What it is

The Baxi 720633101 is a 3/8" to 22mm adaptor, a brassware fitting used to connect a 3/8" threaded or pipe connection to 22mm pipework. It is supplied by Baxi for use within their appliance and system pipework. The adaptor provides the mechanical transition between the two connection sizes, allowing pipework of differing standards to be joined at a single point.

Before you order

  • Confirm the appliance or system requires a 3/8" to 22mm transition, as both connection sizes are fixed by this part.
  • Check the part number 720633101 against the appliance's own documentation or component listing before ordering.
  • Verify the 3/8" end matches the thread or fitting it is intended to join; 3/8" formats are not interchangeable across all applications.
  • Ensure the 22mm end suits the pipe or fitting being connected, and allow for the correct sealing method at both ends.
