The Vaillant 106563 is a genuine OEM packing ring (seal) designed for use in selected Vaillant boilers and heating components. This high-quality sealing ring ensures an airtight and watertight connection between key hydraulic or combustion parts, helping maintain system pressure, prevent leaks, and support safe, efficient boiler performance.

Over time, seals can become worn, flattened, or degraded due to heat, pressure, and general operation. Replacing them with genuine Vaillant components ensures proper fitment, long-term durability, and continued reliability.
