Air Dryer?

[everlastsupport]

Cheap HF desiccant dryer after the regulator/filter, but before the gas inlet. It has 1/4" MIP/FIP fittings so you can rig it up with a quick disconnect to make it easy to pull out of the line. The filter has an internal thread, so you can disassemble it to replace the desiccant when it has expired.

I use these as well, just pitch them when done. Get them on sales for $4.00 each. I have heard of people baking them back to blue color. When pink they are done.
