| 80 cu ft Steel Oxygen Cylinder | Oxygen | 80 cu ft | Medium-duty shop use, portable yet steady |
| 20 cu ft Cylinder for Oxygen | Oxygen | 20 cu ft | Lightweight, portable jobs |
| New 145 Cu Ft Steel Acetylene Cylinder | Acetylene | 145 cu ft | Heavy-duty cutting and brazing |
| Hobart 770270 Oxy/Acet Cart Bottle | Oxygen & Acetylene Cart Bottle | Cart bottle | On-site mobility and transport |
The following table summarizes key attributes to compare quickly. It focuses on capacity, typical use cases, and handling considerations to help you choose the right bottle for your workflow.
125 Cu Ft Oxygen Cylinder For Demanding Jobs

Best for: High-volume professional operations that require extended oxygen supply. The large-capacity steel cylinder features a CGA540 valve and a robust steel construction. It is DOT approved for safe transport and storage. This makes it well-suited for industrial welding, metal cutting, and medical-related oxygen supply when appropriate. Caution: Ensure regulators and equipment are compatible with CGA540 and oxygen service only. The heavy tare weight and size demand proper handling equipment.
80 Cu Ft Oxygen Cylinder With Valve

Best for: Shops and healthcare settings needing a balance of capacity and portability. This cylinder uses a CGA540 oxygen valve and a 2015 PSI service pressure. It is green-graded for oxygen with a protective collar. Caution: Not compatible with other gases; verify regulator compatibility before use. Better for frequent refills in mid-sized operations than the smallest bottles.
20 Cu Ft Oxygen Cylinder (Free Shipping)

Best for: Lightweight projects and on-site repairs where easy transport matters. This cylinder ships empty and includes a CGA-540 valve for oxygen use. It comes with a hydrostatic test history noted as 10-year. Caution: It ships empty; you will need to fill it before use and ensure compatibility with your gas supply and regulators.
New 145 Cu Ft Acetylene Cylinder

Best for: Heavy-duty cutting and brazing tasks that require long run times between recharges. The DOT-8Al/TC-9WAM stamped cylinder uses a CGA510 valve. Caution: Acetylene stability requires proper storage and ventilation; avoid exposing to high heat. Choose this when processing thick metals for extended periods.
Hobart 770270 Oxy/Acet Cart Bottle

Best for: Mobile welding teams and shops needing a transport solution for both oxygen and acetylene. The cart bottle helps with on-site deliveries and job-site transitions. Caution: It is a cart setup, which requires space and proper handling to avoid tipping. Consider pairing with compatible regulators and hoses for safe operation.
Buying Guide
What capacity do I need?
- High-volume work benefits from larger capacities like 125 cu ft or 145 cu ft. For frequent refills or portable jobs, smaller bottles such as 20 cu ft offer easier transport.
Which valve and compatibility matter?
- CGA540 is the standard oxygen valve connection; ensure regulators and hoses match. Acetylene uses its own standards; verify CGA510 compatibility for acetylene tanks.
Where will I store and transport the bottles?
- DOT approvals indicate safe transport. For mobility, consider carts or stands designed for oxygen or acetylene bottles. Ensure good ventilation when using gases like acetylene and stable mounting for storage at the workspace.
Safety and handling tips
- Keep cylinders upright and secured. Use proper caps and collars for valve protection. Do not mix gases in incompatible devices. Handle with care to prevent impact damage and leaks.
What combination is practical for a shop?
- A combination of a larger bottle for constant use (125 cu ft or 80 cu ft) plus smaller portable bottles (20 cu ft) can balance run-time with transport.
FAQ
- Are oxygen and acetylene bottles interchangeable?
- No. They require different regulators, hoses, and safety practices. Use only compatible equipment with each gas.
- What is CGA540 used for?
- It is the oxygen-specific valve connection. Ensure regulators match CGA540 for oxygen service.
- How do I transport large cylinders safely?
- Use a proper cylinder cart or stand and secure the bottle to prevent tipping during transport.
- Can I store acetylene indoors?
- Yes, in well-ventilated areas away from heat sources and flames. Follow local safety guidelines for storage of acetylene.
