The side out weather strip seal is one of the most important seals on your RV. Designed to completely seal the large opening of your slide out, this seal prevents water and unwanted debris from causing costly damage to your RV’s interior. Eventually, this seal becomes warn or damaged and requires replacement. In this RV how to video, Mark Polk – KOA’s resident RV Expert – demonstrates how to remove and install a slide out seal.

Top Tips From This Video

  • When you order your seal, ensure your measurements are accurate
  • Remove the old seal using a plastic scraper if it is applied with adhesive
  • Ensure you clean the area under the seal well – but don’t worry about removing all the adhesive
  • To install the new seal, push it onto the pinch weld which has a raised edge – the seal will lock on this edge
  • With a push on seal, adhesive isn’t required, but can be used if you like – just make sure it is compatible with rubber
  • The corners and top are especially important as this is where the most rain hits the seal
  • You will need to cut and glue the wiper to fit properly around the corner of your slide out
