16174 - Miller CGA 023 B-Size Left-Hand Fuel Gas Nut

Industrial Grade Fuel Gas Connection Hardware

The Miller 16174 Nut is a critical component for maintaining the integrity and safety of industrial gas distribution systems. Manufactured to the Compressed Gas Association (CGA) 023 standard, this nut is designed specifically for B-Size hose connections utilized in fuel gas applications. In the realm of industrial maintenance, repair, and operations (MRO), ensuring that gas fittings meet precise specifications is paramount to preventing leaks and ensuring regulatory compliance. This particular component features a 5/8"-18 Unified Fine (UNF) thread with a Left-Hand (LH) orientation, a universal safety standard for fuel gases such as acetylene, propane, and propylene to distinguish them from oxygen and inert gas lines.

Constructed from high-quality brass, the Miller 16174 offers superior machinability and corrosion resistance. Brass is the material of choice for gas fittings due to its non-sparking properties and its ability to deform slightly under compression, creating a robust metal-to-metal seal when paired with the appropriate nipple. This nut is essential for assembling or repairing gas hoses, connecting torches to regulators, or configuring manifold systems. The hexagonal profile is sized for standard wrenches, facilitating proper torque application without rounding the edges. For procurement specialists and facility managers, stocking genuine OEM parts like the Miller 16174 ensures that equipment downtime is minimized and that all connections maintain the manufacturer's intended safety margins.

Whether used in heavy fabrication, HVAC installation, or general plant maintenance, the reliability of gas connections dictates the safety of the work environment. This nut is compatible with a wide range of Miller equipment and standard oxy-fuel apparatuses. It serves as the retaining element that secures the hose nipple against the regulator or torch body, bearing the mechanical load of the connection while allowing the sealing surfaces to engage effectively. By adhering to the CGA 023 standard, this part eliminates guesswork regarding compatibility, providing a dependable solution for fuel gas line maintenance.
