Which supply method suits you best?
Besides the options above, two more points will help you choose correctly:
- New cylinder vs. ordinary full cylinder: if you are buying a cylinder for the first time or have a long-term project, a brand-new sealed cylinder (not just a filled one) is the safer choice.
- Cylinder exchange vs. refilling: for customers with continuous consumption (industries and hospitals) who don’t want production to stop, exchanging an empty cylinder for a full one is faster than waiting for the same cylinder to be refilled.
All oxygen cylinders are checked before delivery for appearance, valve condition and technical specifications, and the hydrostatic test is carried out free of charge.

Quality, standards and supply guarantee
A stable, high-quality supply of oxygen cylinders is as important as the product itself, especially for customers with continuous consumption such as factories, hospitals and petrochemical companies. Every cylinder is checked before delivery for the condition of the body and valve and compliance with ISO 9809, and the hydrostatic test is carried out free of charge. For wholesale orders and customers who need continuous supply (factories, hospitals, tender companies), a periodic supply contract can be discussed on request. At every stage of the purchase, our sales team is available to advise and help you choose the right volume or type.
Required accessories
The following equipment is needed for the safe use of an oxygen cylinder:
Flowmeter: controls and displays the outlet flow rate
Pressure gauge: shows the pressure inside the cylinder and the outlet pressure
Regulator: sets the outlet pressure to match the user’s needs
Cylinder pallet: for safely moving and storing several cylinders at once, suitable for wholesale orders and factories
Cylinder valve and cap: available both pre-installed on the cylinder and separately for replacement
You can see full specifications and buy this equipment on the cylinder accessories and welding and cutting equipment page.
When buying a cylinder, be sure to check the hydrostatic test date, the standard gas color, the valve type (CGA), the body material, a working pressure of at least 150 bar, and that there is no damage or rust.
All cylinders are made to ISO 9809 and checked before delivery for the condition of the body, the valve and the hydrostatic test date; this test is carried out free of charge.
Yes. For wholesale orders and customers with continuous consumption, a regular delivery schedule and special terms can be arranged; the 50-liter size can also be supplied to order this way. Contact our sales team to discuss your needs.
The main difference is the purity grade and the permitted use. Industrial cylinders are used for welding and cutting, medical cylinders must have a specified purity and be used under the supervision of medical centers, and laboratory cylinders provide the highest purity for sensitive applications. The three types can be told apart by their colors (white for medical/laboratory, black for industrial).
