What it is

The Worcester Bosch 8737602313 is a siphon seal used in the condensate siphon assembly of Worcester Bosch gas boilers. It sits inside the siphon or trap and forms the water seal that prevents flue gases escaping through the condensate discharge route. It is a direct replacement item for the seal originally fitted to Greenstar 2000 Combi and Greenstar 8000 Life Combi appliances, along with a wide range of other Worcester Bosch models.

Signs this part needs replacing

  • Water pooling or dripping around the condensate siphon or trap
  • Damp patches or staining on the surface beneath the boiler casing
  • A flue gas smell close to the condensate discharge point
  • The seal looking hardened, flattened or cracked when the trap is opened
  • A leak appearing after the siphon has been removed and refitted during servicing

Before you order

  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
  • Check the GC number or the serial plate on the appliance to confirm the model before ordering.
  • Compare the removed seal with the new one, as the siphon assembly can use more than one seal.
  • Quote part number 8737602313 or alternative number 2249284 when ordering.
