010606 - Miller Brass Hose Nut 5/8-18 RH

Reliable Gas Connections with Miller OEM Parts

The Miller 010606 Fitting, Hose Brass Nut .625-18 RH is an essential component for maintaining the integrity of your welding gas delivery system. Manufactured by Miller Electric, this high-quality brass nut is designed to secure hose nipples to regulators, flowmeters, and wire feeders. The fitting features a standard 5/8"-18 Right Hand (RH) thread, commonly referred to as a "B-size" connection in the welding industry. This specific thread pitch and direction are the standard for Oxygen (CGA 022) and Inert Gases (CGA 032) such as Argon, Helium, and Nitrogen, making this nut a versatile part for various welding processes including MIG, TIG, and Oxy-Fuel cutting.

Constructed from solid brass, this hose nut offers superior durability and resistance to corrosion, which is critical for components exposed to industrial environments and varying atmospheric conditions. Brass is the material of choice for gas fittings due to its non-sparking properties and ability to create a tight metal-to-metal seal when used with the appropriate nipple. Using genuine Miller OEM parts ensures that the threading is precision-machined to exact tolerances, reducing the risk of cross-threading or gas leaks that can compromise weld quality and shop safety.

Whether you are repairing a damaged gas hose, assembling a new custom length hose, or replacing a worn-out nut on your regulator, the Miller 010606 provides the reliability professional welders demand. A secure gas connection is vital for maintaining consistent shielding gas coverage, preventing porosity in welds, and ensuring the efficient operation of your equipment. This nut is designed to slide over standard hose nipples before the ferrule is crimped or the hose is clamped, providing the mechanical force needed to seat the nipple against the regulator or machine outlet.

Technical Specifications

The .625-18 RH specification indicates a 5/8-inch nominal diameter with 18 threads per inch, turning clockwise to tighten. It is crucial to verify your equipment's requirements, as fuel gases typically utilize Left Hand (LH) threads to prevent dangerous cross-connections. This specific part is strictly for Right Hand applications.
