Hell-Sea is the world's first bulkhead and deck fire-tight passageway with thickness

inferior found on the market!


Hell-Sea was born from the need to adapt to the new safety regulations imposed by the various naval registers.

Developed by our team of expert engineers, it allows the passage of the exhaust pipes at high temperatures through the various rooms of the boat without compromising comfort and design.


Composed of fireproof and watertight materials, it guarantees high safety. It is made up of four metal half-flanges that compress a fireproof and watertight graphite packing. For this reason Hell-Sea is extremely easy to assemble and in case of need it can also be easily disassembled for any maintenance on the pipes.
