Video Transcript for Valterra RV Sewer - Connectors and Fittings - F02-2103 Review

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.

as always good product and good service

worked perfect
Jerry - 11/17/2022


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.

No leaks no problems.
Bruce - 01/15/2022


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


Just what I needed for the restricted area that I had to work in!


Just what I need to fix a leaky tank co nnection.


Worked great so far


Seemed to be an exact replacement of the part that dry rotted after 5 years. Hopefully no more drip drip drip of the nasty stuff under the camper going forward.


Perfect fit less tab 10 minute install


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.


fits just like original equipment


I liked how you kept me informed the whole time and the parts where delivered on time. Thank you. William Great job.


Worked Great , Solved My Problems !!


after xmas to easter trailer build, very happy with everything i got from etrailer, inside and outside showers, 2nd toilet, 2nd cook and cleanup area, out of the weather garage for utv and motorcycle, added freezer to our travels, running off solar, still alot of work ahead, not done with you guys yet, thanks for your great resource!


Thanks so much for the coupler for the rigid RV waste pipe. You were the only folks that had exactly what I needed ! Also the price was great and shipping was really reasonable. Keep up the good work and I will surely be a repeat customer. Thanks again . Mike


Good Price. Good quality


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


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.


It fits perfectly and I have not had one issue with it whatsoever, I wish I had come to first. I know I will on the future.


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.


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.


All items as described.


The product I ordered from e trailer was exactly what I wanted and also was delivered a day early thanks for your excellent service.


Quality item, easy to replace.


I was very pleased. E-Trailer had most of the items I needed to make a repair on my self contained camper. The order came in as expected and on time.


Received as listed

  • Is Lubrication Needed When Installing Valterra Coupling for Rigid RV Sewer Pipe # F02-2103
    You are not required to use any lubrication when installing the Valterra Coupling for Rigid RV Sewer Pipe # F02-2103 that you referenced. You'd just need to slip it over the ends of the pipe and then tighten the band clamps and you'd be set!

  • Picking Out Replacement Rubber Grommet for RV Black Water Tanks
    That's a good question but we don't have a way to look that up since Winnebago does not list that as a spec anywhere. You'd have to measure and verify before ordering either the 3 inch # F02-2106 or the larger size # F02-2103. Since the 3 inch size is the most common one there's a very likely possibility that's the size you need.

  • Rubber Grommet Connector Between Black Water Tanks and Waste Valve.
    This is an unexpected configutation with the valve connected directly to the black tank. Nevertheless, it seems that a Valtera # F02-2106 Replacement Rubber Grommet would fix you right up. I think I would spring for some new Valterra # H03-0018 hose clamps. If you find that you have 3-1/2" connections (rather than 3") then the Valterra # F02-2103 coupler will be needed. Otherwise you will be ready for the Valterra # T18A waste valve.

  • How to Fix a Tear in Sewer Hose for RV
    The Valterra Flexible Sewer Coupler # F02-2103 that you mentioned is designed to convert from a flexible drain hose to a rigid pipe connection. What you will want to use is the Straight Drain Hose Coupler # F02-2025BK to connect the two ends of your 3 inch hose and the Stainless Steel Hose Clamps # H03-0009 so secure the hoses to the coupler. Valterra also has a hose kit that they call the Dominator, pert # D04-0275, which features 20 feet of sewer hose that can collapse to 39 inches...

  • Replacing The Double RV Waste Valve On Your RV Or Camper
    When installing the # 34466NDHR19AAA you can use a nipple like # T3524 and connect it to your the waste valve with some ABS cement # A05-0303 and then a # F02-2103 coupler onto the tank pipe.
