Helium Cylinders
Gas Cylinder Source offers a broad selection of DOT-certified helium cylinders designed for professional and commercial use across balloon inflation, party and event services, laboratories, leak detection, manufacturing, and specialty industrial applications. This category includes helium tanks in multiple sizes, from smaller portable cylinders to high-capacity steel and aluminum helium cylinders intended for higher-volume usage.

All helium cylinders sold by Gas Cylinder Source are manufactured or recertified to current DOT standards and equipped with CGA-580 valves, the standard outlet for helium and other inert gases in the United States. These cylinders are suitable for pure helium service and are compatible with standard helium regulators, balloon inflation kits, and industrial equipment.
Gas Cylinder Source sells helium cylinders outright, allowing customers to avoid recurring rental fees charged by traditional gas suppliers. This ownership model is ideal for event companies, balloon decorators, laboratories, universities, and industrial users who require reliable access to helium, predictable costs, and local refill flexibility.
Helium is a non-flammable, inert gas commonly used where lift, low density, or non-reactivity is required. Choosing the right helium cylinder depends on capacity needs, portability, frequency of use, and regulator compatibility. All cylinders ship empty for safety and regulatory compliance and must be filled by a qualified helium supplier before use.
For shielding during welding or just filling balloons, our selection of helium cylinders fits the bill.
All helium cylinders – 20 cu ft and 40 cu ft steel helium cylinders, and 22 cu ft and 60 cu ft aluminum helium cylinders – are ready to go for helium and other inert gas service, with CGA580 inert gas valves installed.
FREQUENTLY ASKED QUESTIONS
What are helium cylinders used for?
Helium cylinders are used to store and supply helium gas for balloon inflation, laboratories, leak detection, and industrial applications.
Helium is commonly used for inflating balloons due to its low density and lifting properties. It is also widely used in scientific, medical, and industrial environments where a non-reactive gas is required.
The cylinders in this category are designed for professional helium service and support a wide range of commercial and technical use cases.
Do helium cylinders ship full or empty?
All helium cylinders ship empty.
Shipping filled high-pressure helium cylinders is restricted for safety and regulatory reasons. Gas Cylinder Source ships cylinders empty so they can be transported legally and safely nationwide.
Customers must arrange filling with a qualified helium supplier that supports the cylinder’s pressure rating and valve type.
What sizes of helium cylinders are available?
Helium cylinders are available in a range of sizes, from small portable tanks to large high-capacity industrial cylinders.
Smaller helium tanks are commonly used for balloon inflation and event work. Larger cylinders are preferred by laboratories, universities, and industrial users to reduce refill frequency.
Selecting the correct size depends on usage volume, handling requirements, and available storage space.
Are these helium cylinders DOT certified?
Yes, all helium cylinders sold by Gas Cylinder Source meet current DOT certification requirements.
DOT certification ensures the cylinder complies with federal standards for construction, pressure containment, testing, and identification. This is required for legal transport and filling in the United States.
Cylinders are either newly manufactured or recently recertified, providing current test dates and long-term service life.
What valve type do helium cylinders use?
Helium cylinders use CGA-580 valves.
CGA-580 is the standard valve outlet for helium, argon, nitrogen, and other inert gases in industrial and commercial applications. This standard helps prevent incorrect gas connections.
Most helium regulators and balloon inflation kits are designed for CGA-580 compatibility.
Can helium cylinders be used for balloon inflation?
Yes, helium cylinders are commonly used to inflate balloons.
They can be paired with balloon regulators or inflation nozzles to control gas flow and prevent balloon damage. Cylinder size determines how many balloons can be inflated before refilling is required.
Event professionals often choose larger cylinders to support high-volume balloon work without interruption.
What is the difference between steel and aluminum helium cylinders?
Steel helium cylinders are heavier and more economical, while aluminum helium cylinders are lighter and corrosion-resistant.
Steel cylinders are often used in stationary or high-volume environments where weight is less of a concern. Aluminum cylinders are preferred for portable and event-based applications due to their ease of handling.
Both materials meet the same DOT standards and are suitable for helium service.
How much pressure do helium cylinders hold?
Most industrial helium cylinders are rated for service pressures around 2,200 PSI.
The exact pressure rating is stamped on the cylinder and must be matched with a compatible regulator. Larger cylinders hold more helium because of their greater internal volume, not because of higher pressure.
Users should always confirm pressure ratings and regulator compatibility before filling or using.
How often do helium cylinders need to be recertified?
Most steel helium cylinders require recertification every 10 years, while most aluminum helium cylinders require it every 5 years.
The current test or requalification date is stamped on the cylinder shoulder. Cylinders that are out of test are not compliant and may be refused by filling stations.
Regular recertification ensures continued safe operation under high pressure.
Who should buy helium cylinders from Gas Cylinder Source?
Helium cylinders from Gas Cylinder Source are ideal for event companies, balloon decorators, laboratories, schools, and industrial users who want to own their cylinders.
They are well-suited for organizations that use helium regularly and want compliant, professional-grade equipment without rental contracts.
Gas Cylinder Source supports both single-cylinder purchases and bulk orders, making this category suitable for small businesses and large organizations alike.
