What it is

The Alpha 1.1342 is a flat washer gasket measuring 34mm outer diameter, 27mm inner diameter and 2mm thick. It is fitted to Alpha gas boilers and solar thermal cylinders to seal a joint between mating faces. The Flexoid gasket material compresses under load to close the gap and prevent water escaping.

Signs this part needs replacing

  • Water weeping or dripping from the joint the washer seals
  • Limescale trails, damp staining or corrosion around the mating faces
  • The washer has flattened, hardened or cracked with age
  • System pressure drops or water loss traced to the joint
  • The washer is deformed or torn after being disturbed during other work

Before you order

  • Measure the old washer: 34mm outer, 27mm inner, 2mm thick
  • Confirm your appliance model against the fitment list above
  • Check the mating faces for pitting or scoring that could prevent a seal
  • Check whether the joint uses more than one washer
