Not all made
The ring with the catches on it very easily comes loose from the outer ring. In other words, the part the fastens to the RV sewer hookup is glued to the pipe. This joint is extremely easy to break loose and at that point the fittng is junk. Tried 3 and they all broke. Camco needs to rethink they are gluing the two parts of this firing together.

Thin, weak plastic.
I could hear the plastic start to break when I was installing the male treaded end of this adapter into the female threaded end of a Charlotte Pipe 3” DWV female PVC adapter. I wrapped the male threaded end in teflon tape and as I was tightening the connection by hand, I heard the plastic on this piece start to crack. This fitting needs to be the same thickness as 3” PVC pipe.

Inside gasket will LEAK, to thin.
Cheap, Cheap thin gasket, LEAKS. Don't waste your money on this cheaply thin gasket, inside the collar. Camco needs to have China install thicker made gaskets instead of getting greedy. Gasket is totally the weak link in this product. Have you noticed all China made products have a weak link that always fail early so Americans can keep the economy going and make Camco lots of money as nothing last very long. Did not have to return it to get my money back. Camco knows it is defective.

Works as it says
The only problem is that the two pieces separated where they were glued. Unable to use this anymore

Worked great with 3” Fernco
I purchased this item to “hard plumb” my RV to 4” thin wall PVC sewer line. I ran 4” PVC sewer line all the way to the RV drain, used a 4” elbow, used a 4” to 3” thin wall reducer and connected this fitting to the 4 to 3 reducer with a 3” to 3” Fernco flex coupling. The Fernco allowed the fitting to be mounted to the RV (twisted to lock on), then I slid the Fernco Coupling onto this adapter and tighten the clamp. Worked perfectly!! I am recommending this to my friends.

The wall thickness on this is TOUGH.
Did the job for my E-pro 19 footer. Have a high end sewer hose , but the dump end is a PIA as it has hooks and not post - so this was the fix. Ken

Stay away from these.........
These are horrible for there attended purpose. They only have 2 hooks and the rubber gasket is not thick enough to give a good seal. I bought 2 to hard plumb my trailer on my seasonal lot because I didnt want to cut the tabs off my connections incase I wanted to travel at some point. Wish I would have seen the other reviews before I bought. From looking at the picture I thought they were made of steel and that 2 clips would be enough. Nope cheap plastic and after the 2nd dumping they are leaking. The other 4 clip ones on here would have been alot better. Atleast maybe then I wouldnt be afraid of the cheap plastic clips breaking off. Probably end up taking them off and just use the 3" to 3" rubber connectors. Oh well live and learn.
