What it is

The Ferroli gas valve outlet O-ring (E50) is a sealing component fitted at the outlet of the gas valve on a range of Ferroli gas boilers. It seals the joint between the gas valve outlet and the adjacent gas-carrying component, preventing gas leakage at that connection. The part is listed under Ferroli SKU 35100460.

Signs this part needs replacing

  • A detectable gas smell around the gas valve outlet joint
  • Soapy water test showing bubbles at the valve outlet connection
  • Visible cracking, flattening or hardening of the O-ring
  • Combustion readings drifting or unstable during service checks
  • Signs of weeping or staining at the gas valve outlet

Before you order

  • Confirm your boiler model against the fit list above before ordering
  • Check the gas valve outlet joint and O-ring seating during the service
  • Isolate the gas supply before any work on the gas valve assembly
  • Gas-carrying components must be worked on by a Gas Safe registered engineer
