Known as the toughest RV sewer hose on the market, Camco's RhinoFLEX sewer hose gets even better with this RhinoFLEX extension kit. This kit includes everything you need for quick, dependable hook-ups: a 5' RhinoFLEX extension hose, made of 23 mil heavy-duty polyolefin that extends, compresses, and bends without losing its shape; and pre-attached swivel lug and bayonet fittings that may be moved between RhinoFLEX hoses.
