What it is

The Alpha Hydraulic Assembly Seal Kit is a set of seals, O-rings, gaskets and washers sized for the hydraulic assembly on Alpha boilers. It is manufactured by Alpha and supplied under part number 3.022653. The kit seals the hydraulic assembly so that air, gas and water cannot escape from the appliance, keeping the system closed and reducing the risk of leakage.

Because these components are made to a specific size and thickness, they are particular to a given location within the boiler and are rarely interchangeable with seals from other positions or models.

Signs this part needs replacing

  • Water weeping or dripping from around the hydraulic assembly.
  • A drop in system pressure that cannot be traced to another component.
  • Visible hardening, cracking, flattening or swelling of the seals.
  • Damp staining or corrosion on nearby metalwork and pipework.
  • Air being drawn into the system, causing noise or poor circulation.

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the kit suits your model.
  • Note the alternative and previous part numbers listed below, as some appliances were built with earlier numbering.
  • Confirm whether the hydraulic assembly is being resealed or replaced, as the seals required differ by location.
