What it is

The Alpha 1.019643 is an O-ring seal measuring 11.90mm x 2.62mm. It is fitted at a joint or connection within the appliance to prevent water or gas escaping past the mating surfaces. It is listed for use on Alpha CD-series LPG boilers.

Signs this part needs replacing

  • Water or gas weeping from the joint the O-ring seals
  • The ring has hardened, flattened or lost its elasticity
  • Visible cracks, splits or nicks on the ring surface
  • Scale, corrosion or debris sitting on the ring
  • The joint continues to leak after being tightened

Before you order

  • Confirm your boiler model against the fit list above
  • Check the existing O-ring measures 11.90mm x 2.62mm
  • Check how many O-rings the joint requires before ordering
