18560 - ESAB B-Size Inert Gas Female to 1/4 NPT Male Adapter

Precision Gas System Adaptation

The ESAB 18560 Adapter is a specialized component designed to facilitate the integration of standard welding gas equipment with industrial piping and manifold systems. Engineered with precision, this adapter converts a standard B-Size Inert Gas Female connection (5/8"-18 Right Hand thread) to a 1/4" National Pipe Thread (NPT) Male connection. This specific configuration is essential for professionals who need to interface standard welding hoses or regulators with equipment that utilizes rigid piping or NPT-ported solenoid valves.

Industrial-Grade Materials

Constructed from high-quality brass, this adapter offers superior resistance to corrosion and mechanical wear. Brass is the material of choice for welding gas fittings due to its non-sparking properties and excellent durability under varying pressure conditions. The machined threads are cut to strict tolerances, ensuring a tight, secure fit that minimizes the risk of leaks—a critical factor when handling pressurized shielding gases like Argon, Helium, or Nitrogen. The robust construction ensures that the fitting maintains its integrity even after repeated assembly and disassembly cycles.

Technical Specifications and Compatibility

This adapter is specifically rated for Inert Gas service. The "B-Size" designation refers to the standard CGA 032 connection typically found on inert gas regulators, flowmeters, and hose couplers. By adapting this to a 1/4" NPT Male thread, users can screw this fitting directly into manifolds, machine inlets, or distribution blocks, providing a standardized connection point for a gas hose. It is important to note that the B-Size side features Right-Hand threads, distinguishing it from fuel gas fittings, to prevent accidental cross-connection of incompatible gases.

Applications in Welding and Fabrication

The ESAB 18560 is widely used in the setup of custom welding cells, automated welding systems, and central gas distribution networks. It allows for the seamless transition from hard-piped gas lines to flexible hoses, providing the necessary interface for TIG and MIG welding machines. Whether you are building a custom purge manifold for pipe welding or replacing a damaged inlet fitting on a wire feeder, this adapter provides the reliability and specification compliance required for industrial environments.
