To ensure proper fitment and reliable performance, always verify the part number on your existing charging link or consult your boiler’s service information before installation, as charging link designs and hose lengths can vary between models and configurations.

Supplied ready for direct installation, the 87161051030 Charging Link Assembly integrates with your boiler’s existing cold-water supply and central heating pipework when fitted by a qualified Gas Safe engineer. Choosing this genuine Worcester Bosch component helps maintain correct system filling procedures, supports stable pressure control and contributes to dependable central heating performance in compatible CDi boilers.
