The premium RhinoFLEX RV sewer hose kit is just right for most travel trailer applications. It features a tough 15-foot tough 23mil polyolefin hose reinforced with steel wire. It also includes swivel lug and swivel bayonet fittings, a translucent elbow, and a 4-in-1 campground end fitting. At the trailer end of the hose, there is a super-tough bayonet fitting with 4 bayonets for a more secure fit on all modern Valterra size nubs. At the dump-station end they've added a translucent elbow that disconnects from the 4-in-1 adapter for easy storage. It's a ready-to-use kit made with the toughest hose you can buy. Pre-attached fittings feature locking rings so your fittings stay secured. Bayonet cap and elbow cap also included.
