Video Transcript for Valterra RV Sewer - Connectors and Fittings - F02-2025BK Review

Today we're going to take at look at the Valterra 3" straight drain hose coupler. Now, this is a black hard plastic construction, this is used to connect two 3" hoses together. A few dimensions on this, the internal diameter is 2-7/8", the overall length one end to the other is 3-1/2". But that should do it for the review on the Valterra 3" straight drain hose coupler.

Perfect fit and finish! Thanks!


My grey and black sewer lines were damaged after being forced onto the interstate shoulder by a semi. I tried to replace the ABS pipes from local HW stores to no avail.A After five minutes on the phone to etrailer I not only found all of the components but they shipped them out right away. I am very happy with both the products and the customer service.


Just what I wanted. I was repairing my septic tank I installed a 3 inch black pipe into the tank and I needed a black pipe to fit inside this pipe which I found out they don't make. so this fitting worked just fine.


works great easy to use


Works good...




Fast service and delivery.



Seems great up to now.



Fits perfect

  • Can Sewer Hose in Lippert Waste Master System be Trimmed Down Shorter
    A sewer hose that is too long is an annoyance. One that is too short makes for a mess! It is possible to trim the hose down, remove the parts inside of the end that you cut, then use some solvent, # A05-0303, to "glue" the now shorter hose inside of the one end. Or you could cut a section out from the middle of the hose and use a coupler such as # F02-2025BK with the solvent above to secure both ends into the coupler. If you always need the same length hose then this is a viable option....

  • What Size Straight Coupler is Needed for Repairing RV Sewer System with 1-1/2-Inch Pipes
    We do have a straight coupler that connects 1-1/2 inch diameter pipes, # D50-2933. This coupler does not slide inside the pipes, but rather slides over the pipes to connect them. The connection can be secured with ABS solvent bond, sold separately, # A05-0303.

  • 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...

  • Sewer Drain Valve and Hose Needed for Current Drain System
    Since sewage connectors do need a proper seal (typically by using solvent # A05-0303) I do recommend changing out some of your sewage pipes as they are looking a bit rough. It does look like you have a 3" round pipe from your photo so if you were to keep your current system you could possibly use a Fernco rubber sleeve to connect the Valterra Coupling # F02-2025BK to either an extension or to the Valterra Bladex Waste Valve # T50. If you need an extension you will put this waste valve...
