Searching for Non-Corrosive Material Against Water & Oxygen

[Cadman5150]

Hello gentlemen -

New to the forum here! ... I have what I hope is an easy question for my Materials & Chemical buds.
Is there any material that is 100 percent non-corrosive against water and oxygen (sometimes nitrogen)? ... I work for a Gas Analytical company, whereas we test the permeability for different materials.
To do so, we run a mixture of water and oxygen (or nitrogen) through these units.

Not sure if I'm really explaining this well enough.
I'm basically looking for a material that will be non-corrosive, or a "treatment" that would satisfy the objective.

Any help would be so appreciated.

Mike

Welcome to PF.
Maybe Polyethylene. PE powder coated.
You give chemical properties, but what physical characteristics must the material have?

Thanks Baluncore - the material would most likely be Aluminum (6061 or sim.)
