Video Transcript for Review of Ventline Replacement Dome Seal For Ventadome Trailer Roof Vent - BVD0455-01

Hi, everybody. Andy here with And today, we're gonna take a brief look at this replacement dome seal for the Ventline Ventadome trailer roof vents. This seal is going to keep water from entering between your dome and the base when your vent is closed. And this seal, as you can see, has a flexible design. It feels very durable.

And this is going to work with Ventline vents manufactured after 2008. And this is also going to fit older style Ventline roof vents as long as it has a rounded dome. This seal will work with metal flanges. And this is made here in the USA and you're going to receive this one seal. And it's 52 inches long and it's 3/8 of an inch thick.

And I did want to point out briefly, at the bottom of the seal, it has a split design, as you can see. This is the portion that's going to get pushed down onto your vent. So, when you're replacing your seal, this portion right here is going to get pushed onto your vent lip and the seal's going to push right on. I do wanna recommend using a few dots of silicone sealant. That is going to help ensure that this seal stays in place.

And if you're in need of some sealant, you can find that here at Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

This will be the second time in six years that I have replaced this gasket. Removal and installation are straight forward. I have experienced that this product actually shrinks a little bit. I would like to see a small squeeze tube of some sort of adhesive to help keep the gasket where it is installed.

I would recommend using a few small dabs of a silicone sealant to keep the gasket in place.

After one year this vent seal is still performing well. I recommend this as an easy and cheap fix for an old and cracked seal.


Needed to replace a fossilized seal on a 1988 motorhome vent. This replacement seal fit perfectly. Very pleased.


Great replacement for our weathered seals. They do require a little trimming and recommend using silicone adhesive (as stated in the video) to secure the seal. Removing the old seal did take a little time but was not hard-but you are working overhead.


They were very easy to put on and the fit was excellent. You guys got them sent right away. So I am able to leave sooner than expected. Good job! I will definitely be ordering more products from etrailer.


The seal applied easily. They recommended putting some adhesive to keep the seal in place.
I did not have any at installation time, but will put something to hold the seal in place.
Without it, the rear portion of my seal folds in and comes off the lip when closing the vent.
Word to the wise FOLLOW DIRECTIONS!


Thanks again for having the replacement parts I always seem to need.


Thanks for etrailer's willingness to answer my questions. The BV0554-01 was the perfect replacement for the dome that was on my trailer even though the dimensions of my opening were 13" x 13" not the 14" x 14" as your web paged suggested. The dome was exactly like the original equipment one on my trailer that cracked.

I ordered the white one even though there was a question in my mind whether it would let enough light in. I was tempted to order the smoked one. The white one lets in plenty of light. Frankly I am not sure that the smoked one would allow more light in.

The new dome was easily installed. I think mine is probably missing some sort of a nylon roller on the crank arm. At any rate, I did not have to remove the screen and the crank assembly to replace the dome. I simply opened the dome all the way and was easily able to adjust the dome and pop out the crank arm. Maybe not having the nylon roller allowed me to do that, I don't know. Sliding the old dome hinge out was simple and sliding in the new one was equally easy. I also replaced the dome gasket (BVD0455-01) that was dried out and cracked. That was also easy, but was a little more tedious sliding it around the curves. In total the repair took less than 10 minutes.

All in all, my etrailer experience was excellent. They quickly answered my questions. In fact Jameson Clark responded to my questions at 7:00 p.m. on New Year's Eve. I was amazed. Give this guy a raise. He understands what excellent customer service is. Thank you Jameson.

I ordered the dome and the gasket on Tuesday Jan. 5. They shipped it out on the same day. I did not pay for expedited shipping but instead opted for economy shipping. the order arrived on Saturday Jan 9. I recommend etrailer. I will surely use them again.


Fast delivery and simple to install. Tiny rib on side goes to the outside as per the etrailer instructions. Did 3 vents in about 15 min., off with the old and on with the new. Trimmed about 1/4 to 3/8 inch off each length for a good fit with scissors.
Very pleased.

Expect them to last years.

etrailer is the best. Great customer service and great products
Brent in the team are Awesome


Worked perfectly


Trim to fit. Works perfect


Product quality is important with most products coming out of China now. And while product quality might not be what we came to know and expect from many years past, I do trust etrailer to offer some of the best quality RV products that might be available in today's markets at some of the lowest prices available. And while not yet installed, these seals will surly last as long or longer as mine from Forest River, now only three years old and failing.


Another product that arrived and fit as stated. Replaced my old rotted seal in five minutes. Fit my vent perfect, no trimming necessary.


As sold - as expected - why wouldn’t they be?


Gaskets for roof vent arrived quickly and in good shape. As always!


Exact replacement for original weathers trip.


Purchased the camper trailer roof vents and the dome seal from Etrailer and these are great parts, no problem at all with these parts and easy to put on. I recommend etrailer for all your parts. Delivery was great also.

The products are still great, no problems whatsoever. I cant thank you and the company enough for the products that I received. When the time comes that I need camper products or just trailer products, you can bet Ill be on your site ordering what I need. Thanks for reaching out to me!

Fit perfectly.


Seems to be okay. Has had a little shri nkage.

Seems to be holding up ok. Summer heat is hard on seals. Time will tell.

As usual, etrailer shipped my order in in very timely manner and the Dome Seal for my Ventline Roof Vents was exactly as described on their web site. The hardest part of installation was removing the old, brittle seal. Other than that, the install was a very easy.

Dome seal is working great!
Garry - 05/10/2018


The product was exactly what I needed. A little extra length on the seal made for a perfect fit. I took the time to completely clean the old sealant from the metal flashing using a dremel tool wire wheel. I applied sealant while installing the new seal, took my time on the corners, didn't have to stretch it at all. My old seal had pulled away from the rounded corner. The Vent is now water tight, and looks great.
Excellent product, fit perfectly and was shipped quickly. etrailer gets an A+.

The vent seal has been installed for a year now, Thru the rain and blazing sunshine. It still looks and works great! No leaks, No discoloration, and no shrinkage. Thanks again for the great product, and customer service!
Mike - 08/17/2017


Exacttly what I needed and at a great price too! Thank you, e-trailer!!


The replacement seal for my roof vent fit very well. It was about one half inch too long (which is a good thing) so I just cut it to fit. I used several small dabs of sealer to assure it says put. Both roof vents now seal shut very well. Thanks

The seal for the Ventline roof vent is still working fine after 50 inches of Florida rain.

Works perfect! Excellent price. Being a first time rv owner and not knowing much of rv's. i went to my local rv supply store and was told i had to replace the whole vent. I said, all i need is the gasket on the top edge, again i was told to change the whole vent. Well, $90 in parts, new vent, gasket material, roof patch, etc, i replaced the roof vent. When checking the other 4 roof vents the gaskets were gone on them too. I was not going to replace anymore vents! After an extensive search on the internet i found this product. Thats the last time i go to the local rv store and being taken advantage of. Rv forums are a great place to gain knowledge of repairs imo.
