Slide-out seals are an important part of slide-outs. They keep the moving pieces clean and protected, they keep the parts free of dirt and debris, and they create a transition from the RV frame to the slide-out piece. It's easy to see why you shouldn't skimp on your slide-out seal. The seals stick to the outside of your slide-out, on both the slide-out section and on the RV frame, to create a barrier from weather and other elements. Even when the slide-out is closed, there are still possibilities for natural elements to make their way into the RV frame, which is why the "D" bulb seals are so important. Creating a tight seal between the closed slide-out and the RV frame, the "D" bulb seals are just as important as the standard flat seals. Our seals are easily applied, with an adhesive already stuck to the seal. Simply cut to length, pull the tape off of the seal, and apply to the area. Without having to use an extra adhesive, you can do the repair on your own, rather than visiting a repair shop. The pressure-sensitive adhesive grips to the surface better than most commercial-grade adhesives, giving you a watertight bond that lasts through years of RV adventures. Properly applied, you won't have to think about your RV seal for a long time to come. With the multiple lengths, you don't have to settle with too little or too much. You can choose the length of your piece and have control over how much tape is coming your way. When it comes to your slide-out, you don't settle for only OK furniture or decorations inside, so why settle for just OK seals and protecting fixtures outside? High-quality seals can make a difference to the life of your slide-out, so don't just settle for OK. If you're looking for the best seal, these high-quality RV slide-out seals are exactly what you need.
