679064 - ESAB Oxygen Bulkhead Adapter - B-Size Female to 1/4 NPT Male

ESAB 679064 Oxygen Bulkhead Adapter Overview

The ESAB 679064 is a specialized brass adapter designed for industrial gas management systems. It functions as a bulkhead fitting, allowing users to pass an oxygen line securely through a panel, cabinet wall, or machine enclosure. The primary configuration features a B-Size Oxygen Female connection on one end and a 1/4-inch NPT Male thread on the other. This specific combination is essential for integrating standard welding hoses with hard-piped manifolds or regulators that utilize National Pipe Taper (NPT) ports.

Constructed from high-quality brass, this adapter offers excellent resistance to corrosion and deformation under pressure. The B-Size connection utilizes standard 9/16"-18 threads with a Right-Hand (RH) orientation, adhering to CGA safety standards for oxygen service to prevent cross-connection with fuel gases. The 1/4" NPT Male end provides a universal fit for a wide range of industrial pipe fittings, valves, and regulators.

In professional fabrication environments, cable and hose management is critical. Using a bulkhead adapter like the ESAB 679064 allows for cleaner setups where gas lines are routed internally within machines or carts, emerging only where necessary. This protects the gas lines from external damage and reduces clutter in the workspace. Whether you are building a custom welding cart, repairing a cutting machine, or setting up a central gas distribution panel, this adapter provides the reliable, leak-free connection required for safe oxygen handling.
