What it is

The Alpha Y hose union (part number 1.024387) is a T piece used on the manifold tray tube of Alpha gas boilers. It forms part of the condensate and manifold drainage path, joining hose runs into a single outlet. It is listed by the manufacturer as a T piece - manifold tray tube.

Signs this part needs replacing

  • Water or condensate weeping from the union or its connections
  • Visible cracking, splitting or perishing of the T piece
  • Scale or corrosion build-up restricting flow through the tube
  • The hose union working loose and no longer sealing on the manifold tray tube
  • Damp staining or pooling beneath the boiler around the manifold tray area

Before you order

  • Confirm your boiler model and, where shown, the GC number against the fitment list
  • Check the existing part number 1.024387 on the component or in the manufacturer's parts list
  • Inspect the associated hoses and manifold tray tube for damage that may also need attention
  • Verify the number and orientation of connections on the existing T piece before fitting
