Lewmar 360758999 Replacement Seal — New Standard Portlight, Size 0
The correct replacement seal for the Lewmar New Standard Portlight in Size 0 — the smallest size in the New Standard series, typically found on smaller cabin windows and portlights on sailboats and powerboats. This seal fits precisely into the portlight frame channel to create a reliable compression seal between the frame and the opening lens, keeping water where it belongs: outside.
Portlight seals are a maintenance item. Salt, UV exposure, and repeated opening cycles cause the rubber to harden, crack, and lose its ability to compress and seal. Replacing the seal is a straightforward repair that restores full weathertight performance without replacing the entire portlight assembly.

Parts Desk Insights
Size 0 is the smallest portlight in the Lewmar New Standard series and is the least common — typically found on smaller vessels or in tight cabin locations where a full-size portlight won’t fit. Before ordering, confirm the size number stamped or molded on your portlight frame, and confirm you have the New Standard series rather than the older standard or Ocean series, as seal profiles differ between series. For larger sizes in this same series, see the Lewmar New Standard Portlight Seal Size 1 and the Lewmar New Standard Portlight Seal Size 4. SKU: 239-360758999.
