What it is

The Baxi 242520 is an O-ring, classed under gaskets, O-rings, seals and washers, supplied by Baxi. It is a 15.54mm internal diameter by 2.64mm cross-section seal, used to create a watertight or gastight joint between mating boiler components. The catalogue listing describes it as a Bermuda nitrile O-ring.

Before you order

  • Confirm your boiler model and serial number, as several listed models are specific to serial number ranges.
  • Measure the existing O-ring's internal diameter and cross-section and compare with 15.54mm x 2.64mm before ordering.
  • Check the appliance's installation or service manual to confirm the O-ring's location and position.
