Flame King 10LB Steel Propane Tank — White Portable Cylinder with Type 1 OPD Valve, DOT-Tested

Flame King 10LB Steel Propane Tank is a 10.51 lb-capacity, DOT-approved steel cylinder equipped with a Type 1 OPD (overfilling protection device) valve for safe, everyday use with grills, fire pits, heaters, and camping gear.

This compact white propane cylinder is built from welded high-grade steel, powder-coated for weather resistance, and both X-ray and hydrostatically tested to meet DOT safety standards. Although commonly referenced in the industry as a 10 lb or 11 lb tank, its accurate fill capacity is 10.51 pounds — we use “10LB” for simplicity. The tank ships empty and ready to be filled at certified refill stations or exchanged where accepted.

How does this propane tank keep refills safer?

The Flame King tank includes a Type 1 Overfilling Protection Device (OPD) valve that limits the amount of liquid propane added, reducing the risk of overfilling and helping maintain correct vapor space inside the cylinder. The valve design is a standard safety feature required for many modern cylinders and makes the tank compatible with most Type 1 fill and exchange systems.

• OPD valve prevents overfilling and preserves required vapor space
• DOT-approved and tested for structural integrity
• Works with standard Type 1 hose assemblies and refilling stations

What materials and testing back the tank’s durability?

This tank uses welded, high-grade steel and receives a powder-coat finish to resist rust and abrasion outdoors. Each cylinder undergoes X-ray and hydrostatic testing as part of its DOT certification, ensuring pressure-holding capability and weld quality for long-term service.

• Welded high-grade steel construction for strength
• Powder-coated exterior to resist weather and chipping
• X-ray and hydrostatic testing meet DOT requirements

Will this tank work with my grill, fire pit, or heater?

Yes — the Flame King 10LB tank accepts standard Type 1 connections used on many portable grills, patio heaters, and accessory regulators. Because it is sized for portability, it’s commonly used with camping stoves, overlanding setups, and small outdoor appliances; always check your appliance’s regulator type and pressure requirements before connecting.

• Compatible with standard Type 1 regulators and hoses
• Lightweight, portable size ideal for camping and tailgates
• Use only with appliances rated for propane and matching connection types

How should I store and transport the tank safely?

Transport and store the cylinder upright in a well-ventilated area away from open flames and direct sunlight. When moving, secure the tank to prevent tipping and never store it inside living spaces or the passenger compartment of a vehicle for extended periods.

• Keep upright and secured during transport
• Store in a ventilated, shaded area away from heat sources
• Ship and refill only according to local and DOT regulations
