Camco 39857 RhinoFLEX Clear 90 Degree RV Sewer Hose Swivel Fitting - Heavy Duty Waste Water Connector for Campers, Trailers & Motorhomes

Like being able to see in the pipe and attach a hose from the outside. It did leak with the sewer hose attachment tho.Good quality, can see when waste gets clearSwivels and seals goodItem as describedComes in handy when dumping rv tanks easy to see if the water is flushing clear. Also comes in handy when hooking up to awkward rv park hookupsThe right angle I was looking forWhile not the most glamours part of camping probably one of the most necessary parts. Fit great, no leaks and let you see when your tank was “clear” (let’s be honest once you get fairly cloudy water the tank is “clean”) grips in all the right spots and easy to work withI use it to connect the rear tanks on my RV to the septic hoseI use a macerator pump and I do not want the pump to go dry, so with clear 45 Deg Sewer Fitting I can shut if off safely./Does what i needed and makes pump out easier being able to see what is getting stuck or notVery good clear visual pointMy wife asked me why we needed this but after I showed her the benefit of using it - she thought every trailer should have one.There are two benefits to this 45 degree sewer coupling.1 - The tank outlets on our trailer are fairly low to the ground making it difficult to dump the tanks sometimes depending on the ground terrain. The 45 degree bend creates additional clearance but is not to sharp a bend as to impede the flow of liquid from the holding tanks.2 - While I purchased this adapter mainly for the 45 degree elbow the most beneficial feature is the Clear window which allows you to view the progress and contents of your holding tank while you're dumping it. No more guessing if you're black tank waste is sufficiently broken down and your tank treatment is working. You can view the sludge as it passes through the clear window. Likewise seeing the quality of the water when emptying the grey tank is equally beneficial. If you see a large debris item you don't have to guess "What plugged my hose" or "Why is the flow of my hose so slow". The clear viewing window is also great for rinsing your tanks and lets you know when your tanks and house is sufficiently flushed clean.All in All this 45 degree adapter is very useful. Once you try it, you won't want to empty your tanks without it.I would recommend this adapter to any RV owner especially for the Clear viewing window.Absolute junk! I bought this in the fall for the next years camping season and the first time I used it with the brand new rhinoflex hose I also bought this elbow leaked like crazy. I stretched my hose and used it with out this elbow there were no leaks. After googling it I have found many others with the same issue on the elbows. And there are orings in place. If I didn’t have my black water tank leaking all over I would have taken a pic!This product is great for viewing the wastewater as it is emptying. (recommended) for all RVers! The 45’ bend, softened the flow into our drain hose.+ I’m afraid to inform potential buyers that ours leaks also. (The rubber seal needs to be a little thicker.) I will try a small application of silicone under the rubber and let it set up to increase the thickness a little. WILL LET YOU KNOW IF IT HELPS?
