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


I bought three replacement valve caps with handles, two for my dads trailer, one for mine. Dad is 75 and doesn’t have the hand strength he once had. I have broken my hand and wrist more than once, and can not get a good grip on the standard caps. These caps with handles have made the world of difference! Highly recommend etrailer! Excellent customer service and lightning fast processing and shipping!

Review from a similar EZ Coupler in RV Sewer Hose Fittings


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.


Comments
One of the best purchases from trailer, works perfect and the cord never lets you to forget to put on

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.

This ez coupler 20' Deluxe Bayonet Sewer Kit in RED is exactly what I was looking for. I had a question about if it had the clear 90-degree bayonet fitting and the salesman had it pulled from the shelf to check it for me. The salesman was very nice and helpful. I would definitely do business with etrailer.com again We've had this product before and really liked it.


Comments
Great! We are very pleased with this.

Heavy duty hose. Fittings at both ends are solid and connect firmly.

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.

Both products are strong and fit nice and tight.

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.

Review from a similar EZ Coupler in RV Sewer Hose Fittings


I have ordered products on 4 different occasions during 2021 and have never had a problem whatsoever. My most recent order arrived yesterday December 17, 2021. It's important to note that each order was in a different product category. Some were products for our 2005 Toyota 4-Runner and others were accessories for our Jayco camper. Each time, the products were exactly as indicated, arriving on time and undamaged. I consider etrailer's customer service to be superb for several more reasons. First, they allow you to ask substantive questions through their email system and will respond intelligently within 24 hours. Also, their demonstration videos for each item are very helpful in determining whether you are looking at the product which best suits your needs.

Lastly, I noticed several negative reviews regarding the poor customer service when people call in to etrailer. My opinion is that given the times we live in, it is simply becoming too difficult for venders to offer effective and timely phone customer service. I might add, who has the time to waste, being put on hold for extended periods of time anyway?
Hope this review is helpful to some.

Thanks again etrailer.

This has a nice handle that will help with removing and putting it on. Having older hands, I struggled with the existing cap. I never thought about draining the grey water with a hose, but I can see applications for that.

I love the handle on this cap, because I've always had trouble removing the original. Almost makes me glad I lost that one.

See what our Experts say 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.
