It transitions a 4-inch pipe down to a 3-inch pipe while keeping one side flat, which prevents product pooling in horizontal runs on tank trailers. Commonly used in crude, dry bulk, gas, or petroleum trailer piping systems. Replace it when the aluminum is cracked, corroded, or when reconfiguring product lines.
