Today we're going to be taking a look at the Valterra RV Sewer Slip Hub with Flange. The unit's made from a durable black plastic construction. The slip area is for a 2" piping, so that's going to give us an inner diameter measurement of 2 3/8", outer diameter measurement of 2 3/4". This side right here would butt up to something like a valve or something that has the correct mounting options for the flange side of the fitting. The mount holes on the unit are separated on center by 2 7/8". It's a square design so it's going to be the same between each hole.
Edge to edge it measures about 3 3/8", that's a square design, that's going to be the same measurement for each side. That's going to do it for today's look at the Valterra RV Sewer Slip Hub with Flange.

Everything looks great. Great customer service and timely shipping. I will be shopping at etrailer.com for all my camper needs. Thanks again.
I had broke two on my camper in transport. Tried to find these everywhere. No other site or plumbing specialities had these e trailer was the ONLY place I could find them. So after several days of searching I finally bought them through e trailer. I had them within 3 days and installed just as soon as I got them
If you have an issue about RV repairs, or tow vehicle and your RV-E-Trailer will have an answer that will send you in right direction. They have a dedicated staff that knows the information you need and are super good with any concerns you might have. I've used them over the years for parts that are $100+ to a $1.80 part. Same results-Great!!
I almost never write reviews or take customer sat surveys. I'm making an exception this time due to the excellent service from Emily and George at etrailer.com. I ordered several products that were not in stock. I was kept informed of the status of my order and the items were shipped when they said they would be shipped. As for the products, they were exactly what I expected - quality items from Valterra.
Ok, not exactly a big purchase or something exciting. But... something I needed. etrailer is AWESOME. Half the value of the purchase was not the fact that shipping was near immediate, or the great customer service I've had in the past, or that the order was actually correct and got here when promised. That's all the other half! The first half was that they have great videos and write-ups explaining so many of the things offered in the site. In this case, I was a bit unsure if I needed 2" or 1.5", based on the while inside/outside diameter confusion. The info on the site answered that perfectly and the right parts arrived. Always happy to shop etrailer!
There is nothing glamorous about buying 3" DWV fittings. But, etrailer made it easy with their great website and helpful videos. Was able to order all the fittings I needed to install a Sani-Con on my fifth wheel.
Product was correct slip hub to replace fitting on a broken ABS pipe. Worked well.
Alex was very helpful. got my order expedited immediately. Great customer service. Thanks e trailer!!
I purchased a number of plumbing components for my class A motor home. It has been a year since they were installed and I have had no issues what so ever. I am very pleased with the quality of the plumbing components as well as the availability of a rather obscure piece I needed for the repair.
I will definitely use etrailer in the future.
Great product
Great price and exact OEM replacement for my repair. I spent hours searching for this flange. Now I know where to find my RV parts.
We ordered wrong size. Called etrailer and with guidance got correct part ordered!! Great products and company!
Tried to use as a substitute on my Bristol sewer manifold when original Bristol fitting broke when trying to remove grey valve. Will slip over 1-1/2" ABS pipe, but bolt holes do not match between brands. Threw away fitting (not worth my time & money to return) due to alignment issue and Bristol rubber seal not fitting with Valterra part.
Exactly what I wanted and it arrived qu ickly!
Beat other online retailer. Surprising.
This ítem is exactly what I'm looking for my custom work
I ordered this flange with the 1.5 flange because I wasnt sure of the size I needed. needless to say its the one that I dont need, but it came on time and the price was fair.
Product was received but wrong size was mistakenly ordered

It looks great Tom! But I am curious on what kind of project it is, I see the solar panels in the background, did you need to run wiring through the tubing? Please tell me more.
