Y-piece with a valve acetylene

A Y-piece with a valve for acetylene is a brass fitting designed to connect directly to an acetylene regulator, allowing a single acetylene source to supply two separate hoses or pieces of equipment. Each outlet of the Y-piece is equipped with an independent valve, providing individual on/off control and the ability to adjust the flow rate of acetylene through each line.

Key Features:

• Splits Acetylene Supply: Divides the flow of acetylene gas from one regulator into two separate lines.
• Individual Control Valves: Each outlet has its own valve for independent control of gas flow.
• Left-Hand (LH) Threading: Typically features standard left-hand threading, which is specific to fuel gases like acetylene, to prevent accidental connection to oxygen lines.
• Durable Brass Construction: Made from brass for strength and resistance to corrosion.
• Standard Outlet Fittings: Usually features standard welding hose fittings (e.g., 5/8″ UNF LH) for easy connection to acetylene hoses.

Common Applications:

• Oxy-Acetylene Welding/Cutting: Enables two welders or cutting torches to operate from a single acetylene cylinder and regulator, improving efficiency.
• Heating and Brazing: Allows for simultaneous use of a heating torch and a brazing torch, or feeding two heating torches for larger tasks.
• Other Dual Acetylene Applications: Can be used in any situation requiring two independently controlled streams of acetylene from a single source.

Important Considerations:

• Regulator Capacity: Ensure the acetylene regulator has a sufficient flow rate capacity to adequately supply both outlets when in use.
• Hose Compatibility: Verify that the Y-piece outlet threads match the fittings on your acetylene hoses. Acetylene hoses are typically red and have left-hand threaded fittings.
• Flashback Arrestors: It is crucial to use flashback arrestors on both outlet lines of the Y-piece, near the torch end and preferably also at the regulator end, to prevent dangerous flashbacks from traveling back to the acetylene cylinder.
• Safety: Always handle acetylene and related equipment with extreme caution and adhere to all safety regulations for oxy-fuel gas w
