The Worcester Bosch 87161423000 Pressure Gauge is a genuine replacement instrument designed to accurately display your boiler’s system water pressure. With a 4 bar scale and dark grey bezel, it provides a clear visual reference so you can quickly confirm that your central heating system is operating within the correct pressure range. Maintaining correct water pressure helps protect internal components, supports efficient heat transfer and reduces the risk of boiler lockouts or safety shutdowns due to low or high pressure.

This pressure gauge is compatible with Worcester Bosch CDi and SBi series boilers that specify part number 87161423000. It is suitable for use on models where this gauge is fitted as the standard indicator, and to ensure proper compatibility always check the part number on your existing gauge or consult the boiler’s documentation before fitting.

Designed for straightforward replacement, the 87161423000 pressure gauge installs directly into the existing port on the boiler’s front panel or pressure assembly, utilising original mounting points without modification. Choosing this genuine Worcester Bosch pressure gauge helps restore clear, reliable pressure readings so your boiler can be monitored and maintained effectively.
