FERNCO the standard for rubber dwv couplings
i was a purchasing agent for a plumbing supply . these FERNCO couplings were essential for DWV installations . we were constantly reordering . there are other rubberized couplings out there but FERNCO is the best and the ones the plumbing trade uses . the price here is fair …

Perfect for RV connections
This is the second one that I've purchased for my connection to my camper tank. Works well and keeps you from having to have a coupling and/or glue. It is sometimes a little tight and requires some coaxing or lubrication to get it to slide over the fittings especially in cold weather.

It's a decent flex coupling
The reason for the 4 stars is that I had to ask for a refund because it came with only one clamp. Obviously it was suppose to have two (just like the pic) and from the looks of the coupling it had one on there at one time because you can still see the imprint that it left. It was not in the box and It was a decent coupling but they didn't send it complete. I could have gone to the big box store for it but It was the convenience of being able to order online. These things happen!

Heavy duty and robust!
Heavy duty rubber coupling and tough band clamps. Great value!

Perfect fit for ABS pipe
This fits my 3" ABS drain pipe perfectly. Many rubber sleeves require major wrestling and strength to get them over the pipe, but this slides easily with just a little twisting. I added grease to be sure it comes off again when necessary, but I probably didn't have to. It was around 60 degrees F when I installed it. The grooves in the rubber for the clamps is another great feature for ease of installation in tight areas.
