What it is

The Hamworthy 1 inch flow pipe gasket is a sealing component for the flow pipe connection on Milborne wall hung condensing boilers. It is manufactured by Hamworthy under part number 573407238, with the manufacturer reference GUARN030. The gasket seals the joint between the flow pipe and the boiler connection, preventing water loss at that point.

Signs this part needs replacing

  • Visible water weeping or staining around the flow pipe connection
  • Damp or corroded pipework or casing local to the joint
  • A weeping joint that persists after the connection has been re-tightened
  • The gasket showing flattening, hardening or cracking when the joint is opened
  • Repeated pressure loss on the boiler with no other source identified

Before you order

  • Confirm the boiler model is a Milborne 501 or 502 wall hung condensing unit
  • Check the part number on the existing gasket or the manufacturer reference GUARN030 against this listing
  • Verify the connection size as 1 inch before fitting
  • Inspect the mating faces of the pipe and connection for damage before refitting
