What it is

This is the air inlet pipe O-ring, manufacturer part number 655996, produced by Potterton Commercial. It is a sealing component used on the air inlet pipe of Potterton Commercial Paramount series boilers. Its function is to seal the joint at the air inlet pipe, preventing air leakage from the combustion air path.

Signs this part needs replacing

  • Visible cracking, flattening or hardening of the O-ring material
  • Traces of soot, staining or debris around the air inlet pipe joint
  • Combustion readings drifting outside the expected range for the appliance
  • Audible air leakage or whistling from the air inlet pipe connection
  • The O-ring is missing, split or deformed when the joint is opened for service

Before you order

  • Confirm the appliance model and output match one of the Paramount Three, FOUR or FIVE variants listed above
  • Check the part number 655996 against the existing O-ring or the appliance documentation
  • Inspect the mating faces of the air inlet pipe joint for damage before fitting a new O-ring
  • Have the appliance combustion readings checked after any work on the air inlet path
