This gasket for Lewmar Flush Hatch 2G is a size-specific spare part for size 44 deck hatches. It is intended for Flush 2G hatches produced from 2006 onwards and is used to restore proper compression and sealing between the hatch frame and the glass/lid.
A worn or compressed hatch gasket can lead to water ingress, drafts, or rattling. The gasket is shaped to fit the frame profile and compression requirements of the compatible size 44 hatch. The sealing material is developed for marine use with resistance to UV, saltwater, and repeated compression.
The gasket is not universal and must be selected based on hatch profile, generation, and size. It fits the Lewmar Flush Hatch 2G size 44 and should not be confused with gaskets for Low Profile, Medium Profile, Ocean, or Flush Hatch 3G models. The compatible size 44 hatch has external dimensions of 512 × 512 mm, an installation cutout of 442 × 442 mm, a corner radius of 42.5 mm, and a total depth of 31 mm. These dimensions describe the hatch and not the gasket itself.
Lewmar's spare part number for size 44 is 361591999. For the same hatch size, separate acrylic/plexiglass is also available under item no. 19.914.44. Always verify the hatch series, generation, size, and original spare part number before purchasing.
