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..

  • 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.

  • 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. May 2025 bring you many Awesome Adventures!
