Video Transcript for Camco RV Sewer Drain Cap Review

Today we're going to be taking a look at the Camco RV replacement sewer cap, part number CAM39452. Just going to go over your gray water reservoir tank. For some odd reason your cap is missing, or if the black rubber piece breaks off, this is going to help keep it attached. This cap will simply replace your old cap, and also does have the included tab here, which is going to replace and secure it back on here. It does feature the 4-bayonets, so it's the standard 3 inch diameter cap that will fit around the 4 lugs of your standard 3 inch diameter waste tank. We'll simply just slide it on, give it a little twist. It has this nice handle here that allows you to grip onto it and give it a nice turn.

Now that seal in here is going to help prevent leakage and drips, giving you a real tight, snug hold. Then also, when taking it off, this nice long handle allows you to easily take it off instead of having to grab it from here; and then again, with this being attached here, it's going to allow you not to lose the cap. Now with our replacement cap on, that will complete today's review of the Camco RV sewer drain cap, part number CAM39452. .

This sewer cap prevents leakage from your RV's waste drain. 4 Bayonets tighten onto the drain for a secure connection.


The o-ring on my old cap broke. It’s was cheaper to order the cap than the o-ring. Exact fit.


It’s been a year. Still working fine

Great-fitting product! A solid replacement for your RV sewer drain. No leaks on mine!


Reviewing a Sewer cap..what can you say.
Doesnt leak, has 4 lock pin slots, the full bar 'handle' is easy to use. This was used on our portable auxillary waste tank. Another replaced a 2 lock pin cap on our camper.
Good price


Perfect fit. The material seems a little flexible and therefore may be less likely to crack like the original. Happy with the purchase.


Cap fits better than the original and appears to be of a better quality.
Always a pleasure to deal with this cmpany!


Delivered on time and work as expected!


Transparent, timely.


Well I can't say they'll fit because our trailer is already closed up and winterized for the season... These are replacement parts so I'm sure they will do the job just fine for next camping season in May! Thank you very much, these came in just a few days. I only wish that I had ordered them much sooner.

My parts are working fine as I knew they would. Good quality too. I know where to order future parts now!

Excellent customer service! Right part first time! Thank you so much for your help!


The product is just what we need and the service was exceptional!!


We are using a tote tank as a main black water storage/tote tank on a non-travelling Tiny House. Thus, I had to do a somewhat unconventional hook up. Never having dealt with the RV side of plumbing I was concern I might order incorrect parts.

The product videos on the etrailer site were VERY helpful. Not only did you show the product, you also gave actual measurements that went a long way to ensuring I got the right parts. THANK YOU, Thank You, thank you.


Love etrailer. Customer service excellent. Quick deliveries. Have shopped them multiple times. Love the variety of items.

It been a year WOW! Still using and perfect condition. Like it.

No leak replacement to our broken cap that came with the TT.


Fit like a glove. Like it a lot


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.

The new setup is much easier to use. My wifes only comment has been why didnt I do this years ago
George - 06/29/2021


Absolutely love the quality. I bought for thinking it was going to be like the one that came with the camper. It isn't even close. I haven't replaced it with the other three yet and out looks like brand new still a year later. The one that came with the camper that has only three locking points (the same amount of camping trips until it broke) is so inferior to this one. It is not only better material, but has four locking points.


looks to be very solid and well made. Order was problem free and received quickly


The tether was missing from the camper sewer cap I ordered. I was pleased that I was able to promptly reach a live customer support person by phone. When I informed etrailer representative Kaleb about the missing tether, he discovered tethers were missing from their entire warehouse inventory of sewer caps. I was assured the missing tether would be sent to me by etrailer's manufacturer, but have not received one yet.


Great service, great product.


Good replacement cover.


like ordering from etrailer-prices are great service is uper fast. KUDOS to etrailer-products good quality

This sewer drain cap replaces one that broke during our last trip. Had to make it home with the old cap secured by duct tape. Like the raised handle on this new one to facilitate opening and closing. Also like the four bayonet slots on this new one, more secure than the old with only two.


My package of fittings arrived right on time and were put to use immediately when I took them to our local building supply to verify piping sizes and temporarily assemble and measure a mockup of our drain line. It was a great help to do that, as I discovered that hard-plumbing the sewer line was a bad idea. Instead, a flexible/removable joint was added close to the "L" adapter to the septic inlet, which will allow for removal of the line in winter and ease repair efforts in case the line gets plugged or is damaged.


Works real good used it on my 1975 16 foot cardinal trailer

Still works good no problems after 1 year
