What it is

The Vaillant 194125 reducing ring is a sealing component used in the pipework and hydraulic assemblies of older Vaillant gas boilers. It is supplied under the manufacturer part number 194125 and sits within the O-rings, washers and gaskets group of boiler spares. Its role is to seat and seal a reducing connection so that the joint remains sound under normal operating pressure and temperature.

Signs this part needs replacing

  • Weeping or damp staining at the joint the ring seals
  • Visible cracking, flattening or hardening of the ring material
  • The ring has been disturbed during a repair and no longer seats correctly
  • Persistent minor water loss traced to a reducing connection

Before you order

  • Check the existing component or appliance documentation against part number 194125
  • Confirm your boiler model and variant against the fitment list above
  • Inspect the removed ring for profile and condition so the correct item is refitted
