What it is

The Vokera 5036 is a pump union washer used on a range of Vokera gas boilers. It seals the union joint at the circulating pump, preventing water loss from the heating circuit at that connection. It sits within the Vokera O-rings, washers and gaskets range.

Signs this part needs replacing

  • Water weeping or dripping from the pump union joint
  • Staining, corrosion or limescale around the pump connection
  • The washer is flattened, hardened or cracked after the pump has been removed
  • System pressure dropping with no other visible leak
  • Damp patches beneath the boiler at the pump area

Before you order

  • Confirm your boiler model appears in the fit list above
  • Check the GC number on your appliance against the model listed
  • Confirm the part number 5036 matches the washer currently fitted
  • Check the washer is the correct seal for the pump union on your appliance
