33A34 - ESAB 33A34 Oxweld Style Nozzle Retaining Nut

Precision Replacement for Industrial Cutting Torches

The ESAB 33A34 Nozzle Nut is a critical replacement component designed for the maintenance and repair of Oxweld oxy-fuel cutting torches. Specifically engineered to fit the 1400 Series and compatible C-Series torch bodies, this nut serves the vital function of securing the cutting nozzle (tip) to the torch head. In high-pressure oxy-fuel cutting applications, the integrity of this connection is paramount; a compromised nut can lead to gas leaks, flashbacks, or poor cut quality due to tip misalignment.

Manufactured from high-grade industrial brass, the 33A34 offers excellent thermal conductivity and resistance to deformation at elevated temperatures. The material choice minimizes the risk of the nut seizing to the torch head, a common issue in heavy-duty cutting environments where equipment is subjected to extreme heat cycles. The internal threads are precision-cut to match Oxweld specifications exactly, ensuring a smooth engagement that seats the nozzle firmly against the torch head's seating surface without damaging the threads.

For maintenance professionals and tool crib managers, stocking genuine OEM parts like the ESAB 33A34 ensures equipment longevity and operator safety. Unlike generic aftermarket alternatives, this nozzle nut guarantees the correct compression force is applied to the nozzle seating area, maintaining the separation of preheat gases and cutting oxygen. It is an essential spare part for fabrication shops, shipyards, and heavy industrial facilities utilizing Oxweld cutting systems.

Technical Reliability

The external surface of the nut features a knurled or hex design (depending on specific vintage production) to facilitate proper tightening. While hand-tightening is often sufficient for initial seating, the design allows for the use of a wrench to ensure the manufacturer-specified torque is achieved, preventing loosening during operation. Regular inspection of nozzle nuts for thread wear or impact damage is recommended as part of a standard preventative maintenance schedule.
