0558102823 - ESAB G 1/8 to 5/8-18 Gas Adapter Fitting

Precision Gas Connection for Professional Equipment

The ESAB Gas Outlet Adaptor (0558102823) is an essential component for maintaining the integrity and compatibility of your welding or plasma cutting gas delivery system. Designed specifically to bridge the gap between different thread standards, this adaptor converts a G 1/8" (British Standard Pipe) port to a standard 5/8"-18 UNF connection. This is particularly critical for integrating ESAB power sources, which often utilize metric or BSP specifications, with standard North American gas hoses and regulators.

Manufactured from high-grade brass, this fitting offers superior resistance to corrosion and mechanical wear. In industrial environments where equipment is subjected to vibration, thermal fluctuation, and frequent handling, the durability of your fittings is paramount to safety and performance. The precision machining of the threads ensures a tight, leak-proof seal, preventing the loss of expensive shielding gas and eliminating the risk of atmospheric contamination in your weld pool. A secure gas connection is the first line of defense against porosity and weld defects.

This OEM part is engineered to meet ESAB's rigorous quality standards. Unlike generic fittings that may have loose tolerances or inferior metallurgy, the 0558102823 adaptor provides the confidence that comes with using genuine manufacturer components. Whether you are setting up a new Caddy Tig, a Rebel series machine, or a plasma cutter that utilizes G-style ports, this adaptor ensures a seamless workflow. It allows for the use of standard "B-size" inert gas hoses, making it easier to source replacements and accessories locally without needing specialized custom hoses.

Installation is straightforward, featuring machined flats that allow for secure tightening with a standard wrench. By standardizing your equipment connections with this adaptor, you simplify maintenance and reduce the complexity of your shop's inventory. Trust in the reliability of ESAB engineering to keep your gas shielding systems operating at peak efficiency.
