The water discharge hose is designed for moderate discharge service. The hose is a strong, light-weight and flexible hose for construction site service. Our discharge hoses lay flat when not in use. This makes handling the hose and moving around the work site much easier. We offer these hoses in 2", 3" and 4" fittings. These fittings will fit all of the Koshin pumps we carry. Paired with a Koshin pump and a suction hose, you will have everything needed to get most jobs done. These hoses work great with our Koshin pumps and help make your job a little bit easier. These hoses are very durable and work in many different situations.
