What it is

The gas cock is a gas isolation valve used on Johnson & Starley heating appliances. It controls the gas supply at the appliance, allowing the gas to be shut off for servicing, fault finding or safe isolation. It is listed for use across the Johnson & Starley Economaire and Hispec ranges.

Signs this part needs replacing

  • The gas cock will not turn freely, or is seized in the open or closed position
  • Gas is passing when the cock is turned to the off position
  • A gas smell is present around the valve body or its connections
  • Visible corrosion, damage or weeping at the valve
  • The handle or spindle is broken, so the valve cannot be operated

Before you order

  • Confirm the appliance model against the fit list above
  • Check the existing valve and its connections before ordering
  • Gas work must be carried out by a competent, registered engineer
  • Isolate and prove the gas supply is off before any replacement work
