Audi A4 B7 Catch Can: Nipple Plug
When I bought the catch can for my b7, it came with two nipples. Instead of looking for a fitting to plug the second outlet, I decided to cut off the nipple and plug it with a piece of stock. A little lathe facing to clean it up and voila, we are down to one outlet.
This previous post shows the install of the catch can.
