You will want to contact your supplier to verify which regulator you need for the tank you will purchase.

This works well with ozone therapy that requires low flows of oxygen. It is usable in any condition due to the fitting being made of solid brass. It comes with a one year warranty.

Important Notes (all users)

The maximum pressure allowed in these regulators is 2600 psi. Many countries in Europe, Australia and a few others will typically fill beyond that (3000+ psi). You will need to discuss this with the oxygen tank supplier to ensure the pressure is well below the max limit to ensure the regulator isn’t compromised and no longer usable. Promolife is not responsible if the regulator is used with a higher pressure and damaged. A new regulator would have to be purchased.
