Almost like the original I'm satisfied; it's not too difficult to install. It's a bit difficult the first few times. But after a week, it's back to normal...

Fits perfectly It fits well, and the instructions are clear. You need to thoroughly clean the silicone from the gate frame before installing the new seal, especially on the curves.

Received today and still needs to be assembled I bought this seal by the meter to replace my LEWMAR side porthole seals. The seal's profile isn't exactly the same as the original one, which dates back to 2003. That one was a simple lip that made contact between the plexiglass and the frame when closed. This one looks more like a thicker bead that compresses when closed. The previous seal hardened with age and eventually lost its watertight seal. With this replacement model, that shouldn't be a problem. Now I just have to install it. The instructions are clear, and the reviews I've read show that with patience and a bit of skill, it's doable. Now I just have to get the job done.

Easy to process
The seal fits well and is easy to work with. I spot-bond the seal with Sika 295UV.

Seal for Lewmar Portlight porthole
The seal I bought is a 100% match for the original. Since it's the same thickness as a new seal, I applied a little silicone spray to make it slide more easily when closing. I left them closed for four days, and after that, my wife was able to open and close them as well. Before that, it was too difficult for her. I thoroughly cleaned the groove before installing it, which is why they fit so well.

The glue used to join the ends is cyanoacrylate (sometimes known as superglue or crazyglue). Hope this helps.
