18Z57 - Oxygen Adapter A-Size Female to B-Size Male Brass Fitting

Reliable Oxygen Connection Adapter

The ESAB 18Z57 Oxygen Adapter is an essential component for professionals in the welding and fabrication industry who require versatility in their equipment setup. Designed to bridge the gap between different standard sizes of oxy-fuel connections, this adapter specifically converts an A-Size Female thread (3/8"-24) to a B-Size Male thread (9/16"-18). This functionality is critical when attempting to connect light-duty torches or regulators, which typically utilize A-size fittings, to standard medium or heavy-duty hoses that employ B-size fittings.

Constructed from high-quality brass, this fitting is engineered to withstand the rigors of industrial environments. Brass is the material of choice for oxygen fittings due to its spark resistance and durability. The precision machining ensures that threads engage smoothly and securely, creating a gas-tight seal that prevents dangerous leaks. In oxy-fuel applications, safety is paramount, and using the correct adapter that adheres to Compressed Gas Association (CGA) standards is vital for preventing accidents.

This adapter features Right-Hand (RH) threads, which is the industry standard for oxygen service to prevent cross-connection with fuel gases (which use Left-Hand threads). The clear distinction helps maintain a safe working environment. Whether you are setting up a new workstation, repairing existing equipment, or need a quick solution in the field to mate mismatched components, the ESAB 18Z57 provides a robust and reliable solution. Its compact design adds minimal length to the assembly, ensuring that the ergonomics of your torch or regulator setup remain comfortable and efficient.

Key Benefits:

• Seamlessly adapts A-size equipment to B-size hoses.
• Heavy-duty brass construction resists corrosion and wear.
• Standardized threads ensure compatibility with major brands.
• Enhances the versatility of your welding equipment inventory.
