Dealing with your RV’s waste tank is a thankless job, and it’s one no one enjoys. But if you’re using your RV’s bathroom comfortably, someone’s got to take care of it. And that means you have to have quality equipment connected to your “sewer” system, like durable hoses and tightly closed fittings so you aren’t dealing with an even bigger (and grosser) mess when it’s time to clear out your tank.

Buying Guide/What to Look For
RV sewer hose fittings are pretty simple, and they only have one specific use. But that doesn’t mean you shouldn’t take the time to do a little research and comparison shopping to find one that’s high-quality and highly reliable. We’ve got tips, tricks, and plenty of information to help you begin your search for a great RV sewer hose fitting that’ll meet your needs.
What to Consider When Buying RV Sewer Hose Fittings
Types of RV Sewer Hose Fittings
Generally, RV sewer hose fittings are any extra connections done on the sewer hose that improve the connection between the RV waste tank outlet and the campsite sewage dumpsite. This consists of the adapter, hose support, and connectors.
The sewer hose adapter either attaches directly to the RV sewer outlet connection or the dumpsite. A straight adapter is typically connected to the RV outlet while a curved adapter (at an angle of about 45-90 degrees) goes on the dumpsite port. Curved adapters can also be used if you have limited space for a straight adapter.
As the name suggests, connectors are fittings that link two parts of the sewer hose. There are different connectors for each part of the sewer hose, and they’re designed to ensure a secure, odor-tight connection. They include lock and central connectors.
Lock connectors are used to secure the hose to the adapter. You can have two connectors, one that connects to the adapter on the RV waste tank outlet and another that secures the adapter connected to the disposal valve. Some lock connectors can swivel 360 degrees to make it easier to connect or disconnect the hose ends. Central connectors are used to fix a hose extension so it’ll be long enough to reach the campsite sewage disposal unit.
If your vehicle is parked on an incline, the gravitational force will help the fluid flow easily through the hose into the drain. However, you won’t have this advantage on level ground. This is where the hose support comes in. It holds the sewer hose in place to help completely empty the tank and helps reduce wear and tear. It typically has an angled cradle for faster draining and a flat bottom to provide ample support and protection to the sewer hose.
RV Sewer Hose Fitting Key Features
The size of your RV sewer hose fitting should be compatible with the sewer hose and tank outlet. To avoid making fitting mistakes, buy fittings that match the brand of your sewer hose. The tank outlet size will determine the size of the adapter you get. You may not experience fitting issues if you have a new RV since they have standardized tank outlets. However, if you have an older rig, you need to be keen on the exact size of the outlet to get the right adapter.
Select a fitting that features the best build so it can last a long time without cracking or coming loose. Prioritize thick fittings that can withstand the pressure coming through the hose without detaching. The main point is to have a sturdy, leak-proof connection. Also, shoot for odor-tight connections, especially with the end caps and connectors.
Aside from that, you want to ensure that the fittings have a smooth interior so that waste particles don’t get stuck inside. The exterior should have an abrasion-resistant design that doesn’t wear out easily, even when used for an extended period outdoors.
One of the main reasons sewer hose fittings deteriorate is frequent exposure to the elements. Therefore, having a weatherproofed fitting is key. Choose a fitting that’s designed with UV-stabilized resin so that it can resist damage from intense UV rays. Also, it’s possible to get a fitting that can withstand being used in freezing conditions without cracking.
Tips and Tricks
As with something you do for decades upon decades, you pick up a few tips and tricks along the way in terms of selecting the right product, and/or using it. That’s the case with us and RV sewer hose fittings. To help you bridge the information gap, here’s a selection of what we’ve learned along the way.
- A clear RV sewer hose fitting might seem gross (who wants to watch waste?), but it’s hugely helpful, as clear fittings make it so much easier to tell when your waste tank is empty and done draining.
- If you do opt for a clear fitting, make sure you detach it once you’re done draining as they aren’t made of highly durable materials, so they aren’t meant to stay on your RV permanently.
- Always make sure your fitting is gap-free once it’s in place. Gaps mean odors can sneak out, and that’s something you definitely don’t want to experience.
- Having trouble getting your RV’s sewer system set up securely? You can use a sewer fitting wrench, which is designed to give you better leverage and more strength to make sure you have a tight connection.
Q: Are RV sewer hose fittings universal?
Most RV sewer hose fittings will work with most RVs and sewer hoses, but they aren’t always a perfect fit. Some fittings require you to use hoses by the same brand or manufacturer. Others can work with many different hoses, but you’ll need to make sure the measurement of the fitting actually fits the hose in question.
Q: Does my RV sewer hose fitting need a gasket?
If your fitting doesn’t have a built-in gasket, you’re going to want to upgrade to one that does. While it’s not mandatory, gaskets offer a tighter, more secure leak-proof seal when your sewer hose is connected. And that small addition can block both unwanted waste leaks and odors to make draining a more pleasant task.
Our top pick is the Camco RhinoFlex RV Bayonet Elbow Fitting, which offers a well-thought-out design that allows you to see when the waste tank is fully drained and forms an odor-tight connection with the dump station valve. If you’re looking for a cheaper yet reliable alternative, consider the Valterra T1024 Hose Adapter. It provides a universal fit and offers a secure connection.
