What it is

The Alpha 1.010334 is a sealed washer with a D.80 designation, meaning an 80 mm nominal diameter. It is a flat sealing component used to close off a joint or connection on Alpha heating appliances, preventing water from escaping past the mating faces. Washers of this type sit between two surfaces and compress under load to form a watertight barrier.

Signs this part needs replacing

  • Water weeping or tracking from around the joint the washer seals
  • Visible hardening, flattening or cracking of the washer material
  • Scale or corrosion deposits built up on the sealing face
  • A drip that returns shortly after a joint has been re-tightened
  • Discolouration or swelling of the washer after long service

Before you order

  • Confirm the part number 1.010334 against the number shown in your appliance's parts list or on the old component.
  • Check the D.80 diameter matches the joint being sealed, as washers of a similar type are supplied in several sizes.
  • Note the alternative numbers 1250002 and 010334 in case your documentation uses one of those references.
  • If the washer is being replaced as part of a wider repair, check whether any other seals or gaskets on the same joint also need renewing.
