Product Overview

The Worcester Bosch Flue Seal (Part Number: 87161116730) is a sealing component designed for selected Worcester Bosch boiler flue systems.

The seal measures 100mm x 8mm and is used within suitable flue duct connections to help maintain a secure seal between adjoining components.

The seal forms part of the flue system's sealing arrangement, helping prevent the escape of combustion gases through the relevant connection during normal appliance operation.

Technical Insight & Common Failure Symptoms

The flue seal provides a sealing interface between suitable flue components, helping maintain the integrity of the connected flue system.

Over time, sealing components may deteriorate due to heat exposure, compression, ageing or physical damage. A damaged or incorrectly fitted seal may compromise the integrity of the flue connection.

Possible signs that a flue seal may require inspection or replacement include:

• Visible cracking or deterioration of the seal.

• Flattening, deformation or loss of flexibility.

• Tears, splits or other physical damage.

• Seal failing to sit correctly within the flue connection.

• Damage identified during flue inspection or servicing.

• Signs of deterioration affecting the integrity of the flue joint.

These signs do not necessarily confirm that the seal is responsible for a flue-related fault, as similar problems may result from incorrectly fitted duct sections, damaged connections or other flue components. Professional inspection should be carried out before replacement.

Compatibility

This part (MPN: 87161116730) is associated with selected Worcester Bosch 60/100mm concentric flue systems, including compatible flue extensions, bends and terminal arrangements.

Please verify the exact flue configuration, part number, seal dimensions and installation requirements against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler flue seals are safety-critical components within the appliance's combustion and flue system. Inspection, removal and installation must only be carried out by a Gas Safe registered engineer who is suitably qualified for the appliance and work being undertaken.

Always isolate the appliance before carrying out any work and follow the manufacturer's installation and servicing instructions. Ensure the seal is correctly positioned and that all flue connections are securely assembled. Appropriate flue integrity, combustion and operational safety checks must be completed before the boiler is returned to service.
