What it is

The Worcester Bosch inlet adaptor, part 87161064390, is a connection component that sits at the water inlet of the appliance and joins the incoming supply pipework to the internal hydraulic assembly. It is manufactured by Worcester Bosch for use across the British Gas and Greenstar appliance families. Its function is to hold the inlet connection secure and correctly aligned so that water enters the unit at the intended point and flow through the appliance stays stable.

Signs this part needs replacing

  • Water weeping or dripping from the inlet connection while the appliance is running or filling
  • Visible corrosion, cracking or heavy scale build-up on the adaptor body
  • Reduced or erratic flow into the appliance at the inlet
  • A joint that will not seal after the connection has been remade
  • Water staining or damp patches on the casing below the inlet area

Before you order

  • Check the GC number or the serial plate on the appliance against the compatibility list to confirm the correct fitment.
  • The alternative part number 1014913 may appear in place of 87161064390 on older documentation or parts listings.
  • Inspect the inlet connection for a gasket or seal that may need renewing at the same time as the adaptor.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
