Joint de siphon De Dietrich 7700945

A siphon gasket is used to create a watertight seal in the siphon assembly of a boiler or heating system, preventing gas or water leaks. This component is typically found in condensing boilers where it helps maintain proper drainage and prevents backflow. Over time, the gasket may degrade due to heat and chemical exposure, leading to leaks or system inefficiency. Replacing a worn siphon gasket is a straightforward maintenance task that can restore proper function and prevent more serious issues.
