What it is

The Vokera 8873 is a connection for the domestic expansion vessel, listed by the manufacturer as a flow pipe connecting nipple. It forms the link between the expansion vessel and the boiler's water circuit on the Vokera Hydra, Pinnacle and Eclipse ranges. It is a serviceable part, replaced when the joint or nipple can no longer seal correctly.

Signs this part needs replacing

  • Water weeping or dripping at the expansion vessel connection
  • Corrosion, scale or pitting on the nipple or its threads
  • Falling system pressure with no other obvious cause
  • Damp, staining or residue around the connection point
  • The joint will not seal cleanly when reassembled

Before you order

  • Confirm your boiler model and GC number against the fit list above
  • Establish whether the connection or the expansion vessel itself is at fault
  • Inspect the mating pipework and any seals for damage before fitting
