Video Transcript for EZ Coupler RV Sewer - Hose Adapters and Fittings - F02-3303 Review

Today we're going to be taking a look at the EZ Coupler RV sewer fitting system. This is a self threading system for secure connections. It does not require clamps to secure the fittings to your hoses. It's going to work with right or left handed coiled hoses. This kit's going to include everything you see here on the table. You're going to have your valve hose adapter. That would be this piece here, threads into one end of the hose, and then it provides the four bayonet hooks for secure leak proof connection.

That's included, nice seals in there well for a leak proof connection. You're also going to get your self threading hose coupler. This is designed to connect two hoses together, or to add an extension. Then you're going to get your universal sewer connector that's designed to fit most RV sewers. This is a two piece design. It's going to include a drip cap right here. This is the piece that would be connected to your hose.

Threads on, you don't have to worry about any type of clamps or any additional hardware to get it secure. It just threads into place for a nice, tight secure connection. On this end, you're going to have your drip cap. That's going to provide clean storage. You can leave this piece connected to your hose. That's one of the neat things about the two piece design is it allows for easy storage, it allows you to keep this piece connected to the hose, and then you can put the drip cap on there for clean storage. It's got a bayonet style grip in here, so you place this in, rotate it.

Hose would be connected here. This piece right here goes into the sewer connection. This right here is a 3/4" threaded connection for drainage of a second gray water tank. This is a pressed to fit design, so it's got multiple tiers right here that allows it to fit a wide range of sewer connections. Just place it in the hole, press down on it, and it's going to provide a nice, tight, secure fit. We'll give you the diameter measurement right here on the slip.

At this point here, we're looking at a 2 3/4" outer diameter. This kit's made from a durable construction that's designed to last for a long time. Last thing I want to point out is sometimes, these drip caps can get in the way. There's a little stay right here that you can just snap that into. It's going to keep it out of the way. The drip cap's held in place with a tether, that way you don't have to worry about misplacing that or losing it. That's going to do it for today's look at the EZ Coupler complete RV sewer fitting system.

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!

Great product. I can open the small cap to drain any little accumulation in the pipe before taking off the main cap.Seals very well.

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


Bought a couple of these as we needed 2. One of the standard manufacturer ones cracked in cold weather so I found these. They are much better quality than the flimsy ones you get standard on an RV. Love that they have a handle for easy on/off. Definitely would recommend

Review from a similar EZ Coupler in RV Sewer Hose Fittings


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.

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 coupler cap is an upgrade of what came with our travel trailer. Much easier to manage, more useful, and a safer product. Best of all--never have to touch the rim of the cap touching the black tank outlet. Thank you!

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.
