What it is

The Ferroli 30810850 is a 1/2 inch washer supplied for the CF4324 (K42) jig. It forms part of the sealing arrangement on Ferroli gas boilers, seating at a 1/2 inch connection to prevent leakage at the joint. It is listed under O-rings, washers and gaskets within the Ferroli boiler spares range.

Signs this part needs replacing

  • Visible weeping or dripping at the 1/2 inch joint the washer seals
  • Damp staining, corrosion or scale tracking around the connection
  • Washer hardened, flattened, cracked or deformed on inspection
  • Water or gas escape detected at the joint during service or a tightness test
  • Repeated loosening or re-making of the joint requiring a fresh seal

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the washer size required at the joint is 1/2 inch
  • Check how many washers are needed for the joint or joints being worked on
  • Isolate and depressurise the appliance before removing any sealed connection
