Rear Sliding Window Gasket September 11, 2021, 04:05:49 pm While cleaning the interior windows and screens, I noticed daylight coming into the interior on the large, rear passenger side window. Looking outside, the sealing gasket has shrunk so there is now a good 1” gap. The driver side is shrunk also but not nearly as much as the other side. Should I be concerned at this point?
Re: Rear Sliding Window Gasket Reply #1 – September 11, 2021, 04:47:01 pm Although I am not familiar with 2017 models, I have never seen a pop-rivet on the outside of any window. Is it possible the PO had the side windows replaced with a different size, and some sort of filler was put in?Steve
Re: Rear Sliding Window Gasket Reply #2 – September 11, 2021, 05:32:56 pm Steve, I had to go outside and check. Turns out every sliding window is like that, including the small cabover windows. Looks like the rivets attach the vertical center metal pieces at the top and bottom.
Re: Rear Sliding Window Gasket Reply #3 – September 11, 2021, 06:21:12 pm Greg, there was so much light coming in I misinterpreted its source. So it is just the receding channel cover in the bottom that has a gap? Is there a brush-like sweep vertically in the rear edge of the fixed window? I wonder if this change occurred due to a switch away from the Hehr windows. If so, it could be the channel cover shrinks more than previously used. If you pull out enough to ID the cover, you could replace it - or, just get a small amount, re-insert the old one to fill in the gap, then add a small piece at the top where it is less noticeable.Steve
Re: Rear Sliding Window Gasket Reply #4 – September 11, 2021, 07:24:32 pm Greg, seal “shrinkage” is not uncommon; I think it’s most likely due to stretching the stuff when applying, , particularly around corners, and not allowing sufficient to cover the entire track.Try Custom RV Windows, RV Entry and Baggage Doors, RV Tanks, RV Shower Pans - RV... go to “RV Window Seals and Tracks” and look at the first product: H109-376. I used this on my 2003, and I’m pretty sure that it’s the same for your 2015. Maybe get 1’ to test the size, *or*, remove the original strip from around the window, clean it and the track, and replace the strip without stretching. I’d start at the top center of the frame, so if there is a gap when you finish, it will be at the top of the frame. 2 Likes
Re: Rear Sliding Window Gasket Reply #5 – September 11, 2021, 08:13:41 pm Would it be possible to clean the gap up and fill the opening with black polyurethane like they use on windshields. The gasket appears to have been calked once, probably in manufacture. Jon
Re: Rear Sliding Window Gasket Reply #6 – September 11, 2021, 08:24:39 pm Thanks, Joan! I pulled the gasket out a little to measure and I think you hit the nail on the head. Think I'll order a foot to verify the size. I can probably just fill it in with a short piece as Steve suggested. My understanding is that this gasket doesn't seal the window to the frame so I don't think it's a huge problem but the gap is allowing weather to possibly get inside. Maybe I can just run a bead of sealant into the gap if I can't get it taken care of before our trip in a couple weeks.

I think it's just held in by friction to the channel but not sure. I'm sure this is old hat to many of our members but new to me.
Re: Rear Sliding Window Gasket Reply #8 – September 11, 2021, 09:23:48 pm The strip is not caulked; it fits into the grooves in the frame. It’s easy to miss aligning and fitting in the strip into the frame; LD did a sloppy job of fitting on the rear window replacement of my rig. I advise making sure that the track and the “gasket” strip are clean and working carefully to make sure that the notches and ridges of the frame mate well to the stripping. 1 Likes

Re: Rear Sliding Window Gasket Reply #11 – October 25, 2021, 05:22:08 pm Thanks, Joan and Larry. I ordered a foot of new gasket from Pelland (their minimum amount), then pulled off the old gasket (which is in good condition) from both rear sliding windows and reinstalling it, as suggested, with the gaps on top. A foot of material was more than enough to do the job.

Re: Rear Sliding Window Gasket Reply #13 – October 17, 2022, 08:30:02 pm For what it’s worth, I simply removed that piece, cleaned it and reinstalled it. It has the ability to shrink and stretch. I did this about 4 years ago and everything has remained in place. Whatever you do, don’t fill that space with anything. Hope this helps.
