Keep Wind and Rain Out of Your Camper with RV Slide-Out Snap-In Seals

To keep your RV in working order and prevent damage from the elements, you must regularly maintain your slide-out seals. If you’re waterproofing your camper slide-out, ensure you seal out moisture in all its forms, from rain and dew to sleet and snow. Our camper slide-out seals are rigorously tested to withstand extreme weather conditions, ensuring long-lasting protection.

Trim-Lok aims to make slide-out seals for RVs and gasket maintenance easier than ever with our patented and all-in-one, living-hinge system. This snap-in design combines a three-ribbed bulb seal and flap into one design to make maintenance and repairs simple and easy.

Why do you seal an RV slide-out?

If an RV slide-out isn’t properly sealed, air, moisture, and daylight can find their way into the vehicle—reducing the comfort, safety, and luxury of your RV or camping experience. Trim-Lok’s 3M™ Pressure-Sensitive Adhesive is both an installation aid and a water barrier. By using our snap-in RV slide-out gasket, you’ll prevent unwanted leaks for a more pleasant traveling or camping experience.

How to Install RV Slide-Out Seals

To install our single-flap Snap-In Seal, follow these steps:
  • Clean the application area on your RV or camper
  • Cut the amount of seal you need for your slide-out room
  • Peel back the 3M™ Pressure-Sensitive Adhesive liner and apply the seal to the wall
  • Use staples or screws at six-inch intervals to provide additional strength for the seal
  • Push the bulb down along the seal to snap it into place
  • Complete this process for each side until you have completed sealed your room
