What it is

The Glow-worm S1064400 is a flexible pipe that links the expansion vessel to the hydraulic circuit on a range of Glow-worm gas boilers. Manufacturer data lists it as a Schrader extension. It carries system water between the vessel and the boiler's internal pipework.

Signs this part needs replacing

  • Water weeping or dripping from the hose body or its crimped end fittings
  • Visible cracking, hardening or blistering of the flexible section
  • Water staining or corrosion around the expansion vessel connection
  • Boiler losing system pressure with no other visible leak
  • Pressure gauge fluctuating, or the expansion vessel failing to hold charge

Before you order

  • Confirm your boiler model against the fit list above
  • Check that the connections at both ends of the existing hose match
  • Have the part number S1064400 to hand when ordering
