What it is

The Sime 5184817 fitting cocks kit is an isolation valve kit supplied for Sime gas boilers, listed under the 25 ECOMF NG valve kit reference. It provides the cocks used to isolate the gas supply to the appliance so that servicing, testing and component replacement can be carried out safely. The kit is intended for natural gas applications across a range of Sime domestic boiler families.

Signs this part needs replacing

  • The isolation cock weeps or leaks gas or water at the spindle or body.
  • The valve spindle is seized and will not turn, so the appliance cannot be isolated.
  • The cock will not shut off fully, leaving the gas supply passing when it should be closed.
  • Corrosion, cracking or deformation is visible on the valve body or connections.
  • A joint at the cock has been disturbed and will not seal reliably on reassembly.

Before you order

  • Confirm the boiler model and GC number against the fitment list above.
  • Check whether the appliance is the time clock or without time clock variant where this applies.
  • Confirm the appliance is natural gas, as this kit is specified for NG.
  • Check the existing valve arrangement on the appliance matches the kit before ordering.
