Oxygen Tank Regulator Adapters for British and European Tanks

These adapters will allow you to connect our 540 low flow oxygen regulator to British or European oxygen tanks.

Are you using British or European style oxygen tanks and are unable to use a pediatric low flow regulator  designed for ozone therapy? These adapters will allow you to use our low flow regulator with your tank.

There are two types available. The British adapter will allow you to connect a low flow regulator to a BS 341-3 tank with a 5/8" right hand internal thread. Countries that currently use these tanks include Australia, the United Kingdom and a handful of European countries. If you plan to use a 540 regulator, you may be interested in the 540 regulator with built in adapter.

The European adapter will allow you to connect a low flow regulator to a DIN-477#9 (German Institute for Standardization sizing) with a tank valve thread size of 26.4mm.

The picture below shows sizing specifications.

If you need:

• CGA-540 USA to BS 341-3 oxygen tank, choose the British adapter above.
• CGA-540 USA to DIN-477#9 oxygen tank, choose the European adapter above.

Please note there are other tank sizes that don't match these specifications. These adapters will work for tanks that have the specifications listed here.
