OXYYVALVE - Oxygen Y-Connector with Shut-Off Valves

Technical Overview: Oxygen Y-Valve Assembly

The DIXOXYYVALVE is a precision-engineered Y-Valve assembly designed specifically for oxygen gas distribution in industrial welding and cutting environments. Constructed from high-quality solid brass, this fitting ensures maximum durability and resistance to oxidation and corrosion common in oxy-fuel applications. The unit functions as a manifold, converting a single supply source into two controllable outlets.

Technically, the assembly features a standard B-Size (CGA 022) configuration. The inlet is a 9/16"-18 Right Hand (RH) female swivel nut, designed to attach directly to the outlet of a standard oxygen regulator or piping drop. The two outlets are 9/16"-18 Right Hand (RH) male connections, compatible with standard oxygen welding hoses. Crucially, this assembly is rated for oxygen service, meaning all internal components and lubricants are oxygen-compatible to prevent combustion hazards.

The defining feature of this model is the integration of dual independent shut-off valves. These needle-style valves allow for positive shut-off of flow to either outlet individually. This capability is essential for maintenance, changing torch setups, or isolating a line without depressurizing the entire system. The valve stems are machined for smooth operation and reliable sealing under standard working pressures (typically up to 200 PSIG for cutting oxygen). This component is an essential fitting for expanding the utility of single-cylinder stations in fabrication shops.
