My installer is ordering a Porsche OE seal and I'll head over there and we'll decide on which seal to go with. He's skeptical about Uro offerings. We'll see. I'm pretty pissed off about the quality and price of Porsche OE parts (which are no better than reproductions) anymore.

URO products can be hit or miss. Some great...some not so much.
I'm about ready to put a new windshield gasket in the car.
Watching this thread with interest.

This seal worked great
 

So my '74 project was ready for the windshield today after many years of work. Put the new seal on the new glass, inserted trim (with soap and water), roped the window to start at the bottom center and work out and around the edges equally. Did it by myself worked great the first time. The extra width of the seal really seals good. Good job Uro on this one.

Awesome, thanks for the update!

After multiple attempts at installing my new Porsche windshield with the factory gasket I finally decided to try the new URO gasket after reading this thread.

I could never get the Porsche gasket to seat properly and stay over the metal lip, even with 3 of us doing the install. The URO gasket slipped in perfectly with the first attempt and it does an excellent job of filling the gap between the trim and the body. It also extends over the headliner clips and lower windshield opening metal better than the Porsche gasket. I should have started with this gasket in the first place. This gasket fit perfectly on my '87 coupe. See the attached photos.

Save yourself a lot of work and money and just start with the new URO gasket. I really appreciate the help and information everyone provided here.

That's good to hear that your URO gasket worked so well.

~4 hours later (the VAST majority of which was cleanup of the existing urethane windshield adhesive/ sealant) and the new windshield + Üro seal are in.

As per usual, it's all about the prep as the actual windshield install took two of us less than fifteen minutes.

As Wasatch 911S said, the Üro seal does a good job of fitting over the windshield frame pinch weld flange, both inside and out, including filling the perennially ill-fitting top corners.

This seal does seem to be a great alternative to OE or OEM units. The unit fits well and is affordably priced. What remains to be seen is how durable the unit will be, how long it will remain pliable, etc. Obviously, only time will tell.

Now that we're in 2025 is there any update on the updated real seal?

Thank you

Thanks for asking GSixZero! Unfortunately the redevelopment cost for Rear Window Seal 911 545 225 00 turned out to be too high given the current offerings from competitors, and we've discontinued the part number. Sorry for the bad news...

Ugh. Bummer. Sorry to hear that.


Elsewhere, this thread...

...got me wondering:

How many of us, that have installed this latest Üro front seal, have subsequently needed to adjust the top corners via the block of wood / mallet method?

I'll go first...
I have not. The corners appeared to fit well upon initial windshield / seal install.

I started this thread in Nov ‘22. Happy to report that I haven’t had to do any adjustments with a mallet and that the Uro seal fits as well as it did on day 1. I haven’t noticed any deterioration in the rubber but my car is garaged and I regularly treat all rubber seals/trim with a marine-grade protectant.

Mine fit perfectly with no adjustments. It has only been 4 months, but no shrinkage or leaks. As mentioned before getting the trim to match the opening before you place in the gasket is key.

Sad to hear but understandable. Thank you for the effort and the replies. I was able to track down an older one in stock

Following the reviews here, I chose the new Uro seal for my windshield install. Overall it looks good and the install went fine. I like that the new seal is wider than the factory seal, except at the top where it protrudes beyond/doesn't sit flat against the leading edge of the roof.

Anyone experienced this too? The glass and trim are nicely seated so I'm not sure there is any solution.

Bummer.

Per my pics above, fit was excellent and has remained that way ever since.

Hopefully @UROParts can intervene/ assist.

My guess is that the shape of your trim was not perfect when you installed the windshield. Unfortunately the fix is to pull it back out, pull the trim out of the rubber and fit the trim to the car. Then "installation is the reverse"..... I just went through this on my car. I also used the URO seal and can say after the second attempt, it now fits perfectly and went in like butter. To remove the windshield you can lift up an edge of the seal on the inside of the car, you should be able to slip it off of the pinch weld and then just push (gently) around the entire glass perimeter working the seal off the pinch weld. You can reuse the seal. When I fit my trim, I actually clamped it to the car and worked around the entire windshield opening getting the trim as close as I could to the pinch weld in all 3 dimensions. It took a few hours as my trim was old but once I did that, everything fits perfectly.

Thanks for the tip. I spent quite a bit of time working on the trim (new from Porsche) and was satisfied with the shape before it went on the seal and car.

So the trim sits nicely, the only thing I could have done better was the top edge: on installation the seal didn't overlap the upper pinch weld by more than a few mm. I was able to carefully adjust this after installation on the car by tapping the trim and gasket upwards towards the roof with a block and mallet (there are threads on this technique.) This made no difference in the issue above, however.

I can of course adjust the trim and seal even further outwards on the top or start over, but I'm not sure that will make a difference based on what I have already done. Not doubting your suggestion, just trying to figure out what I could have done better.

Looking more closely at the outside, it is almost as if the windshield, seal and trim sit just a few mm too far into the window opening. A trim adjustment won't do anything about that, and looking at the seal on the upper pinch weld from the inside it is now placed nicely-- not supporting what I'm seeing on the outside.

I really appreciate the tips. Worst case I'll just re-do it SmileWavy

I'll add to this thread from recent experience. We tore two Genuine Porsche seals trying to reinstall the front glass on a 79 SC this week. I finally convinced them to try a URO seal and it went right in.

I'm still thinking your trim is off in the 3rd dimension (in/out of the pinch weld). I had a corner that looked similar and the problem was the trim wanting to sit too far out from the weld. The good news is I'm now very experienced at putting in 911 windshields. I hope I'm wrong!

Only speculation at this point, but...

Can you post some pics of the the overall position of the window and the lower edge positioning (inside too if possible). At first glance it looks to me like the window is setting too low in the frame. This may also account for the lack of overlap on the upper pinch weld.

I'd guess from the shape of the seal that if you were to be using the factory seal the entire upper run would have dropped into the frame recess, which would make this much more obvious, where the URO seal helps mask it with the extended lip.
