present invention provides a better fireproof bulkhead penetration that is substantially less expensive to install and much easier to modify. The bulkhead penetration system is designed to prevent the spread of fire, smoke, water, gas and air through walls or bulkheads in both stationary and marine structures in way of piping and cable penetrations at the fire zone boundaries. Various preferred embodiments meet the requirements of the regulatory authorities having jurisdiction over the structure as well as the requirements of local authorities. In preferred embodiments a high temperature sealant provides an airtight seal for a sleeve type penetration and a high temperature sealant also provides an airtight seal between the sleeve and the bulkhead aperture through which the sleeve passes. The seals can be easily removed for repairs, upgrades and replacements.
