What it is

This is a Baxi O-ring, supplied under part number 5120477 and listed for the by-pass screw. The O-ring has a stated size of 7,65 x 1,78 mm. It is a small sealing component used to prevent leakage at the by-pass screw joint within the appliance's water circuit.

Before you order

  • Confirm the part number 5120477 matches the component currently fitted or listed for the appliance.
  • Check the stated O-ring dimensions, 7,65 x 1,78 mm, against the groove or sealing face on the by-pass screw being serviced.
  • Verify that the by-pass screw removed from the appliance is the type that uses this O-ring, as assemblies vary between models.
  • Consider holding a spare, as O-rings are easily pinched or lost during reassembly.
