how to plumb it
It ships with a 6" PE threaded, vented fitting and a cap with a 4.5" access opening for filling and inspection. Two numbers drive your plumbing: match the 6" PE threaded port with a matching 6" gasketed cap or threaded adapter, and treat the 4.5" access opening as the maximum diameter for any lid-mounted vent or gauge you add. Size your gasket and cap to those two dimensions before you order plumbing, and confirm the exact fitting layout against the technical drawing on this page.
Why XLPE on a 35 gallon vertical
Crosslinking is what separates this from a standard HDPE storage tank. The polymer chains bond across each other during rotational molding, which raises impact and environmental stress-crack resistance in the wall. That is why Snyder rates it to the higher 1.9 SG, and that rating is the fact that decides which liquids qualify. If you are weighing whether crosslinking earns its keep for your contents, read Snyder XLPE vs HDPE: When Crosslinking Matters. If your service calls for secondary containment, the Snyder Captor double-wall freeboard sizing guide walks through the step-up path. For anything set on a slab, size the base correctly using our concrete pad sizing framework.
The mistake to avoid
Do not undersize the support or the pad for the loaded weight. At 22" x 22" this vertical tank concentrates up to 555 lb of rated contents onto a small footprint, so a flimsy stand or an uneven surface is the failure point, not the tank. Set it dead level on a full-contact base.
This 35 gallon Snyder vertical storage tank ships LTL from the Snyder plant in Marked Tree, Arkansas, with freight quoted live to your ZIP. Because the empty XLPE shell ships light, the LTL quote is driven by the dimensional freight class of the 36"-tall crate rather than by weight, so a small tank can still carry a real freight line.
