Video Transcript for Let’s Check Out the Rubber Bulb Seal for RV Slide Out

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this 30-foot-long slide-on bulb seal with the C channel for your RV slide-out. This C-channel rubber seal is used to prevent water from leaking into the slide-out on your RV. This is ideal for the 2010 Bighorn by Heartland fifth-wheel and other RVs. This will seal against the RV when the slide-out is closed. Wanted to zoom in and show you the design we're talking about.

If you look closely, has a unique hourglass design right up here at the top. Helps prevent side-flop when it's compressed. It's protecting your RV from any extreme weather and pests. At the very bottom, you can see it has a rigid C-channel section, and that's what'll slide onto the track that's located on your wiper seal. This is designed to work with the stick-on wiper seal with the track, which we do sell separate on our website.

It works with the part number SR99FR, SR27FR, or the SR67FR. Again, those three items are sold separately on our website. Dimensions on this; total length is 30 feet long. The width on this is 1 3/16 inches wide. Overall height, 1 3/16 inches tall.

This part number is a 30-foot-long section. We do also sell this in a 15-foot-long section. It's part number SR57FR. They also do it in a 60-foot-long, which is part number SR97FR. Again, those are both sold separately on our website.

This part is made in the USA. But that should do it for the review on this 30-foot-long slide-on bulb seal with the C-channel for your RV slide-out..

I got on etrailer and instantly Amy was MY customer service rep. Above I ordered the wrong part but through entrails videos I learned what was the correct part for my RV. I’ve heard so many good things about etrailer. I’m going to continue my travels with them by my side for any parts, and education through their videos. That’s why I give them five star rating.



by:

Worked just fine



by:

Good quality product, but installation not nearly as easy as videos depict. Despite lubricating the wiper channel, friction made installation a challange.



by:

Great bulb seal. A lot thicker and more dense than I expected, but overall it should work great!



by:

So far so good. Installed easy. Seems to be much sturdier than the OEM on the unit.



by:

A little different than the original,but work satisfactory. It was a bit difficult to install due to my inexpensive and cordination. Next



by:

I received it in a timely manner. Packaged nicely. Exactly what I ordered. Seems to be very durable a lot better than what I have on my RV now. Have not installed it yet, but I will follow up.



by:

So far, so good! Definitely much better than the original installed on the coach. It’s a bit tricky pushing it through the grooved track, especially if it’s a longer slide out. You have to push it then pull it from the other side. Some silicone sprayed in the track helps.



by:

Worked out great….



by:

2013 forest river windjammer. Fits perfect thanks



by:

much better quality than the original slide out seal



by:

Our 12 year old class a motorhome super slide was leaking. Our first plan of attack was replace the bulb seal. Ordered from e trailer. Installed it. Slide still leaked. Took it to the local rv repair center. They recommend resealing the roof and all seams on the rv. That solved our issue. They did say the new bulb seals were installed properly and doing their job. Reason for all this is to say we had no idea how to replace them but the product performed well and we completed that part of the repair on our own.



by:

Fast delivery, Was easy to install



by:

Jerry B. was very helpful to me to select the right RV bulbs to go along with the slide seals I needed



by:

The customer service is outstanding, very helpful with very prompt shipping. The product is of very good quality.



by:

Seems like an excellent product. Much studier than what came with the camper. Ordering and delivery from eTrailer was easy and fast. Item is installed and now we see how long it lasts. Easy install.



by:

So far so good! The original rubber seal on my Keystone Springdale lasted 14 years. Unfortunately I replaced it with an inexpensive seal that was thin and flimsy and literally only lasted months. As soon as I opened the box from e-trailer I could tell their seal was far superior. The construction is thicker and far more solid. Time will tell but I have high expectations based on the quality of rubber and design.



by:

I’m still installing rubber seals on slide out. Product is superior. However, installation videos should show people doing the actual work, not just talk about quality and dimensions of product. Rubber is hard to slide in tracks. You should recommend a lubricant or demonstration to allow a smoother installation.



by:

The service was great and the bulb seal is much more stout, than the ones that came as original equipment.

Thanks etrailer.

Fast delivery box was damaged so haven’t looked at it yet to make sure all is good will tonight



by:

My order has arrived. Everything is perfect. Thank you et have a great day.



by:

Product is just as described and was delivered very quickly. Thankfully it was a 30’ roll and hard to lose as the packaging was not intact when delivered. Somewhere along the line, the shipping and handling needs a bit of work. Would have done 5 stars but it could have been a bit of a fiasco if there were small pieces involved.



by:

The seal fit a little loose on the track. However it works. Shipping box was is in bad shape but the seal was not damaged.

  • What Wiper and Bulb Seals Do I Need for My 2021 Forest River Sabre Cobalt 32D?
    Hello Jessica, Thank you so much for getting those pictures to me. I reached out to the manufacturer and they confirmed that the correct wiper and bulb you will need is the # SR67FR for the wiper, and the # SR37FR for the bulb. He said they will work as good if not even better than you OE seals. It was nice chatting with you in our emails. Let me know how you like the new wiper once you get it installed.

  • Recommended Replacement Bulb Seal for a 2020 Forest River Sabre Cobalt
    Perry, so it looks like the closest we have to what you measured is the Rubber Bulb Seal for RV Slide Out # SR37FR, which measures 1 3/16" wide and 1 3/16" tall, which is 1/16" shorter x 1/8" wider than what you measured. If you're uncertain about your measurements, I'd just try again taking a piece off the seal and measuring the width and height as is.

  • Determining The Correct Wiper Seal And Bulb For A 2016 Rockwood Roo Travel Trailer
    To get right seal you'll need to remove a small portion of the seal to get the side profile of your current seal. There are multiple types of applications for slide-out seals/bulbs; Glue On, Peel-N-Stick, Press In, Push On, and Slide-On. There are multiple styles and measurements the seals; some seals come with a bulb, some don't. For example the Rubber Bulb Seal for RV Slide Out # SR37FR is a bulb seal that will slide-on to the track on a wiper seal like # SR67FR. If you can pull just...

  • Recommended Bulb Seal Replacement For A 2019 Forest River Sierra Fifth Wheel
    The channel on the # SR37FR would be approximately 1/4" too large so you'd want to go with the Rubber Bulb Seal for RV Slide Out - 1" C-Channel # SR84FR instead. This bulb will fit much closer to your 13/16" channel. I do recommend drilling a small hole every few feet through the outer bulb and using a screw to secure the base of the bulb seal to the track once in place.
