Today we're going to be taking a look at the EZ Coupler 90-Degree Bayonet Sewer Fitting. It's available in clear with part number F02-3112CL or in red, part number F02-3112. This sewer fitting is going to allow you to adapt your standard three inch RV sewer hose to a dump station. The bayonet fittings lock it in place and the black rubber seal prevents leaks.

by:

These are awesome for monitoring the cleanliness of your waste tank but do not work well when the threaded connection is more than an inch below grade and concrete is sloped around the connection. The elbow threads could an inch or so taller. As with all RV trips, you may need an extension adapter.




by:

It took me awhile to figure out that one needs to twist the sewer hose inside of the fitting in order for the locking mechanism to lock. I believe it will do the job nicely though.




by:

Really like the clear feature so I can monitor what is coming out of the RV!




by:

The item came exactly as advertised but I have not gotten to use it at this point. We will see.




by:

Love that it's clear so you can see when clear water is running!




by:

I prefer the clear plastic for reasons that are not for the squeamish... quality control.




by:

Perfect OEM replacement




by:

This should be standard for all sanitation drain hoses




by:

awesome product




by:

Have not used it yet, but looks to be a quality item.




by:

Just as described. Need to wait until I use it to give final judgement




by:

I like this fitting because of the clear view. I would have preferred a 45 degree rather than a 90 degree but apparently a 45 is not available.

Thanks

Kent

The sewer System products all fit together as I expected. Added these on to my current dump hose will make it much easier for setup and tear down.

  • 90-Degree Sewer Hose Adapter That Fits A Standard 3" Fitting And A 3-1/2" Sewer Inlet
    I believe we have exactly what you're looking for, for your 1991 Provost RV. Take a look at the: -EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting # F02-3112CL. This is a clear 90° fitting that will fit onto a standard 3" lug fitting, and will also fit 3" slip and 3", 3-1/2", and 4" threaded sewer inlets. Attached is a review video for you to check out as well.

  • Adapter to go From 3-1/2 inch Diameter Pipe to Bayonet Fitting

  • Will Camco Sewer Hose Seal CAM39313 Work Well with EZ Coupler # F02-3112CL
    The EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting # F02-3112CL that you referenced would work well with the Camco RV Sewer Hose Seal # CAM39313. The # F02-3112CL is designed to fit to dump stations much better than standard hoses and when used with the seal # CAM39313 it would provide a much better seal that would not easily work loose like other seals.

  • Parts Needed To Connect A Macerator Hose To A Dump Station Waste Drain
    Thanks for the clarification, yes, the EZ Coupler 4-in-1 Threaded RV Sewer Adapter # F02-3112CL and Valterra Gray Water Drain Adapter # T1020-5VP will be compatible with each other and allow you easily, and cleanly, dump from your macerator to the drain. I went out to the warehouse and grabbed these items to show you them connected together.

  • Parts Needed To Use A Portable Macerator On A Black Tank Waste Valve
    The bayonet part of the Flo-Jet macerator is going to connect to your 3" black tank waste valve as the input and use a 3/4" garden hose connection as the output so you wouldn't need the EZ Coupler 4-in-1 Threaded RV Sewer Adapter # F02-3112CL or the Valterra Gray Water Drain Adapter # T1020-5VP. You would just need your black tank waste valve to have a bayonet fitting for the macerator to attach to like the # T50A has. If you are unsure if your waste valve has a bayonet fitting you can...

  • Parts Needed to Allow Gray Water and Black Water to Dump From the Same Valve
    It sounds like you might want to have a look at the Bristol Double RV Waste Valves - Elbow - Rotating - 3" and 1.5" Hubs to 3" Lug # 34466ND13AAR, which would allow you to dump your black and gray water tanks from the same hose. This elbow fitting connects to the 3" hub on your black water drain pipe and the 1-1/2" hub on your gray water tank, and allows you to use the # F02-3112CL with your 3" spigot connection hose. You'll need to remove your old valves to install the Bristol Double...

  • Recommended RV Sewer Hose Carrier for Under the Camper & Sewer Fitting Wrench
    The RhinoEXTREME RV Sewer Hoses w Swivel Fittings, # CAM39867 is two 10' long hoses with a compressed length of about 54" and 3" diameter. For storing these, I recommend the Valterra RV Sewer Hose Carrier that adjusts from 34" to 60". Select # A04-3460BK for black or # A04-3460 for white. I recommend the EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting, # F02-3112CL as a replacement for your current sewer adapter. This fits 3" slip and 3", 3-1/2", and 4" threaded...

  • Recommended Black Water Drains Transitioning To 4 Inch PVC Pipe
    To connect your RV to a 4 inch PVC pipe, I recommend the EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting - Clear # F02-3112CL. This adapter will transition from the standard 3 inch RV black water connections to the threaded 4 inch PVC. For your 3 inch connections, you may be interested in the Camco RV Sewer Hose Straight Adapters w/ Bayonet and Lug Fittings and Clamps # CAM39543. To get your two lines into one, you may want the RhinoFLEX RV Sewer Hose "Y" Fitting...

  • Semi-Permanent RV Sewer Connections Made To Septic and Fresh Water Supply Needed - 75 Feet
    Your fresh water hose is an easy recommendation, I suggest the Camco RV drinking water hose, 5/8" diameter at 75' Long, # CAM22803. This is a reinforced PVC hose for drinking water made of FDA-approved materials and BPA-free. Because you state that you are new to RV living I will make the suggestion that you also use a water pressure regulator, I suggest the Camco RV Water Pressure Regulator, # CAM40055. Please see the attached video for a visual of product. Because inconsistent water...
