Worcester Bosch Expansion Vessel 10L – Refurbished | Part No. 87161165190 87154072600

Pressure fluctuations in a sealed central heating system are often traced back to a failing expansion vessel. As thermal expansion is no longer absorbed properly, pressure spikes trigger the relief valve repeatedly — causing stress on seals and system components with every cycle. The Worcester Bosch Expansion Vessel 10L (Part No. 87161165190), the official replacement for the superseded 87154072600, restores that pressure balance and protects your boiler from accumulating damage.

This is a professionally refurbished genuine Worcester Bosch component. Each unit is stripped, cleaned, and pressure-tested to OEM specifications — giving you manufacturer-grade performance at a fraction of the new-part cost. The 10-litre capacity provides a direct like-for-like replacement with no modifications needed.
