What it is

This is a Viessmann O-ring with a measured size of 19.8 x 3.6 mm, supplied as a pack of five under part number 7831415. It is a sealing component used within Viessmann gas condensing appliances to prevent water or gas weeping at a joint face.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the O-ring material
  • Water weeping or a damp trail around the joint the O-ring seals
  • Persistent pressure loss traced to a sealed connection
  • A smell of gas or a detected leak at a joint face after disturbance
  • The O-ring has been re-used after a joint has been opened and it no longer sits proud of its groove

Before you order

  • Confirm the existing O-ring dimensions match 19.8 x 3.6 mm before ordering
  • Check the appliance model and serial number against the fit list above
  • Verify the Viessmann part number 7831415 matches the part being removed
  • Consider whether a pack of five covers the joints being worked on
