Today we're going to be taking a look at the Valterra Flexible Sewer Coupler. This is used to covert from an RV flexible drain hose system to a rigid pipe connection to the sewer. It includes the hose clamps, one at each end for easy security. It's going to couple standard three inch, schedule 40 ABS pipe. A few measurements to go over with you real quick. Inner diameter, it's going to measure three and a half inches.
External diameter, about four and one eighth. That's going to be the same on each side. You see you got the nice metal hose clamps, very easy to use. Tighten those down using a flat blade screwdriver or a small socket. Measuring edge to edge going this direction, we're looking at about two and one quarter inches.
That's going to do it for today's look at the Valterra Flexible Sewer Coupler.

This the best sewer fitting that I have ever bought. Thanks for asking!
Just what I needed for the restricted area that I had to work in!

The coupler has been in place for one year and has not leaked. I am very happy with this product.
1st rate service!
ordering was really easy and came on ti me
Works as designed. Helps with slightly offset sewer pipes.
etrailer has always been fast, good customer service, great selection of parts, easy to deal with....
This was a great replacement for my 2009 Winnebago Access! Perfect fit!
Product was exactly as described. Appears to be good quality and it fit on my 2017 Travato 59K. Haven’t checked to see if it leaks, if it does, Im sure it will because of installer, me. Actually arrived 3 days earlier than expected.
Fast reliable shipping.always great customer service . The product was an oem replacement on a 2011 Winnebago View. It fit perfectly.
I used etrailer rather than the huge seller because if I need technical assistance etrailer is the best.

worked perfect
They were a perfect fit
As I had hoped, the T80A was the exact replacement for the waste valve on my 2006 motorhome. Removal of the old valve and installation of the new took me about three hours.
This product went on easily and i can see why you just dont buy a hardware store coupler. with a ridge in the middle it should stay on the outlet and drain even if it gets loose
This made installation of a new waste valve much easier IMO. I was careful to clean road grime and lightly sand some undercoat overspray off the old pipe to avoid any chance of a leak.
It fits perfectly and I have not had one issue with it whatsoever, I wish I had come to etrailer.com first. I know I will on the future.
Got just what I needed. I was looking for some way to connect my RV to a 30 ft length of 3 inch PVC. Flex live was far to difficult to handle.
Thanks for your support
Fast, correct, great customer service and terrific follow-up. If you can do the work on your RV yourself, etrailer is the place to get your parts. I appreciate the service they provided me.
The original couplets on our 12 year old motorhome rotted and started to leak. These are the identical replacements and look good and I received them quickly.
This coupler was a good replacement for the rotten original. I used it to connect the grey tank outlet to a section of solid pipe.
The product I ordered from e trailer was exactly what I wanted and also was delivered a day early thanks for your excellent service.
Quick delivery!!
