This seal kit for Lewmar Flush Hatch 2G is a genuine replacement seal for deck hatches in size 70. It is precision-fitted to the hatch frame profile and compression seal, and is used for Flush Hatch 2G hatches produced from 2006 onwards.
The seal restores the correct compression between the acrylic lid and the frame, ensuring the hatch's weatherproof and watertight closure is maintained. Replacing a worn or permanently compressed seal can reduce water ingress, drafts, and rattling, as well as contribute to smooth operation of the hatch.
The seal kit is made of EPDM, which is designed to withstand UV exposure, saltwater, and repeated compression. On the Flush Hatch 2G, the seal is mounted on the acrylic lid/panel. The seal is specific to size 70 and is not a universal seal for other hatch sizes.
The compatible Flush Hatch 2G hatch in size 70 has external dimensions of 697 × 697 mm and a deck cutout of 627 × 627 mm with a 42.5 mm corner radius. The overall depth of the hatch is 31 mm, and the acrylic thickness is 15 mm. These dimensions can be used to identify the hatch and do not describe the dimensions of the loose seal.
The Lewmar manufacturer part number is 361593999. Verify the hatch series, size, and manufacturer part number before ordering, as the Flush Hatch 3G uses a different seal placement and separate seals. Other documented spare parts for the Flush Hatch 2G size 70 include acrylic panel 19.914.70, locking handle kit 19.910.11, hinge 19.915.03, frame connector 19.915.04, and hatch stay 19.915.05.
