3798 - Oxygen Y-Connector Splitter B-Size Female to Dual Male

Industrial Grade Oxygen Y-Connector Adapter

The ESB3798 Oxygen Y-Connector is a critical component for industrial gas distribution systems, designed to maximize the utility of existing oxygen supply infrastructure. Manufactured from high-quality, precision-machined brass, this adapter provides a robust and reliable solution for splitting a single gas source into two independent outlets. It is specifically engineered for Oxygen service, featuring standard B-Size (9/16"-18) Right-Hand (RH) threads that ensure compatibility with the vast majority of North American industrial regulators and hose assemblies.

In professional welding and fabrication environments, efficiency and safety are paramount. This Y-block adapter allows facility managers and operators to run two separate downstream applications—such as two cutting torches or a heating and cutting station—from a single regulator. The unit features one female inlet nut that attaches directly to the regulator outlet or a supply hose, and two male outlet threads that accept standard B-size hose nuts. The internal machining is optimized to minimize flow restriction, ensuring that both downstream lines receive adequate flow for stable flame characteristics, provided the regulator has sufficient capacity.

Safety is engineered into every aspect of this fitting. The brass material is not only resistant to corrosion and mechanical damage but is also compatible with oxygen service, reducing the risk of ignition associated with incompatible materials. The seating surfaces are precision-cut to ensure a gas-tight seal when tightened to specification, preventing hazardous leaks in the work area. This adapter is an essential inventory item for MRO (Maintenance, Repair, and Operations) cribs, allowing for rapid reconfiguration of workstation layouts and gas manifold systems.
