حشية الباب الأمامي 170x17x2 De Dietrich 7774188

A front door gasket measuring 170x17x2 is a sealing component specifically designed for the front door of a boiler or burner unit. This gasket prevents the escape of flue gases and maintains the pressure inside the combustion chamber, which is vital for efficient operation. When replacing worn gaskets during boiler maintenance, using the correct size ensures a proper seal, reduces heat loss, and enhances the safety of your heating system.
