Works as advertised. The 4" clear Woodstock hose fits easily but snugly and is easily tightened with zip ties. Sturdy enough as once in place it won't take the shock of being connected to a flexible hose. Everything I ordered had a ridge where the Y fits on the straight section. Easily removed by drilling along the seam in several places with a 1/8 bit, chipping off excess with pliers and deburring with a coarse half-round file. Takes 1- 2 minutes for each Y-shape fit. I doubt this price can be beat at $6.30 with free shipping and I looked around.
