Video Transcript for EZ Coupler RV Sewer F02-3106BK Review

Today we're going to be taking a look at the Valterra Easy Coupler Valve Cap with the Built-In Handle. This cap is made from a durable black plastic construction. It's going to feature the built-in seals to offer leak proof performance. It's going to fit onto a standard 3" valve. It's got the bayonet style fitting right there that allows for a really nice tight, secure connection. This caps going to feature the four hook design, so you place it onto a bayonet-style fitting, rotate it to interlock the hooks with the tabs, and that's going to secure the cap in place. It's also going to feature a 3/4" gray water drain connection.

That's this piece right here, it simply threads on. That's your connection point right there, again, 3/4" gray water drain connection. The fitting right there, inside the cap, also is going to have an internal built in seal for leak proof performance. Once that is on there you don't have to worry about anything spilling out, or seeping out. It's got the convenient easy grip handle, it makes placing on, and taking off the cap quick and easy. It's going to come with the appropriate tethers to prevent you from misplacing or losing the cap, or the 3/4" cap right there for your gray water connection point. That's going to do it for today's look at the Valterra Easy Coupler Valve Cap with the Built-In Handle..

EZ Coupler Cap for RV Waste Valve w/ Handle and Gray Water Drain - Black - F02-3106BK

Average Customer Rating:  4.9 out of 5 stars   (518 Customer Reviews)


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 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.

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

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


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.

Still working great. Just used it yesterday.

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!


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.


The handle is just what I need. I had to use a large channel lock plier before,now it’s a simple twist, and there’s a way to attach a hose to drain the grey water tank.


It made good. It's just a cap . But it's not cheaply made .

Its just a cover, working good

I love having a handle on the cap - it makes it so much easier to align and twist the cap. It deals well. I highly recommend this style.


We love the handle,makes it so much easier to remove.


Looks good.. really like the handle


Fits perfect. Exact replacement as needed. Quick ordering and fast hassle free delivery.


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.


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.

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.

Excellent product, fast service always!


Both products are strong and fit nice and tight.


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


Love the fast response on our order. We have to replace the coupler cap on our RV occasionally and it is good to know where we can solve this problem in a timely manner.


Just what I ordered and received it on day promised.


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.


It worked superb. Now if necessary I can open that valve. My hand would not go around the k
Original one.


Exactly what I wanted


Love this cap, works great and so easy for me to open.


The quality was spot on
Thank you all
@ etrailer


Awesome service Great product Great Quality fits perfect Easy turn for my arthritis hands
