Video Transcript for EZ Coupler 4-in-1 Threaded RV Sewer Adapter Review F02-3112

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. It has four different fittings. It has a three inch slip, a three inch threaded, a 3 1/2 inch threaded, and a four inch threaded.

The 90 degree angle's going to help reduce stress on our hose. The clear option is going to allow you to see when your black water tank is empty. Pick up the red option if you prefer to not see your waste. That's going to complete our look at the EZ Coupler 4 in 1 Threaded RV Sewer Adaptor with a 90-Degree Elbow Fitting.

This is the perfect RV waste elbow. It's clear so you can see exactly what's happening as you dump, and also it's a one-piece unit. I HATE all the other two-piece units, the tiny little ears get sheared off trying to screw them in or out of the sewer ground connection, or they simply get unscrewed partially, then the top half pops off and it turns into a crappy situation!

Still working great, never leaks or comes loose!

by:
ETRAILER IS AN AWESOME COMPANY!
by:
Just what I needed
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.

Still working well and helping me maintain tank cleanliness by monitoring the outflow as well as volume.

by:
etrailer is the first place I go for my travel trailer needs. Great service and fair prices.
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:
Excellent products at excellent prices; arrived in short order!!
by:
Works great stays into sewer dump pipe even will dumping tanks

by:
Ordered the EZ-Coupler. It came when promised and in good shape. I would purchse from etrailer again.
by:
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.
by:
Direct replacement for original that has become cloudy over the years.

It's so easy to order from etrailer and it was shipped and received in 2 days. Thank you

Super Great. Would purchase it again. Thank You.

by:
This should be standard for all sanitation drain hoses
by:
Perfect OEM replacement
by:
Durable. I duct-taped the small plastic "holding ring" at the top of the picture, and it has held up well--actually, it wouldn't matter if it broke, but it has been useful for storage while attached to the hose. I'd buy this again in a heartbeat.
by:
Can be difficult to find this part. Company was out of this part but they kept me informed of when it would be in and sent it out immediately. Very pleased with their service.

  • What's the Plastic Tab for on the Top of the EZ Coupler 4-in-1 Threaded RV Sewer Adapter?
    Welcome back Mark and thanks for the pic! The tab can be used for securing the EZ Coupler 4-in-1 Threaded RV Sewer Adapter item # F02-3112CL. That's actually a new feature they've added. It can be used for hanging the adapter up or tying the coupler down to the dumping station if it doesn't have threads. Some people also secure their end cap to it with some rope or thread. Do you plan on storing the adapter with the sewer hose or removing it? You can add this information, along with...

    Hi Harley! We have the following options that will have a clear elbow: Camco RhinoFLEX RV Sewer Hose w Swivel Fittings, 4-in-1 Adapter, and Storage Caps - 15' Long # CAM39761 EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting - Clear # F02-3112CL Lippert 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting - Clear # LC67UK However, all of these will fit a 3" slip and 3", 3-1/2", and 4" threaded sewer inlets.

  • Sewer Hose Recommendation for Lippert Waste Master System
    You have the Lippert Waste Master Camlock Connector on your 2018 Forest River Forester so for a single hose setup you need the Lippert Waste Master RV Sewer Hose w/ Leakproof Camlock and 90-Degree Nozzle # LC359724 to dump your tanks. This comes with a 20' sewer hose but if you end up needing more length than that you can use the kit # LC360784 which comes with a dual Camlock Coupler and another 20' length of hose (when expanded). With that being said, it looks like the previous owners...

  • 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...

  • 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...

  • 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...

  • 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...

  • Is the EZ- COupler 4-in-1 Threaded RV Sewer Adapter Easy To Install On/Off?
    I would say the EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting # F02-3112CL is considered to be easy to remove. This fitting easily twists onto any 3" lug fitting, has an internal seal that will prevent leaking and will let you see when the tank is empty due to the plastic being see-through. I would recommend that if you still cannot get this fitting on/off to just ask a neighbor for help or you could also bring it to a certified RV tech and they'd be able to...

  • 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...

  • 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.
