The X5-Z5-Z6-Z7-Z9 280mm Reinforced Silicone Tube connects the Steam Thermoblock and
Ceramic Valve. It is the most common hose replaced in the Z-Line. Take extreme caution when removing the old hose and installing the new hose on the nipple of the ceramic valve.
The hose is secured by a metal clamp and collar connection to the plastic nipple, which requires decent pressure to secure. If you break the nipple, you will need to purchase a new ceramic valve.
