What it is

The Ariston 64990872 is a blue O-ring with a 13.94 mm inside diameter and a 2.62 mm cross-section, moulded in HNBR (hydrogenated nitrile butadiene rubber). It is a sealing component used on Ariston heating and hot water appliances, seating between mating surfaces to prevent leakage at the joint. It is supplied as a pack of three.

Before you order

  • Confirm the part number 64990872 matches the appliance documentation or the component being renewed.
  • Check the O-ring dimensions — 13.94 mm inside diameter and 2.62 mm cross-section — against the seal it is replacing.
  • Verify that HNBR is the correct material for the media and operating temperature at the joint.
  • Allow for the pack quantity of three where more than one seal is being renewed.
