FREQUENTLY ASKED QUESTIONS
What are propane cylinders used for?
Propane cylinders are used to store and supply propane gas for heating, cooking, equipment operation, and industrial fuel applications.
Propane is commonly used in commercial kitchens, forklifts, construction equipment, space heaters, and agricultural operations. Its portability and high energy output make it suitable for both indoor and outdoor professional use.
The cylinders in this category are designed for regulated propane service and are compatible with standard propane regulators and appliances.
Do propane cylinders ship full or empty?
All propane cylinders ship empty.
Shipping filled propane cylinders is restricted due to safety and transportation regulations. Gas Cylinder Source ships cylinders empty so they can be transported legally and safely nationwide.
Customers must arrange filling with a qualified propane supplier before placing the cylinder into service.
Are these propane cylinders DOT certified?
Yes, all propane cylinders sold by Gas Cylinder Source meet current DOT certification requirements.
DOT certification confirms compliance with federal standards for construction, pressure containment, testing, and identification. This certification is required for legal transport and refilling in the United States.
Cylinders are either newly manufactured or recently recertified, with current test dates and a reliable service life.
What valve types are used on propane cylinders?
Propane is stored as a liquid under pressure inside the cylinder.
As propane is drawn from the cylinder, it vaporizes into a gas for use by connected equipment. Cylinder pressure varies with temperature rather than remaining constant.
Proper storage and handling are critical to safe propane operation.
What sizes of propane cylinders are available?
Propane cylinders are available in a wide range of sizes, from small portable tanks to large-capacity industrial cylinders.
Smaller cylinders are commonly used for cooking equipment, heaters, and mobile applications. Larger cylinders support forklifts, warehouses, and continuous-use operations.
Selecting the correct size depends on fuel consumption rate, runtime requirements, and storage space.
How often do propane cylinders need to be recertified?
Propane cylinders require recertification at intervals defined by DOT regulations.
The current test or requalification date is stamped on the cylinder collar. Cylinders that are out of test are not compliant and may be refused by propane filling stations.
Regular recertification ensures the continued safe storage of liquefied propane gas.
Can propane cylinders be used indoors?
Propane cylinders can be used indoors only when permitted by local codes and when connected to approved indoor-rated equipment.
Many indoor propane applications require specific ventilation, cylinder size limits, and safety controls. These requirements vary by jurisdiction.
Users should always follow local fire codes and equipment manufacturer guidelines.
Why buy propane cylinders instead of renting them?
Buying propane cylinders eliminates recurring rental fees and provides long-term cost control.
Rental programs can become costly over time, especially for businesses operating multiple cylinders. Ownership allows organizations to manage inventory, refills, and maintenance independently.
Purchased cylinders can be filled locally without distributor-imposed contracts.
