The Worcester 87110043650 Door Seal is a genuine replacement sealing gasket designed to create an airtight, combustion-tight seal around the boiler’s access or service door. This seal prevents air leakage into or combustion gases from escaping out of the boiler casing, helping maintain correct airflow dynamics, stable combustion efficiency and safe operation. A worn, cracked or compressed door seal can lead to reduced performance, noise, fault codes or unsafe conditions, so fitting the correct OEM seal is essential for reliable boiler function and safety.

This door seal is compatible with Worcester and Worcester Bosch boilers that reference part number 87110043650 in their technical documentation. To ensure correct fitment and optimal performance, always verify the part number on your existing seal or consult your boiler’s service information before installation, as seal shapes and dimensions vary between models and casing designs.

Supplied ready for direct replacement, the 87110043650 Door Seal installs around the boiler’s access panel edge when fitted by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore proper sealing integrity, supports safe and efficient combustion airflow and contributes to dependable heating performance in compatible boilers.
