Video Transcript for EZ Coupler RV Sewer Fitting Kit Review

Today we're going to be taking a look at the EZ Coupler RV Sewer Fitting Kit, part number F02-3303. This kit is going to come with everything you need to adapt your three inch standard RV sewer hose to a dump station. We have our bayonet fitting for our RV side, our 90 degree elbow with the slip fitting for our dump station, and then a coupler so we can connect two hoses together. The bayonet fitting simply threads in place for a gas tight fit. There are no hardware or clamps required. Once in place, the bayonet fitting easily attaches to our RV's black water tank. At the other end of our hose, the 90 degree elbow threads in place just the same.

Then we can attach our slip fitting. We slip it on, twist it to lock it in place, and then we can attach it to our dump station. It also includes an adapter with a 3", 3-1/2", and 4" thread should your dump station require it. It simply slips in place over your slip fitting. If we needed some extra length to our hose, the coupler allows us to connect two hoses together. The 90 degree elbow is going to reduce stress on our hose by preventing it from bending.

It also features a 3/4" threaded fitting so we can drain a second gray water tank. A quick tip when draining your tanks, you want to be sure and empty out your black water tank first followed by your gray water tank. By doing so it's going to help flush out any remaining solid waste particles in your hose. When you're all done you can remove the slip fitting, put on the drip cap for a clean storage of your hose. That's going to complete our look at the EZ Coupler RV Sewer Fitting Kit, part number F02-3303.

Review from a similar EZ Coupler in RV Sewer Hose Fittings


Who decides on size of box for shipping and do you train them on securing product for shipment? I ordered two wiper blades, two heater door clips, sewer flush king and sewer cap. They were shipped in a huge box (21"x26"). So big that the flush king came out of its packaging from being tossed around inside the box. I'm sure everything was bounced around the entire trip to my door cause there was only one small strip of filler for cushion and the box was crushed onretailer. It could have been shipped in a box half that size. I'm actually not expecting my flush king to stay together long. Disappointed in the shipping package. I guess you take your chances. I never expected this from etrailer.

Review from a similar EZ Coupler in RV Sewer Hose Fittings


EZ coupler cap for waste drain received quickly from etrailer. Fits snuggly on replacing previous cap. It does stick out more from the sewer because of the handle. But I am hoping it helps keep my hands away from touching the sewer pipe opening when emptying, even though I wear gloves, giving added safety from touching contaminated openings. Have not used on trip yet, but my other cap had broken attachment to the pipe and looking worn.


Comments
As previously reported my concern about the handle on the cap protruding out has not been a problem. It has been so much easier to remove and replace the sewerdrain cap with the handle. Happy I made this purchase. I would recommend this handle cap.

Second time ordering from etrailer. In both instances my items were shipped the same day that I ordered them, and I received them a few days later. Items were exactly as described. It is obvious that etrailer feels strongly about getting customers orders shipped as soon as possible and I appreciate that. Never had a problem with the items I ordered, so I can't speak to their customer service. I suspect however, that they will strongly stand behind the products they sell.

This was a difficult product to locate locally, etrailer had the product in stock and we received it quickly. It worked perfectly in allowing us to create a 10' black sewer hose combination that would fit into our Class B undermount tube.

Review from a similar EZ Coupler in RV Sewer Hose Fittings


etrailer is awesome. I always know I am going to get a super high quality product when I order from them. This lowly sewer cap was no exception. It's PERFECT and it fits "right & tight" just like I hoped it would. My old cap had only a two prong connection and the interior gasket had become brittle. Consequently, there was the occasional dreaded drip. NO one tolerates a dripping sewer cap in any RV park. It's a major no-no. This cap is not going to drip. I love the handle so I don't have to grab the back part of the cap to get it off. I also like that I can wipe the handle clean after each use. I love the fact the 3/4 inch hose cap has a dongle. Now I don't have to worry about driving off and forgetting the hose cap. This is a superb product in every way. etrailer's processing of the order was exemplary as usual. Their package tracking is the best. I received the cap a day earlier than the projected delivery. Just another 5 Star Etrailer order! WE LOVE etrailer and we are NOT being compensated for this review in any way, shape or form.

Great etrailer service and a replacement cap better then the original. My original would work it self loose when traveling and eventually fell off. the handle allows for a very tight fit but still easy to remove with clean hands.

Hi. This coupler with the big handle has made doing “tank” duty so much easier. It is sturdy, locks moisture in, and easy for senior hands. If ever we purchase a different RV we will definitely order another


Comments
After a year of use this big handle black tank handle has held up beautifully. No leaks and remains an easy opener for senior hands. Well worth the purchase.

IT's all good with etrailer as usual. We needed the end to complete the included section of sewer hose on our Winnebago Travato. The hose is blue and the adapter is red, so we have a colorful sewer setup.

Ask the Experts about this EZ Coupler RV Sewer Hose Fittings

  • Recommended Sewer Hose That Will Fit Inside 4" Rear RV Bumper
    The majority of sewer hoses won't fit inside a standard 4" RV rear bumper because the molded-on ends which contains the lug and bayonet fittings are too large. However, if you were to go with an option that doesn't have the molded-on ends you could then fit the hose inside the bumper you'd just need to store the fittings and adapters separately. I recommend the EZ Flush RV Sewer Hose part # D04-0054 with the EZ Coupler RV Sewer Fitting Kit part # F02-3303.
