The Snyder Industries 300 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank is a crosslinked linear polyethylene (XLPE) vertical storage tank rated for 300 gallons, standing 82 inches tall on a compact 35 by 35 inch square footprint — overall 35 in wide by 82 in tall. Its black pigmentation blocks light penetration, and the 1.9 specific gravity rating means the shell is engineered to hold contents substantially denser than water. For a straightforward vertical tank that answers a small ground footprint without sacrificing volume, this is a heavy-duty build.
Will it work for your site?
Fill this tank with water and you are carrying roughly 2,502 pounds; loaded to its full 1.9 specific gravity rating, the contents alone can reach about 4,754 pounds. That load has to land on a properly prepared, level base — a full-footprint pad sized for the weight. Because the footprint is only 35 by 35 inches while the tank rises 82 inches, plan the pad and any anchoring for a tall, concentrated load rather than a low, spread-out one. Our Tank Sizing Calculator and Tank Sizing Guide help you match capacity to your draw-down needs, the concrete pad sizing guide walks the ACI 360R-10 framework for above-ground poly tanks, and if you are spec'ing this as a rural reservoir the fire-water reservoir design guide covers NFPA 22 sizing discipline for a tall poly vertical.
Fittings and access
The technical drawing on this page shows the outfit: a flange, two 6" x 6" fittings (one flat), an 8" PE threaded/vented fitting, and a manway with 8" access. Treat that 8-inch manway as an inspection and limited interior-service opening — it is sized for reaching in to check and clean, not for full-body entry. Confirm the plumbing and vent arrangement against the drawing before you cut anything into your installation, since the vented fitting matters for proper fill and draw, and match any bulkhead or flange gaskets and threaded-fitting seals to your stored fluid before commissioning. This 300 gallon vertical storage tank is a common choice where a tall XLPE vertical tank has to fit a tight pad.
Why XLPE — and the 1.9 SG reserve
Crosslinked polyethylene is a tougher, more impact- and stress-crack-resistant resin than standard HDPE, which is why Snyder builds this one to XLPE. Filled with water the shell is working well under its rating — 2,502 pounds against a 1.9 SG design that tolerates roughly 4,754 pounds of contents — so that headroom is what lets the same tank move up to denser fluids down the road. If you are weighing the two constructions or planning for a heavier fluid, our Snyder XLPE vs HDPE guide lays out when the crosslink earns its keep, and the Captor freeboard sizing guide explains how ASTM D1998, density, and thermal expansion set the volume you can actually use.
