The argon supply line on my welder is 1/8″ O.D. tubing. I purchased a regulator that has a barb supplied, but the barb is for a 1/4″ O.D. line. How do I connect the small line to my regulator?

If the regulator and barb were Forney products, we do have an adapter, ITEM# 85359 that will work for the connection. It’s a quick connect device that the gas line goes inside of. To order this product, you’ll need to contact our Customer Service team.
