35Z64 - ESAB 35Z64 Mixing Chamber Plug for AC-4 Torch

Genuine ESAB 35Z64 Mixing Chamber Plug for AC-4 Torches

The ESAB 35Z64 Mixing Chamber Plug is a critical replacement component designed specifically for the maintenance and repair of AC-4 oxy-fuel torches. In the high-stakes environment of industrial cutting and welding, the integrity of your equipment is paramount. The mixing chamber is the heart of the torch, where oxygen and fuel gas combine in precise ratios to create the preheat flame and cutting stream. This plug serves as the essential seal for that chamber, ensuring that gases are contained and directed properly towards the tip, rather than leaking externally or internally where they could cause performance issues or safety hazards.

Manufactured to ESAB's exacting OEM specifications, this plug is crafted from high-quality brass, offering excellent durability and resistance to the thermal cycles and mechanical stresses typical of welding environments. Using non-OEM parts in oxy-fuel equipment can lead to poor thread engagement or imperfect sealing surfaces, which significantly increases the risk of gas leaks. A leaking mixing chamber not only reduces the efficiency of your flame—leading to wasted gas and poor cut quality—but also poses a serious safety risk, including the potential for flashbacks or torch fires. By choosing the genuine 35Z64 plug, you ensure that your AC-4 torch continues to operate as designed, maintaining the safety and reliability expected from ESAB equipment.

This component is ideal for equipment repair specialists, maintenance departments, and professional welders who perform their own torch overhauls. It is a direct-fit part, meaning no modification is required for installation. Regular inspection of torch components, including plugs and seals, is a recommended practice in any preventative maintenance program. If your existing plug shows signs of thread wear, rounding, or physical damage, immediate replacement with this authentic ESAB part is the best course of action to restore your tool's functionality.

Technical Reliability

The 35Z64 is engineered to withstand the pressures associated with oxy-fuel processes. Its precision threading ensures a tight, secure fit that resists loosening under vibration. Whether you are refurbishing an older Purox-style AC-4 torch or maintaining a newer ESAB unit, this plug provides the assurance of compatibility and performance that generic aftermarket parts cannot guarantee.
