OVERVIEW

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.

FAQ

No. This adapter has Right-Hand (RH) threads which are designed for Oxygen or inert gases. Fuel gases like Acetylene and Propane use Left-Hand (LH) threads (notched nuts) to prevent cross-connection accidents. You need a fuel gas specific Y-connector for those gases.

No, this is a standard Y-block adapter without shut-off valves. Both outlets will be live when the gas is turned on. If you need independent control of each line, you should look for a Valved Y-Connector.

B-Size fittings have a 9/16"-18 thread. For Oxygen, this is a Right-Hand thread. This is the standard size for most welding regulators and hoses used in North America.

No. This adapter is designed for the low-pressure side of the system (downstream of the regulator). It should never be connected directly to high-pressure cylinder valves or used in high-pressure pigtails.

It depends on your regulator's flow capacity. If your regulator can supply enough cubic feet per hour (CFH) for both tips combined, the flame will be stable. If the regulator is undersized, you may experience flow starvation when both torches are used simultaneously.

No. Welding fittings like this use a metal-to-metal seat (usually a ball-and-cone design) to seal. Teflon tape can actually cause leaks by preventing the seat from engaging fully or by introducing debris into the system. Tighten securely with a wrench, but do not use tape.

No. You should never use a simple Y-connector to combine cylinders without proper check valves and manifold protocols, as pressure differences can cause backflow and dangerous situations. This is designed for splitting one source to two outlets.

It is manufactured from solid brass, which is the industry standard for oxygen fittings due to its durability, non-sparking properties, and compatibility with oxygen.
