Goiot tradition port gasket size

[CHM]

I cannot seem to find this elsewhere. Anybody know the diameter of the gasket use on these ports? My boat is late 80s Oceanis 430. I think it's 10mm, but need to make sure. Thanks.

I did the ports with EPDM rubber got it from Select Plastics stopped all the leaks was an easy job. Select Plastics will also rebuild hatches.

I think they are in CT but maybe MA

Think the gasket was just 3/8" round (9.5mm)

Here they are http://www.selectplastics.com/

1985 bene with Goiot ports so sounds similar to your boat

Thanks. I thought a 3/8 would work. I wasn't sure if it was 8 or 10mm. I think its closer to 10.
