Question Hehr window question

We're just back from a 3 week trip with our LiteHouse 4 Two, to the upper midwest. I was problem free except for a couple of annoying leaks. I found and fixed one leak (the vent hose had come off the water tank), and while I think I have identified the source of the 2nd leak, I'm having trouble finding the wisdom and parts to fix it.

The leak seems to be around the front (facing the back of the truck) "emergency exit" window. Water seems to be coming in there during heavy rains. We fixed it temporarily with some Gorilla tape, but I need to find a longer lasting fix.

The window is made by Hehr, and I suspect is one of their "Rockguard" windows. I'm assuming that the proper fix will involve removing and replacing the existing gasket, and perhaps, pulling, re-caulking and reinstalling the window.

My problem is that while I have found a bunch of companies which sell gasket materials, I can't figure out exactly what I should order. I can't find a link for spare parts on the Hehr site.

Does anyone have a suggestion of where I might look?

Thanks,
Davie

Davie, we recently removed our Hehr rear window which includes an emergency exit window sash on the driver's side. We have it disassembled and have ordered and received all of the seals. if you post a picture maybe I can help you figure it out.

Thanks John.

I think that the problem is with the gasket Iím pointing toward. Itís sort of foam and doesnít spring back when poked.

Where did you find the gaskets?

Also it helps if you can find the window model number. On our Hehr windows the model number is stamped on the top surface of the sill. Here is an example:

We bought a similar seal from Pelland Enterprises for our Boler 17. For the Trillium 4500 rear window that I mentioned earlier, we bought all of the seals from Vintage Trailer Gaskets, but that was a much different window design from 1978.

Generally the best way to do it is to remove the seal and examine the profile, THEN order samples to determine whether you found a match.

Also, have you checked with the trailer manufacturer?

Thanks John. That sounds like good advice. Iíll pull the window and get a better understanding about whatís going on.

Unfortunately, the manufacturer went out of business after building a very few units.

Well DW pointed out that even if the camper manufacturer were still in business, you would want to contact the window manufacturer for info re the seal.

I got back to this project today. There are two self adhesive gaskets, one on the inner window frame and one on the window itself.

The two gaskets press against each other when the window is closed.

Both gaskets are continuous and have an adhesive back.

The gasket on the frame is dry and cracked. The one on the window is better.

The gasket between the trailer shell and the window frame looks good and I cleaned the weep holes recently.

Iím going for the low hanging fruit and replacing the two adhesive gaskets first.

An update: I contacted the manufacturer who sent me to a company called Parkin. I sent them a small piece of each of the gaskets but they were unable to find a match. Iíve ordered a bunch of samples from VTS and hopefully will find something that works.

In the meantime, I have a question. Does anyone have a similar window (Hehr emergency exit window) in their camper, and if so, what kind of gaskets does it use?

Davie, we have an emergency exit window on our Trillium 4500. The only seal on it is a small y seal (Hehr part #009-289) on all 4 sides. Also, a header seal runs across the top. Here is a picture of it (the left half of the rear window).
