DIY Cooler - What fittings to use?

[martinnman]

Check your freon levels if your cooler is not providing you with cold water any longer. If it appears that there is a problem with Freon, you need a professional to fill the freon. Only those with appropriate certifications are legally licensed to handle freon.

Martinnman,

I think they are talking water coolers for a TIG torch, not a refrigerated air dryer for plasma.
