The ESAB 33A54 is a specialized connection nut designed for precision applications within welding gas and fluid delivery systems. Manufactured to strict OEM tolerances, this component is essential for maintaining the integrity of hose connections on ESAB welding power sources, wire feeders, and torch assemblies. The nut features a specific thread profile of .44-20F (7/16"-20 UNF), a common standard in industrial gas fittings, ensuring compatibility with matching male flare or compression fittings.
Constructed from high-quality brass, the 33A54 offers excellent resistance to corrosion and oxidation, which is critical in environments where shielding gases or cooling fluids are present. The material properties of brass also prevent galling when threaded onto steel or stainless steel fittings, allowing for repeated assembly and disassembly during maintenance cycles without damaging the threads. The internal diameter (ID) is precision-bored to 0.225 inches, providing the necessary clearance for specific hose stems, liners, or capillary tubes used in ESAB equipment.
This component is identified by the internal SKU ESB33A54 and is categorized under general welder accessories and fittings. It serves as a direct replacement for damaged or lost nuts during equipment refurbishment. Proper torque application is recommended to achieve a gas-tight seal without over-compressing associated O-rings or ferrules. Industrial MRO procurement specialists should verify the thread pitch and ID requirements of their specific equipment manuals before ordering to ensure this 33A54 part is the correct specification for their system.
