0960-0073 - Victor Fuel Inlet Bushing 9/16-18 LH x 1/4 NPT

Technical Overview of the Victor 0960-0073 Fuel Inlet

The Victor 0960-0073 is a specialized fuel inlet fitting designed for the maintenance and repair of industrial oxy-fuel gas apparatus. Manufactured from high-quality brass, this component is engineered to withstand the rigors of welding and cutting environments while providing a leak-proof connection point for fuel gas delivery systems. The fitting serves as a critical interface between the internal gas passages of a device (such as a regulator body or torch handle) and the external gas supply hose.

Technically, the component features two distinct thread profiles. The first is a 9/16-18 LH (Left-Hand) thread. This is the industry-standard CGA "B" size connection for fuel gases, including Acetylene, Propane, Propylene, and Natural Gas. The left-hand thread direction is a mandatory safety feature in the welding industry, physically preventing the accidental connection of oxygen hoses (which use right-hand threads) to fuel lines, thereby mitigating the risk of catastrophic flashbacks or explosions. The thread pitch and diameter are machined to tight tolerances to ensure smooth engagement with standard hose nuts.

The opposing end of the fitting utilizes a 1/4-18 NPT (National Pipe Taper) thread. This tapered thread profile is designed to create a pressure-tight seal when installed into the mating port of the equipment. As the fitting is torqued, the tapered threads compress, creating a mechanical seal that is often supplemented with an appropriate thread sealant or PTFE tape compatible with fuel gases. The use of NPT threads allows for a secure, semi-permanent installation into the equipment housing.

This component is an OEM (Original Equipment Manufacturer) part from Victor, ensuring exact dimensional compatibility with specific Victor regulators and torch handles that utilize this port configuration. Using genuine repair parts is essential for maintaining the UL listing and safety certification of gas equipment. Mismatched or generic fittings may suffer from poor thread engagement or inferior metallurgy, leading to gas leaks. The brass composition offers natural spark resistance and excellent corrosion resistance against atmospheric moisture and industrial contaminants.
