Roxtec Sleev-it™ waterproof penetration seal

Penetration seal for plastic pipes for basic protection against gas and water.

The Roxtec Sleev-it™ Waterproof penetration seal for plastic pipes consists of a stainless steel casing containing layers of intumescent material that react with the heat of a fire to protect the penetration once the pipe begins to soften. The rubber grommet is sized per specific pipe size and designed to maintain a waterproof seal round the plastic pipe. The transit is welded to decks or bulkheads without additional sleeve.
