Expansion vessel hose G1/2 De Dietrich 7715661

The expansion vessel hose G1/2 is a flexible connector used to link an expansion vessel to the heating or water system. Featuring a G1/2 thread on both ends, this hose allows for easy installation and vibration isolation. It is essential for maintaining a secure, leak-free connection between the vessel and the pipework. Over time, hoses can degrade or become brittle, leading to leaks. Replacing it with this purpose-built hose ensures your expansion vessel functions correctly, protecting your system from pressure surges.
