What it is

The Alpha 3.013387 seal kit is supplied for the heat exchanger and pump joints on Alpha gas boilers. It is manufactured by Alpha and used when the water-carrying connections at these components are serviced or repaired. The seals sit at the joints to keep water contained within the heat exchanger and pump assemblies.

Signs this part needs replacing

  • Water weeping or dripping from the heat exchanger or pump joints
  • Perished, flattened or hardened seals visible at the connections
  • Scale, corrosion or crusting around the pump or heat exchanger unions
  • Pressure loss or repeated topping up with no other obvious cause
  • Seals disturbed or damaged during a service or component change

Before you order

  • Confirm your boiler model against the fit list above
  • Check the GC number on the appliance data badge where one is shown
  • Note that the listed models are LPG variants
  • Confirm the kit is required for the heat exchanger and pump joints on your appliance
