What it is

The Glow-worm 801672 is an O-ring used on Glow-worm Flexicom and GW series gas boilers. It forms a sealing joint within the appliance, preventing water or gas from escaping at the point where components meet. It is a small service part, typically renewed whenever the joint it seals is disturbed.

Signs this part needs replacing

  • Visible water staining, weeping or dripping at the joint the O-ring seals
  • The O-ring is cracked, split or perished
  • The O-ring has hardened or flattened and no longer sits proud of its groove
  • Loss of system pressure with no other obvious cause
  • The O-ring is disturbed during servicing and cannot be reused

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the part number 801672 matches the item you are replacing
  • Check how many O-rings the joint requires before ordering
  • Inspect the mating surfaces for corrosion or damage that could affect the seal
