18K02 - ESAB 18K02 Oxygen Connection for W-201 Torch

Technical Overview of the ESAB 18K02 Oxygen Connection

The ESAB 18K02 is a precision-engineered replacement component designed specifically for the Purox W-201 series welding torches. As a critical element of the torch's gas delivery system, this oxygen connection ensures the secure and leak-proof transfer of oxygen from the supply hose to the torch mixing chamber. Manufactured to original equipment manufacturer (OEM) specifications, the 18K02 guarantees compatibility with the W-201 handle, maintaining the torch's balance, weight distribution, and ergonomic profile.

Constructed from high-grade brass, the connection offers superior resistance to oxidation and mechanical wear, essential for the harsh environments typical of industrial welding and brazing. The machining tolerances are held to strict standards to ensure a perfect mate with standard oxygen hose fittings (typically CGA-022 or B-size right-hand threads, depending on the specific assembly context) and the internal seating of the torch body. Proper maintenance of these connections is vital for preventing gas leaks, which can lead to dangerous flashbacks or inconsistent flame characteristics.

In the context of oxy-fuel equipment maintenance, replacing worn or damaged connections is a standard safety protocol. Over time, threads can become stripped, or seating surfaces can become marred, compromising the seal. The ESAB 18K02 provides a direct replacement solution that eliminates the need for makeshift repairs or adapters, ensuring that the W-201 torch continues to operate within its design parameters for flow rate and pressure handling. This part is integral to the longevity of the W-201, a torch renowned for its durability in medium-duty welding and heating applications.

Installation of the 18K02 requires standard torch repair tools. Technicians should ensure that all mating surfaces are clean and free of oil or grease—a critical safety rule for all oxygen service components to prevent combustion hazards. By utilizing genuine ESAB parts like the 18K02, facilities ensure compliance with safety standards and maintain the operational integrity of their welding apparatus.
