2118111 - ESAB B-Size Oxygen Male to 3/8 Tube Adapter (.10 ID)

Precision Brass Adapter for Oxygen Systems

The ESAB 2118111 Adapter is a specialized gas fitting designed to facilitate secure connections within oxy-fuel welding and cutting setups. Engineered with precision, this adapter converts a standard B-Size Oxygen Male fitting to a 3/8-inch Tube connection. This component is essential for professionals who need to fabricate custom hose lengths, repair damaged lines, or interface with specific manifold equipment that utilizes raw tubing inputs.

Constructed from high-quality brass, this adapter offers superior resistance to corrosion and mechanical wear, ensuring a long service life even in demanding industrial environments. The brass material is specifically chosen for its compatibility with oxygen service, minimizing the risk of sparking and ensuring safe operation. The 0.10-inch Inner Diameter (ID) is a critical specification, designed to maintain appropriate flow characteristics or match the wall thickness requirements of specific tubing types used in precision gas delivery.

Safety in welding operations relies heavily on the integrity of gas connections. The ESAB 2118111 features standard 5/8"-18 Right-Hand threads, which is the industry standard for oxygen fittings (CGA 022). This threading convention prevents accidental connection to fuel gas lines (which use left-hand threads), thereby reducing the risk of dangerous cross-connections. Whether you are setting up a new shop manifold, repairing a regulator outlet, or customizing a torch setup, this OEM ESAB part ensures a leak-free and reliable seal.

This adapter is particularly useful for maintenance, repair, and operations (MRO) specialists dealing with legacy equipment or custom gas distribution panels. Its robust design withstands the pressures typical of oxygen service while providing a straightforward solution for adapting threaded ports to slip-on or clamped tubing connections.
