Venturi 423.173A (Bosch part no. 7746900148) is an OEM venturi gas‑mixing insert intended for Bosch gas‑fired burner assemblies. It regulates the air–gas mixture at the burner throat to support consistent ignition and modulation, and is supplied as a service replacement to simplify in‑field boiler repairs and routine maintenance — a practical spare for technicians handling Bosch burner servicing.
