What it is

The Viessmann Gasket Set 17 X 24 X 2 (5 Pcs) 7826217 is a set of five gaskets from Viessmann, classed as a gasket, O-ring, seal and washer. It is listed for the gas connection pipe on Viessmann Vitodens boilers and is catalogued under Gas Boiler Spares.

Signs this part needs replacing

  • A gas odour around the gas connection pipe. Treat this as an emergency: isolate the gas supply and contact a Gas Safe registered engineer.
  • Visible gas or moisture leaking at the gas connection pipe joint.
  • The gasket is flattened, hardened, cracked or torn when the joint is opened up.
  • A gas tightness test fails at the gas connection after the joint has been disturbed.
  • Gasket material crumbling or deformed around the pipe joint during routine inspection.

Before you order

  • Check the GC number on the data badge against the listed GC numbers, such as 47-819-58, 47-819-55 and 47-819-56.
  • Confirm the serial range against the listing, for example VITODENS 050-W 35KW SERIAL No. 7968700.
