What it is

The Alpha 1.039171 Telescopic Joint is a flue assembly component manufactured by Alpha for use within the flue system of Alpha gas appliances. The telescopic section slides to the required length during installation, letting the flue run be set accurately to the wall or roof penetration before being secured. It is a serviceable part of the flue assembly, so it is replaced when the joint itself is damaged or no longer seals correctly.

Signs this part needs replacing

  • Visible corrosion, cracking or distortion on the telescopic section
  • Flue joints that no longer seal, with staining or condensate tracking around the joint
  • The flue length has shifted, or the joint will not hold its set position
  • Water ingress around the flue penetration
  • Combustion readings or plume behaviour outside the expected range at the terminal

Before you order

  • Confirm the appliance model and GC number, as flue components differ between Alpha ranges
  • Inspect the existing joint and any seals or gaskets that may need renewing at the same time
