The Worcester Bosch 87161044610 Air Pressure Switch (manufactured by Huba) is a genuine replacement safety device that monitors air pressure within the flue and combustion chamber of your boiler. By detecting the correct differential pressure, it confirms that the fan and flue system are operating properly before allowing ignition to proceed. If air pressure is outside safe parameters, the switch triggers a boiler lockout to protect internal components and prevent unsafe combustion conditions.

This air pressure switch is compatible with a range of Worcester Bosch CDi and Junior series boilers that reference part number 87161044610. It fits appliances where the Huba-branded pressure switch is specified as the OEM component. To ensure correct fitment, always verify the part number on your existing switch or check your boiler’s documentation before installation.

Designed for straightforward replacement, the 87161044610 Air Pressure Switch connects directly to the existing tubing and electrical harness, allowing seamless integration without modification. Choosing this genuine Worcester Bosch part helps maintain accurate combustion safety monitoring, reliable fault detection and continued boiler performance in compatible CDi and Junior models.
