What it is

A Worcester Bosch flat seal, part number 8734954311, manufactured to the EN1514-1 standard for flat gaskets used in flanged pipework. It has a nominal size of DN 65 and a PN10/40 pressure rating, and is used to seal a flanged joint in heating or plumbing installations. The seal is a general sealing component rather than an appliance-specific spare.

Before you order

  • Confirm the part number 8734954311 against the appliance or installation documentation.
  • Check the joint is DN 65 nominal bore and that the PN10/40 rating is suitable for the system pressure.
  • Verify the flange faces and fasteners are clean and undamaged, as a flat seal relies on sound mating surfaces.
  • Check the standard and size markings rather than an appliance model alone, since this is a general sealing component.
