What it is

The Sime 6028643 Air Diaphragm Diam. 27 JIWL- is a flue assembly component for Sime gas boilers. Its catalogue classification is flue assembly, so it forms part of the boiler's flue and air system rather than a standalone fitting. It is supplied as a 27 mm diameter diaphragm.

Before you order

  • Confirm your boiler model and its GC number against the fit list above.
  • Check the existing diaphragm's diameter matches 27 mm before fitting.
  • Note the LPG variants listed, if your boiler runs on LPG.
