OVERVIEW

Double Your Output with the Oxygen Y-Connector

Need to run two torches but only have one oxygen tank? The Oxygen Y-Connector Adapter (B-Size) is the simple, durable solution you need to expand your welding or cutting setup instantly. Whether you are training a new welder, running a dual-station fabrication job, or simply need a backup line for a different tool, this heavy-duty brass splitter lets you connect two hoses to a single regulator effortlessly. No need to buy a second cylinder or swap out regulators constantly—just screw this adapter on, and you are ready to work.

Built for the shop environment, this adapter is tough. It is machined from solid brass, meaning it can take the knocks and bumps of daily shop life without cracking or stripping threads. The connections are standard "B-Size" (9/16"-18), which is the industry standard for almost all oxy-fuel equipment in the United States. The threads are Right-Hand (RH), specifically for Oxygen lines, ensuring you never accidentally connect it to a fuel gas line (which uses Left-Hand threads). The swivel nut on the female side makes installation a breeze, allowing you to tighten the adapter onto your regulator in any orientation without twisting your hoses.

Using a Y-connector is a smart way to get more value out of your equipment. It is perfect for shops with limited space for cylinders or for mobile rigs where carrying extra tanks isn't an option. Just remember to check your regulator's flow capacity to ensure it can handle two torches at once. With this simple upgrade, you can turn one workstation into two, boosting productivity and flexibility in your metalworking projects.

Key Benefits

  • Universal Fit: Works with all standard B-Size oxygen hoses and regulators.
  • Durable: Solid brass construction resists rust and wear.
  • Easy Install: Swivel nut design allows for quick, tool-tight connections.

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.
