watertight and fireproof passage A60

Hell-Sea is the first bulkhead and deck exhaust fitting watertight-fireproof passage with the lowest thickness in the world!

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 experienced engineers, it allows the passage of exhaust pipes at high temperatures through the various rooms of the boat without compromising comfort and design.


Composed of fireproof and waterproof materials, it guarantees high safety. It consists of four metal semi-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 is also possible to easily dismantle it for possible maintenance on the pipes.
