Worcester Bosch Pressure Gauge 87161423980

The Worcester Bosch 87161423980 is a pressure gauge used across a range of the manufacturer's domestic heating appliances. It provides a visual indication of the water pressure inside the appliance, so the reading can be checked at a glance during servicing or fault finding. A pressure reading that falls repeatedly usually points to a leak somewhere on the central heating system rather than a fault with the gauge itself.

• The needle sits at zero or does not move when the system is filled or topped up
• The pressure reading drops repeatedly and the appliance needs frequent topping up
• The dial face is clouded, cracked or the needle sticks at a fixed point
• Corrosion, staining or moisture is visible around the gauge body or its connection
• The gauge reading does not agree with the pressure shown at the filling loop or an external test gauge

• Check the appliance GC number and serial plate to confirm the gauge matches your model before ordering
• Cross-reference the alternative part numbers 1018155, N0737 and WB87161423980 against the component being removed
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
