01Y75 - ESAB C-67 Oxygen/Fuel Gas Injector Assembly for CW-23

Technical Overview: ESAB C-67 Injector Assembly (01Y75)

The ESAB 01Y75 is a C-67 style injector assembly designed for specific oxy-fuel cutting attachments, most notably the CW-23 series. In injector-style torches (often referred to as low-pressure torches), the injector is a critical internal component responsible for the aspiration of the fuel gas. By utilizing the Venturi effect, the high-pressure oxygen stream passes through the injector nozzle, creating a low-pressure zone that draws the fuel gas into the mixing chamber. This precise interaction is essential for maintaining the correct stoichiometric ratio for combustion.

Manufactured to strict OEM tolerances, this brass assembly ensures leak-free performance and consistent gas flow. Wear or damage to the injector can lead to dangerous conditions such as backfires or flashbacks, as well as poor flame stability. The 01Y75 replaces worn factory units to restore the original safety and performance parameters of the equipment. It is compatible with Oxygen and Fuel Gas (OX/FG) service, making it a versatile component for workshops utilizing ESAB/Oxweld infrastructure.

Installation of the C-67 injector requires disassembly of the cutting attachment's mixing section. Technicians should verify the condition of all O-rings and seating surfaces during replacement to prevent gas bypass. This part is identified by the internal SKU ESB01Y75 and is supplied as a single unit assembly.
