أنبوب مفتاح الضغط (x4) (4 رطل لكل بوصة مربعة) De Dietrich 7869617

This set includes four pressure switch tubes, essential for connecting pressure switches in boiler and burner systems. Pressure switches monitor air or gas pressure to ensure safe combustion, and the connecting tubes must be flexible and airtight. These tubes are typically made from silicone or rubber to withstand heat and pressure fluctuations. Having a set of four allows you to replace multiple tubes during maintenance or keep spares on hand. They are common spare parts in heating equipment, ensuring accurate pressure readings and safe system operation. Check the inner diameter and length to ensure compatibility with your specific pressure switch and boiler model.
