Camco's Rhino X is an all-inclusive, maximum compression RV sewer hose kit that provides the ultimate compact storage. The Rhino X compresses more than any other RV sewer hose to open up valuable storage space. This 20-foot kit provides the equipment you need for a quick, reliable sewer hookup. It includes: (2) 10-foot heavy-duty 23mil polymer RV black water hoses, (2) pre-attached swivel bayonet fittings, (1) pre-attached swivel lug fitting, (1) pre-attached swivel transparent elbow with 4-in-1 adapter, and (4) RV sewer caps. The sewer hose is designed to hold its shape and stay in-place during use. The included 4-in-1 adapter is compatible with a 3-inch slip or 3-inch, 3 ½-inch, and 4-inch NPT threaded sewer connection. The transparent elbow allows you to see when your tank is empty. RV sewer hose fittings swivel 360° for simple connecting. Once the 4-in-1 adapter is removed, the RV sewer hose fits in 4-inch square bumpers. The hose and fittings compress to approximately 31-inches. This accessory is an RV must-have. It’s great for motorhomes, travel trailers, 5th wheels, and more.
