This square deck filler in mirror-polished AISI 316 stainless steel is the WASTE variant of the SQUARE series. The short model is intended for a marine waste or sewage tank system and has a nominal neck/hose connection of Ø38 mm.
The deck filler features a flip-top opening, allowing the deck fitting to be opened without a traditional loose screw cap. The square top has a thin 3.5 mm profile, providing a low-profile transition to the deck. The top dimensions are 60 × 70 mm.
The construction is made of AISI 316 stainless steel with a mirror-polished surface. The WASTE marking identifies the connection as access to the sewage or septic tank system, distinguishing it from the series’ variants for water and fuel.
For connection to land-based pump-out or emptying equipment, the separate adapter with item no. 20.866.91 can be used. The adapter has 1 1/4" BSP thread with a stated thread diameter of 41.90 mm and is documented as compatible with this deck filler. It is this adapter solution that is used for the ISO 8840 connection; the deck filler alone is not documented as ISO 8840 certified.
