The Snyder Industries 10500 Gallon HDPE Vertical Chemical Storage Tank is a large-format vessel built for bulk chemical service, rated to 1.9 specific gravity and molded from high density linear polyethylene (HDLPE) in white. At 169 inches tall on a 142 x 142 inch footprint, this is a serious vertical storage tank: a full water load weighs roughly 87,570 lb, and at its 1.9 SG rating the tank is engineered to carry contents weighing up to about 166,383 lb. That SG headroom is the whole point of this Snyder vertical chemical tank, and it is what lets you store denser chemistries that would over-stress a standard 1.5 SG vessel.
Will it work for your chemical?
Start with the resin and the rating: HDLPE at 1.9 SG. Match your stored chemistry, its concentration, and its weight to the tank rather than to the gallon number alone. To size a partial fill or confirm contents weight against the 1.9 SG ceiling, run the numbers through the Tank Sizing Calculator and review the Tank Sizing Guide. The footprint and overall height are on the spec table here, and the dimensions appear on the technical drawing on this page - confirm your slab, anchoring, and overhead clearance before you order, because at 169 inches this tank needs both vertical room and a properly engineered pad.
Chemical compatibility
This tank is HDLPE rated to 1.9 SG. HDLPE and crosslinked (XLPE) polyethylene resist different chemistries, so before placing any aggressive chemical into service confirm HDLPE vs XLPE for your application. The decisive variable is rarely the tank wall - it is the wetted fitting and gasket material, and across these chemistries the gasket elastomer splits into three families. Most services run EPDM. The oxidizers and strong acids - hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, sulfuric, hydrogen peroxide, and sodium hypochlorite - require Viton, not the default EPDM. Peracetic acid is more aggressive still and is the lone Aflas service in this set. Watch the fitting metal too: DEF, peracetic acid, propylene glycol, and zinc orthophosphate call for 316 stainless rather than PVC, so do not order plastic fittings for those. Two cautions worth flagging - sodium hypochlorite is rated to under 16.5% concentration, so higher-strength bleach is out of scope for this pairing, and strong-oxidizer services like sodium hypochlorite and peracetic acid are exactly where the wrong gasket or gauge fails. Always verify against the OEM chemical-resistance chart at your specific concentration and temperature; ratings shift sharply with both.

Spec it right the first time
On a vessel this size, the level instrument and the labeling are where chemical installs go wrong, and strong-oxidizer services like peracetic acid and sodium hypochlorite are exactly where wetted-material and gauge choices fail. Choose your gauge by chemistry - radar, ultrasonic, hydrostatic, and magnetostrictive each have failure modes in different services, walked through in Tank Level Gauge Selection for Chemical Service. Get placarding and signage right with Tank Label and Signage Compliance for Bulk Polyethylene Storage, set your sampling cadence from the Tank Chemical Sampling Protocol for Bulk Polyethylene Storage, and if you need full secondary containment compare your options in Snyder Captor Plus 110% Containment vs UL-142.
