What it is

The Ariston O-Ring D: 13.6MM X 2.7MM is a circular sealing ring measuring 13.6mm outside diameter with a 2.7mm cross-section. It is used to seal mating faces and connection joints on Ariston and Chaffoteaux gas boiler assemblies, preventing water or gas weepage at the joint. The part carries the manufacturer reference 61009834-18.

Signs this part needs replacing

  • Visible water weepage or staining at the joint the O-ring seals
  • The ring is perished, flattened, cracked or swollen
  • The ring has hardened and no longer sits proud of its groove
  • Signs of scale or corrosion debris trapped around the seating
  • The joint leaks after the assembly has been disturbed for other work

Before you order

  • Confirm the existing O-ring measures 13.6mm outside diameter with a 2.7mm section
  • Check whether the boiler is a pre-April 2006 or from-April 2006 build where the model listing distinguishes them
  • Inspect the groove and mating face for corrosion or damage before refitting
  • Verify the part reference against the appliance's own documentation where available
