حشية باب مقاوم للحريق من طراز BOB من De Dietrich 7311320

The BOB fire door gasket is a sealing component designed specifically for BOB boilers or burners. It creates an airtight seal around the fire door, preventing combustion gases from escaping and ensuring efficient operation. Over time, gaskets can wear out, leading to leaks and reduced performance. Replacing the gasket with this genuine-style part restores proper sealing and helps maintain safe and efficient heating. It is a common maintenance item for BOB equipment owners and technicians.
