Refill or exchange your gas cylinder: send us the empty one and get it back full, or swap it for a full cylinder of the same size and gas – for CO2, N2O, argon and welding mixes, from 2 kg to 50 L.

Two ways to a full cylinder
- Exchange – for cylinders you bought from us: send the empty one and get a full one of the same size and gas back. You need the order number of your cylinder purchase.
- Refill your own cylinder – we fill your cylinder and return it. It needs a valid test date and a valve for the gas.
Small cylinders: 2 kg, 3.75 kg, 5 L
Order the refill for your cylinder size and gas; we send you a shipping label for the empty cylinder, check it on arrival and send it back full.
Industrial cylinders: 8 to 50 L
Choose the gas filling of your gas, then exchange or refill and your cylinder size. No cylinder of your own yet? Buy it once – no rent, no deposit – under argon, welding gas mixes or CO2. Step by step, and how large cylinders reach us: how refilling works.
