The Camco RhinoFLEX 45-Degree Hose Fitting swivels and snaps easily into place for quick installation onto your RV sewer hose. The tube's lug and bayonet fitting create a solid seal to ensure no leakage during maintenance. The RV sewer hose fitting's soft, 45-degree angle eases hose strain and provides contents a gentler impact as the tank is being emptied. It is composed of clear UV-stabilized resin to ensure long life. The transparent materials also let you monitor drainage progress.
