18K05 - ESAB Oxygen Adapter - B-Size Male to 3/8 Inch Tube

Precision Brass Adapter for Oxygen Service

The ESAB 18K05 is a specialized gas adapter designed to facilitate secure connections in oxy-fuel welding and cutting setups. Engineered with precision-machined brass, this fitting ensures durability and resistance to corrosion, which is critical for maintaining the integrity of gas delivery systems over time. The adapter features a standard B-Size Oxygen Male thread (9/16"-18 Right Hand) on one end, allowing it to interface seamlessly with standard regulators, torches, and hose couplers commonly found in the industry.

The opposing end is configured for a 3/8" Tube connection, making this component essential for custom manifold builds, equipment retrofits, or specific hose repair scenarios where transitioning to hard tubing or specific hose barbs is required. Proper gas flow and leak prevention are paramount in oxygen service to prevent safety hazards; this ESAB fitting is manufactured to tight tolerances to ensure a metal-to-metal or seated seal that meets industrial safety standards.

Professionals rely on ESAB's range of Western-style brass fittings for their consistency and quality. Whether you are configuring a workshop manifold, repairing a damaged line, or adapting a regulator for a specific machine application, the 18K05 provides the reliability needed for high-performance welding environments. Always ensure threads are clean and compatible before installation to maintain a safe working pressure.
