Coupe Window Door Seal Question

Are these gaps in my door seals caused by age and the rubber shrinking? I'm not so concerned with water getting into the car as the car isn't driven in the rain, unless caught in it, but when the windows are closed there is obviously a good amount of noise from air leaking around the gap.

And I know the rubber on the coupes isn't cheap at around $500.00 each for the door seals and close to $2500 to $3000 to replace all the rubber on the doors/windows, but the car will get what it needs. Any aftermarket company making the coupe window seals? I know nothing beats original MB rubber when compared to aftermarket, but for the money I may be willing to try some other brand, except URO.... I went down that route on a W126 chassis and would not spend my money on URO seals ever again.

The gaps are due to repeated heat-cool cycles, UV light exposure, lack of care, and chemical degredation.

"Any aftermarket company making the coupe window seals?"
I do not know.

Part numbers for the various seals. Right around $1,800.00 depending on what I need.

How badly worn/cracked are they? You can remove them and glue the first two together.

They are bad enough that I think they are beyond saving. Fortunately it seems the only ones that are really bad are the ones around the top of the door frame where the window seals, unfortunately these are the most expensive ones. I think the others will respond well to a very liberal does of Protectant 303.

Post W123 Coupe Fun

I recently was told my the M-B Classic Center that these seals are N.L.A.

There's a guy in Israel who sells these and other Coupe rubbers, not uro (crap) brand .

I'm sure that in rust prone TAXachusetts (when I'm from) there are some rusted out W123 coupes you can buy this used rubber from and ever so carefully cut and glue one longer one to make up for the gap that's caused by age shrinking .

There is a kid in Orange County , Ca. who breaks W123's to spares, last Summer he got in a nice blue coupe that was broadsided , he may have the rubbers and he's very affordable, I don't know his name / contact info though.....

Don't give up / despair ~ this is the normal sort of thing all oder car enthusiasts (nutters) deal with, I got that annoying whistle to quit on my car, so can you .

Any idea on who the guy in Israel is and how to get in touch with him? Or more info on the Orange County kid? The issue is not that many coupes were made and anything used is going to be 30ish years old. The on-line MB stores still show them being available???

Many online retailers, including those fronted by M-B dealerships, knowingly list many parts that are not available. In this respect, some are worse than others. The practice has gone on for many years.

Post W123 Coupe Window Seals

M-B Classic Center can't get them anymore so don't waste too much time asking .

find the correct part numbers (L & R are different, dig) then search E-Bay.de as lots of oddball things pop up in Germany .

I found the guy in Israel by looking for W123 in E-Bay ......

Good luck hunting .

Try calling the Mercedes-Benz dealership up in Anchorage, Alaska. They have a lot of old stock on the shelves. I used to be blown away with the unobtanium I would find there.
