Przepust kablowy 300x350x20 De Dietrich 7731673

The grommet 300x350x20 is a protective rubber or plastic component used to seal and cushion openings in heating equipment. With dimensions of 300mm by 350mm and a thickness of 20mm, this grommet is suitable for larger panels or enclosures. It prevents vibration, reduces noise, and protects cables or pipes from sharp edges. Commonly used in boilers, burners, and other heating appliances, a worn or missing grommet can lead to damage or inefficiency. Replacing it ensures a proper seal and extends the life of your equipment.
