About this item

A 500-gallon ASME underground propane tank for residential installations where an above-ground tank isn't desirable. Factory cathodic coating rated for direct burial, integrated dome with locking lid, and all valves pre-installed.

Every 500 gallon underground propane tank is sourced, inspected, and serviced by our in-house technicians at our Long Beach depot before it leaves the yard. We've been supplying propane tanks to contractors, fleet operators, farmers, developers, and small businesses across North America for over a decade — so you can buy with confidence knowing the unit you receive matches exactly what you ordered.

Pricing reflects the unit only; freight to your job site is quoted separately based on your delivery zip code, site accessibility, and any crane or specialty equipment required for offload. Our logistics team will reach out within one business day of your order to confirm delivery details and finalize freight.
