What it is

This is a Potterton O-ring with dimensions of 33.05mm x 1.78mm, supplied under part number 5132328. It is a sealing component used on Potterton Commercial Sirius boiler appliances, where it forms a watertight joint between mating surfaces. The O-ring is a service part intended for replacement during maintenance or repair work.

Signs this part needs replacing

  • Water weeping or seeping from the joint the O-ring seals
  • Visible hardening, flattening or cracking of the ring
  • Discolouration or perishing of the rubber material
  • Persistent small leaks after the surrounding components have been checked
  • The O-ring is disturbed or damaged when a joint is opened for service

Before you order

  • Confirm the appliance model and that it appears in the fits list above
  • Check the existing O-ring dimensions against 33.05mm x 1.78mm
  • Verify the part number 5132328 against the appliance's documentation or the component being replaced
  • Examine the surrounding seals and joints, as more than one may require renewal at the same time
