What it is

The Alpha 1.026455 is a red silicone O-ring measuring 9.19 mm x 2.62 mm. It is a sealing component used within Alpha gas boiler assemblies, including the InTEC and Commercial PRO TEC ranges. Silicone is chosen for its heat resistance and ability to hold a seal across the temperature swings seen in boiler components.

Signs this part needs replacing

  • The O-ring has hardened or gone brittle with heat cycling
  • Visible cracking, splitting or a flattened cross-section
  • Weeping or a damp trace at the joint the O-ring seals
  • Discolouration or a burnt appearance on the silicone
  • The O-ring is missing or has been lost during a strip-down

Before you order

  • Confirm the part number 1.026455 against your appliance's parts list
  • Check the model against the fitment list above before ordering
  • Measure the old O-ring to confirm the 9.19 mm x 2.62 mm size
  • Check how many O-rings the job requires, as more than one may be used
