What it is
The Worcester Bosch Connection Joint Seal is a 62mm sealing component designed for use in the flue system of Worcester Bosch boilers. It is fitted at connection joints within the flue assembly to prevent the escape of water or harmful gases as they travel through the boiler. Seals of this type are critical for maintaining the safety and efficiency of the appliance, as they ensure that combustion by-products are safely directed outside and that condensate does not leak into the surrounding area.
Signs this part needs replacing
- Visible cracks, hardening or deterioration of the seal material
- Flue gas odours or signs of leakage around the flue joint
- Water stains or drips near the flue connection
- Boiler pressure loss or performance issues linked to flue integrity
- The seal no longer sits correctly or has become displaced
- Discolouration or brittleness indicating heat damage
