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.

It's not quite that simple... ...to replace, but it works and seals everything up again. )

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.

This is not the correct seal; it is incompatible.

The rubber is to thick and won't allow the window to close.

The rubber seal is to fatthick to allow the window to close and binds with the hinges too. Since it comes in bulk I was able to cut a couple of trial pieces and really play with it and see how well it would dry fit. Using just a small piece I could close the window but the larger the piece I used the hard it was to close until it was cut to size and the window would not close at all.

Reply from LEWMAR

It may happen that the portlight doesn't close properly with a new seal.
In this case, install a spacer under the portlight closure holder.
The new rubber seal will be hard and not yet in the correct shape. After a short time and
several openings and closings, the seal will return to its normal shape, and you can remove the spacer.

I have an Lewmar Atlantic 32 (oval). Will this seal fit such a porthole?

Please contact [email protected] and ask for º 360066995 Seal Atlantic Port 5m (up to 8weeks) º 360066999 Seal Atlantic Port 10m (on stock) FYI - AT PL Sz32 CUT LENGTH 820mm You will need to trim to length and join. The glue used to join the ends is cyanoacrylate (sometimes known as superglue or crazyglue). Hope this helps.
