Video: RV rubber care and maintenance


By Cheri Sicard
Rubber is all over your RV, both outside and under the coach. It’s in your tow vehicle, as well. But do you know how to care for your RV rubber parts? If not, the video below from Martin of RVstreet will show you how.

The sun’s damaging UV rays as well as engine heat are brutal on RV rubber parts and can cause them to deteriorate quicker. If you don’t address them early, they can create premature failure and can even cause RV leaks.

Even with these tips, it’s important to also note that with age rubber tends to break down.

Tools and supplies needed for the RV Rubber maintenance projects:

  • Thetford Premium RV Slide Out Rubber Seal Conditioner. According to the video, this stuff is the best. It contains a UV inhibitor and it conditions and softens rubber and prevents damage from UV rays. Martin uses it on almost everything EXCEPT tires.
  • A clean towel
  • Disposable gloves
  • A telescopic pole
  • An old sock
  • A ladder

Watch the video to see how this all comes together.

So what parts do they show you how to fix and maintain? A lot, including…

  • Rubber seals around the slide-outs on the interior and exterior—even if you have a topper on the outside of your slide
  • The rubber seals in the bay doors
  • Rubber seals around the entrance door
  • Rooftop vent seals
  • Rubber underneath the coach in the engine bay
  • All hoses in, around and under the engine and transmission area
  • Propane rubber lines
  • Windshield wiper spray hoses
  • Window seals and rubber parts
  • Hydraulic lines on your leveling jacks
  • Airbags

Take the time to do this maintenance once a year and your RV’s rubber will stay in top shape and last a long, long time.

One important note before you get to work: NEVER put any kind of conditioner or dressing on any of your belts such as engine belts, power steering belts, etc.

I work lubricant onto the back/underneath of the slide seals as well. Sometimes the seals seem to stick to the exterior slide wall if I don’t do that. Is that necessary?

I use Thetford at least twice yearly on all my rubber seals and hinges.

Glad to know you got it fixed. I could not imagine what would cause that.
