Sulphur dioxide

[golddie]

I will be going to grainger soon and I would like to buy a coupling for my Sulphur dioxide gas tank.
I tried to find this on their site but I couldn't I am sure that if I go there they will be able to help me however I would prefer to go there with the item number so that I will be better informed about this product.
So I will need a coupling with a valve and a clasp to attach a hose to it and this should be stainless steel and as for the tube any tube for gas will probably work.
I typed in word like valves and other similar things in the search feature but no help

I searched CGA fittings. (Compressed Gas Association)

From the chart you need CGA 660. However where you buy your SO2 may be a better place to look for the fitting, Granger's stock regulators with CGA 660 connections but online no individual fitting.

Thanks for that link
I guess when I go there and tell the Sulfur dioxide and mention 660 they will understand

you also need a stainless steel tube to attach to the hose.

you also need a stainless steel tube to attach to the hose.

I'm not sure why. You certainly don't want to use stainless when precipitating gold. Glass tubing is a requirement.
