What it is

The Alpha 3.022652 is a complete seal kit covering the water and gas joints on Alpha's domestic boiler range. Alpha supplies it as a single service item, so an engineer can renew every gasket, O-ring, seal and washer on the assembly in one visit instead of ordering individual seals. It is used across the Alpha ECO and INTEC families, among other models.

Signs this part needs replacing

  • Weeping or dripping at joints on the water side of the boiler
  • A smell of gas, or a failed tightness test around the gas valve or burner assembly
  • Seals that have hardened, flattened or cracked with heat and age
  • Repeated pressure loss with no visible leak elsewhere on the system
  • Water staining or corrosion around a joint noticed during a service

Before you order

  • Check the GC number on the appliance data badge against the compatibility list before ordering.
  • Confirm part number 3.022652, or one of the alternative numbers 1258399 or 022652, on the old component or the service paperwork.
  • The kit covers both water and gas joints; where only one joint is being renewed, check whether a single seal is the better match.
