Expansion vessel tube De Dietrich 710502300

The expansion vessel tube is a flexible or rigid pipe that connects the expansion vessel to the boiler's water circuit. This tube accommodates pressure changes as water expands when heated, protecting the system from overpressure. It is a critical part of boiler spare parts, often replaced during servicing to prevent leaks or bursts. A durable expansion vessel tube ensures the longevity and safe operation of your heating system.
