Worcester Bosch 6 Litre Expansion Vessel – Genuine Refurbished Part | MPN 87161055450

Your boiler works hard every day — and behind every reliable heating system is a network of components quietly doing their job. The Worcester Bosch Expansion Vessel (6 Litre, MPN 87161055450) is one such unsung hero. Housed within your boiler's sealed heating circuit, it continuously absorbs and compensates for pressure changes that occur as water heats and expands — protecting your system from the kind of stress that leads to costly breakdowns over time.

This is a professionally refurbished, genuine Worcester Bosch component, recovered from a fully functioning boiler, rigorously tested, and cleared for reinstallation. It performs exactly as the original — because it is the original, just given a new lease of life.
