OVERVIEW

Technical Overview: ESAB Acetylene Y-Adapter

The ESAB Acetylene Y-Adapter (SKU: ESB3799) is a precision-engineered brass fitting designed for the distribution of fuel gases in oxy-fuel welding and cutting operations. This component functions as a splitter, converting a single B-Size outlet into two separate B-Size supply lines. It is manufactured to strict industry standards, ensuring compatibility with CGA-022/023 style fittings commonly found on industrial regulators and hoses.

Constructed from high-quality brass, this adapter offers superior resistance to deformation and corrosion, essential for maintaining seal integrity in pressurized gas systems. The unit features a single B-Size (5/8"-18 UNF) Female inlet nut, designed to attach directly to a regulator outlet or a male hose extension. The body splits into two B-Size Male outlets, allowing for the connection of two separate hoses. Crucially, all threads on this device are Left-Hand (LH), indicated by the standard notch on the nut, to prevent accidental cross-connection with oxygen lines, thereby adhering to safety protocols for fuel gas equipment.

This Y-connector is ideal for manifold systems or temporary setups where multiple operators need to draw from a single fuel source. It does not contain internal check valves or flash arrestors; therefore, it is highly recommended that downstream equipment be fitted with appropriate safety devices to prevent reverse flow or flashbacks. The machined seating surfaces ensure a gas-tight seal when tightened to the appropriate torque specifications.

FAQ

This adapter uses standard B-Size fittings, which are 5/8"-18 UNF threads.

These are Left-Hand (LH) threads, which is the industry standard for Acetylene and other fuel gases to prevent cross-connection with oxygen.

No. Oxygen fittings use Right-Hand threads. This adapter is specifically designed for fuel gases with Left-Hand threads.

No, this is a simple Y-splitter block. It does not have shut-off valves for the individual outlets.

It is machined from solid brass for durability and safety in gas service.

Physically yes, but you must ensure your acetylene cylinder has enough capacity. You should not withdraw more than 1/7th of the cylinder's volume per hour. Running two torches might exceed this limit on smaller tanks.

Generally, no. B-Size gas fittings seal on the machined seat (metal-to-metal), not the threads. Ensure the seats are clean and tighten firmly.

Yes, as long as your propane hoses use standard B-Size Left-Hand fittings, this adapter is compatible with propane and other fuel gases.
