79Z40 - ESAB A-Size Oxygen Male to 3/16 Hose Barb Adapter

Reliable Gas Connections with ESAB 79Z40

The ESAB 79Z40 Adapter is an essential component for professionals and hobbyists utilizing light-duty oxy-fuel equipment. Designed to facilitate a secure connection between gas sources and delivery systems, this adapter specifically converts an A-Size Oxygen female port to a 3/16-inch hose barb. In the world of welding and industrial gas, the integrity of your connections is paramount, not only for the efficiency of your flame but for the safety of your workspace. This fitting is precision-machined from high-quality brass, ensuring it stands up to the rigors of daily use while resisting corrosion and wear.

The "A-Size" standard (3/8"-24 threads) is typically found on smaller, light-duty torches and regulators, often used for jewelry making, HVAC repair, or precise metal fabrication. Unlike the larger "B-Size" fittings, these require specific adapters to interface with standard hoses. The ESAB 79Z40 features Right-Hand (RH) threads, complying with Compressed Gas Association (CGA) standards for oxygen service, effectively preventing accidental cross-connection with fuel gas lines (which use Left-Hand threads). This safety feature is critical in preventing dangerous gas mixes within the equipment.

Installation is straightforward. The threaded male end screws securely into your regulator or torch handle, while the barbed end inserts into a 3/16-inch inner diameter (I.D.) oxygen hose. For a permanent and leak-free seal, it is recommended to use a crimp ferrule or a high-quality hose clamp over the barb. Whether you are repairing a damaged hose line or customizing a new torch setup, the ESAB 79Z40 provides the reliability you expect from a world leader in welding technology.
