What it is
The Worcester Bosch 87161405000 is an automatic air vent supplied as a stainless steel kit with a 3/8 inch connection. It is mounted at a high point in the appliance water circuit, where it releases trapped air automatically so that water can circulate freely through the heat exchanger. The part is used across a broad range of Worcester Bosch gas boilers and water heaters.
Signs this part needs replacing
- Air keeps collecting at the top of the appliance and the system needs bleeding repeatedly
- Kettling, gurgling or rushing noises from the heat exchanger or pipework
- Water weeping or dripping from the vent body or its connection
- The vent cap no longer seals, or the internal float sticks and the vent fails to close
- Uneven heating, with the upper part of the appliance or radiators running hot while lower sections stay cool
Before you order
- Check the GC number on the appliance data badge against the compatibility list before ordering.
- Older stock or documentation may carry the previous number ZMMIS055.
- Confirm whether a sealing washer is needed for the 3/8 inch connection.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
