What it is

The Glow-worm bypass clip is a 13.5 mm retaining clip used to secure the bypass pipework within compatible Glow-worm boilers and stores. It is supplied in a pack of 15 and is listed under manufacturer part number S5490900, replacing code 2000801961. The clip holds the bypass connection in position so the bypass circuit stays correctly assembled in service.

Signs this part needs replacing

  • The clip is cracked, snapped or has lost its retaining tension
  • The bypass pipe is loose or can be moved by hand
  • A clip is missing from the bypass assembly after servicing
  • Rattle or vibration from the bypass area during operation
  • The bypass connection shows signs of weeping where the joint is no longer held square

Before you order

  • Check your appliance model against the fit list above
  • Confirm the bypass pipe diameter matches the 13.5 mm clip size
  • Check how many clips are needed, as the part is supplied in a pack of 15
  • Inspect the bypass assembly for any other damaged or missing components
