Buying Guide for 20lb Propane Tanks
Material and Construction
The majority of 20lb propane tanks are made from high-grade steel or aluminum. Steel tanks offer excellent durability and are generally more affordable, but they are heavier and prone to rust without powder coating. Aluminum tanks are lightweight, corrosion-resistant, and ideal for marine use but can come at a premium price.
Valve Type and Safety Features
Look for tanks with an Overfill Prevention Device (OPD) valve or Type 1 valve, as these meet safety regulations in most states. These valves help prevent overfilling and leaks. Additionally, some tanks include built-in gas gauges to monitor propane levels, which adds convenience and prevents running out of fuel unexpectedly.
Tank Orientation and Size
Vertical tanks are standard and easy to store and replace, suitable for grills and standard propane-powered equipment. Horizontal tanks have a lower profile and are better suited for applications like fire pits, patio heaters, and RV use where space or aesthetic considerations exist.
Corrosion Resistance and Finish
A powder-coated finish on steel tanks helps prevent rust and weather damage. Aluminum tanks inherently resist rust and saltwater corrosion. If you plan to use the tank outdoors or in marine settings, consider corrosion resistance as a key factor for longevity.
Portability and Handles
Comfortable, built-in handles or collar designs improve ease of carrying and reduce handling risks. Some tanks offer molded handles without sharp edges for added user protection.
Certification and Testing
Ensure the tank is DOT approved and has undergone rigorous safety testing such as X-ray and hydrostatic tests. These certifications ensure the tank can safely withstand typical operating pressures and conditions.
