Worcester Seal Exhaust 59Dia 2X 8737711102

was 87110043210

Maintain the safety and integrity of your flue system with the Genuine Worcester Bosch 59mm Exhaust Seal (8737711102).

This EPDM rubber lip seal sits inside the socket of Worcester Greenstar standard concentric flues (60/100mm system). It seals the inner 60mm exhaust pipe, preventing dangerous combustion fumes (CO) and acidic condensate from leaking into the air intake or the property. These seals can perish over time due to heat or become dislodged if a flue is adjusted.

Why you need this part:

Safety Critical: A damaged flue seal is an immediate "At Risk" or "ID" safety failure.

Leak Prevention: Ensures condensate runs back to the boiler rather than dripping out of flue joints and damaging ceilings or casings.

Genuine Spare: Designed with the specific 59mm internal diameter and double-lip profile required for Worcester Greenstar flue extensions and elbows.
