Hello all,

I just have to say that I'm pretty impressed with the way URO door seals fit. URO=$40 and OEM=$250+, so I was surprised such an inexpensive seal fits so well. I wouldn't use URO for a critical part but for a door seal, why not?

I did the following:

-removed the old seal, it crumpled into pieces upon removal
-kept all the clips (4 clear and 1 black)
-cleaned up the old factory glue/weatherstripping adhesive - using "Goo Gone"
-rinsed everything down with a micro fiber cloth and some light water
-dried it, applied new seal carefully around the door, started with the clip area
-applied some new weatherstripping adhesive at the bottom, let it dry and cleaned up the area where adhesive got

It's so quiet now! Absolutely night and day difference. It's slightly harder to shut the door now but I'm hoping that changes in the coming weeks!

Interesting. I need to replace all mine. Especially the drivers door. I had been thinking of using OEM from the dealer for that one and URO for the rest as they are almost never opened and I can't shell out a grand for rubber.

I put Uro door seals on my last W123 and you always had to slam the driver's door shut and the rubber pushed up in places where it should not have. Slamming the door never went away. I wish I had never done it.

That would be my recommendation as well as trying to repair the existing rubber if possible. Mine have guerrilla tape covering the cracks and it is nearly unnoticeable.

Dkr.

My aftermarket seals do the same thing. Have to slam the doors. It’s a bit better now 2 years later.

Thanks for sharing. Good to know what is out there.

I never liked the URO quality of the last few things I bought. The windshield seal for my 123 was not as thick as the OEM one. But it works.

As time has gone on I'm actually grateful URO is servicing this market. Their parts for the most part (not always, sometimes I have to dumpster their stuff) work and it beats the heck out of NLA.

The fact we can get door seals for a 35 yo car is amazing. I wonder if these cars will evolve into the status of a tri fives chevy in time, then we'll get remanufactured parts cheap from a catalog company like National Parts Depot.

Or will they just disappear...,

Mine is too far gone. If it rains or I wash the car there is a six inch gap in the seal where it's crumbled away. I get a shower of water coming in on my left shoulder. I've patched it by fixing a lenght of the kind of foam rubber seal you use to insulat AC lines which has a sticky underside to attach around the pipe. When the door closes it conformed to the shape of the hole and works ok for now. But a proper replacement is required.

I guess I'm lucky. I purchased my door seals about twenty years ago from the stealership. I just noticed the pricing on door seals from mercedes has gone THROUGH THE ROOF!!!!

I can't emphasize this enough - URO seals don't come close. They are fundamentally different in dimensions, quality of rubber and are typically replaced with OE seals once the poor sod who buys them figures this out.

I have TruckTec which I am now installing. I am surprised by their quality. Fit perfectly, at least the rear driver side. I have to finish up and move onto the next one. However, at $30 bucks each I am super happy thus far.

Strange, we sell about 275 of each side front seal annually with a total of 3 returned as "defective" in the last twelve months, and about 150 of each rear side annually with only one returned as defective in the last year. We'll have the engineers check it out though, and compare current stock to our OEM samples.

For 1985 300D:
123 720 1578 Front Left
123 720 1678 Front Right
123 730 0178 Rear Left
123 730 0278 Rear Right

Impressive. While you're chatting with the engineers, thought I'd share a list of parts that thousands of /8 owners will not be able to purchase anywhere, incase there is interest in URO filling that demand. Mercedes confirmed NLA with no supply anywhere and no other aftermarket manufacturers.

Industrial Rubber

Hello URO support, I will say I am happy you are supporting the industry I have had poor luck with door seals and window seals from üro.

Front windshield seal wasn't even fully cut to fit the glass so I threw it away and door seals for both front doors were too long and I actually needed to cut sections out to get them to fit and lived with the occasional wind noise for a few years until I recently purchased genuine MB seal.

If you've improved quality then fantastic otherwise I have not had great luck.

Same here. I'm re-doing my sunroof right now. About 10 years ago, I was in the same situation with another W123 and bought front and rear Uro seals. I'm going to be paying quite a bit to source NOS OEM seals this time.

My Mercedes mechanic who has worked on these cars since they were new broke two of the rubber seals trying to install them and finally got the third one in, but the lip wouldn't seat properly as it was too big. The dimensions and quality of the rubber simply wasn't right.

It would be nice if Uro upped their game in terms of quality. I would be willing to pay twice as much to get seals that just fit properly. Many of the people who put these parts on their cars want something that will last long term. Mercedes cars are harder to work on than domestic cars and I don't want a part that will need to be replaced in a few years.

Dkr.

That may be the case, however many of the owners are probably just leaving the part installed (despite being unhappy with it) because they don't know what other parts to use.

Dkr.
