Schiuma Vent senza foro De Dietrich 7619793

Vent foam without hole is a sealing and insulating material used in boiler and burner enclosures to prevent air leaks and reduce noise. This foam block is designed for applications where a solid seal is needed without a pre-cut opening, allowing technicians to customize it for specific vent or access points. It helps maintain proper combustion air flow and contains heat within the system, improving efficiency. Suitable for use during boiler maintenance or when replacing worn gaskets, this foam withstands moderate temperatures and provides a durable barrier against drafts and debris.
