Tapón de purga 3 / 8» De Dietrich 300004141

The Vent plug 3/8" is a threaded plug used to seal vent or drain openings in heating equipment, such as boilers or radiators. The 3/8" size indicates the thread diameter, which is a common standard for many applications. This plug prevents air or water from escaping and can be used during maintenance or system flushing. Made from brass or steel, it is durable and resistant to corrosion. When selecting boiler spare parts, ensure the thread type (NPT, BSP, etc.) matches your equipment. A proper seal is essential to avoid leaks and maintain system pressure.
