Pipe and Hose Reducer, 4" to 1.3125"

This fitting is made to fit a 4" duct to a 1.3125 (1 5/16") vacuum hose. The large end has a lip slightly over 4 inches and is slightly under 4" on the inside so it will sit flush without falling in. I used tape to finish the seal on this one. The small end has an interior fillet to make for smoother fluid flow and fits inside a common hose.
