The orange picture above is 3/8" internal bore so a bit too big in diameter for the OP's needs but you can get it in smaller bore sizes say 3/16" or 1/4"
The orange colour shows that the core of the tube is non conductive so we use it only for long runs of HP oxygen. For reference the length in the picture is 50 Mtrs 165 foot on the left and a 30 metre length 100 foot on the right.
The Green colour in the 3rd photo below is 1/4" bore and it looks nice and pretty.
Some folk mistake the green colour we use as being for Nitrox.
By explanation the wall heater in the picture is a 2kW heater its a British thing you would'nt understand. Just think of it as an air conditioning cooler unit.
