What it is
This five-piece O-ring set (SKU 7826216) from Viessmann seals the water pressure sensor on Vitodens gas boilers. The sensor is fitted to the hydraulic circuit, and the O-rings maintain a watertight joint at that connection. The set is listed in the Gas Boiler Spares range.
Signs this part needs replacing
- Water visible around the water pressure sensor connection or on the surrounding pipework
- Slow loss of system pressure that needs regular topping up
- Boiler showing a low water pressure fault or lockout code
- Perished, flattened, cracked or hardened O-rings when the sensor is removed
- Dampness or staining on the boiler casing near the sensor
Before you order
- Measure the existing O-rings. The product name lists 9.6 x 2.4, while the catalogue description gives 10mm x 2mm, so confirm the size against the seal being replaced.
- Check the boiler model and serial number against the fitment list above.
- Confirm the boiler was manufactured on or after 20.06.2007, as the listing applies from that date.
- Check that the set contains five O-rings before fitting, and keep spares in case a seal is damaged during removal.
