420LB (120 Gallon) ASME Vertical Galvanized Steel Propane Tank
Flame King's ASME-Certified 420LB (120 Gallon) Vertical Galvanized Steel Propane Cylinder is engineered for durability and long-term use in harsh environments. The galvanized steel construction with protective zinc coating provides excellent resistance to rust and corrosion, significantly extending the tank's lifespan and reducing maintenance needs.

High-Quality Valves and Remote-Ready Gauge
The cylinder comes preinstalled with a propane float gauge that can easily accommodate a "Remote Ready Dial" (sold separately) and is fitted with high-quality valves, including a 1.25-inch ACME fill valve, service valve, and relief valve, providing safe and convenient operation.
Pre-Purged, ASME-Certified, and Ready for Use
Arrives empty, vacuum purged, X-ray and hydrostatically tested, and ready to be filled with propane. Manufactured to ASME specifications in ISO 9002-certified facilities, this tank does not require recertification after 12 years from the Date of Manufacture, offering long-term reliability and peace of mind.
Long-Lasting, Cost-Effective Construction
Built from high-grade galvanized steel, this tank resists corrosion far better than non-galvanized options. Its durable design ensures decades of service with minimal maintenance, making it a cost-effective choice for any propane application.
