What it is

The Ideal 003817 is a square head gas cock used as an isolation valve on the gas supply to commercial boiler plant. It is manufactured by Ideal and listed under part type isolation valves, with R1 1/4 x RC1 1/4 threaded connections. The valve sits in the gas train so the appliance can be shut off and isolated for servicing, commissioning or fault finding.

Signs this part needs replacing

  • A smell of gas around the valve body, spindle or threaded joints
  • The square head turns but the gas flow does not shut off fully
  • The spindle is stiff, seized or will not turn through its full travel
  • Visible weeping or staining at the spindle gland or connection threads
  • The square head is rounded or damaged so the valve cannot be operated with a spanner or key

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as Concord Super variants differ across series and orientations
  • Check the existing valve markings and thread sizes match R1 1/4 x RC1 1/4 before ordering
  • Note the alternative number 1170125 when cross-referencing older documentation
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
