0960-0023 - Victor 1/8" NPT x "A" Size Fuel Hose Adapter

Technical Overview of the Victor 0960-0023 Hose Connection

The Victor 0960-0023 is a specialized hose connection fitting designed to facilitate the interface between rigid piping or regulator bodies and flexible welding hoses. Manufactured from high-grade brass, this component is engineered to withstand the rigors of industrial environments while maintaining dimensional stability and thread integrity. The fitting features a dual-thread configuration: one end is machined with a 1/8-inch National Pipe Thread (NPT) Male taper, while the opposing end utilizes an "A" Size (3/8"-24) Unified Fine (UNF) thread profile.

Crucially, the "A" size end is cut with Left-Hand (LH) threads. In the welding and compressed gas industry, left-hand threads are the universal safety standard for fuel gases—such as Acetylene, Propane, Propylene, and Natural Gas—to prevent accidental cross-connection with oxygen or inert gas lines (which utilize right-hand threads). The "A" size designation refers to the specific 3/8"-24 thread pitch and diameter, which is smaller than the standard "B" size (9/16"-18) typically found on heavy-duty equipment. This makes the 0960-0023 particularly suitable for light-duty torches, specific regulator outlets, or specialized manifold systems requiring a compact connection interface.

The 1/8" NPT end relies on the interference fit of the tapered threads to create a seal, often requiring a suitable sealant such as PTFE tape or pipe dope rated for gas service. Conversely, the "A" size end is designed to mate with a corresponding female hose nut and nipple, where the seal is achieved mechanically through the mating of the nipple seat, not the threads themselves. This distinction is vital for proper installation and leak prevention. The brass material provides excellent resistance to sparking and corrosion, essential properties for components handling flammable gases.

Professionals specifying this part should verify that the mating equipment utilizes the smaller "A" style connection rather than the more common "B" style. Attempting to adapt mismatched sizes without the correct fitting can lead to gas leaks and safety hazards. The Victor 0960-0023 adheres to industry tolerances, ensuring seamless compatibility with other CGA-compliant gas equipment.
