Cobblestone Pipes are used for transporting items. They will connect to all other pipes except they will not connect to Stone Pipes or Advanced Insertion Pipes. When used with Gold pipes, the rate at which an item travels through Cobblestone Pipes decreases faster than with Stone Pipes. Cobblestone Pipes can be Waterproofed.
