What it is

The Glow-worm Compression Union is a pipework fitting supplied for the Glow-worm Ultrapower Sxi range. It joins two pipe ends by compressing an olive onto the pipe as the nut is tightened, forming a mechanical seal at the joint. It is a service part intended for use on the appliances listed below.

Signs this part needs replacing

  • Weeping or damp staining around the compression joint
  • Visible corrosion or scale on the nut or union body
  • A joint that will not seal when re-tightened
  • Water tracking along the pipe from the union
  • Seepage appearing after the joint has been disturbed during servicing

Before you order

  • Confirm the appliance model against the fit list above
  • Check the pipe size and thread at the existing joint before ordering
  • Inspect the mating pipework for damage that could prevent a clean seal
