510XLRF6 - Dixon CGA 510 Acetylene Regulator Inlet Stem 4.5-Inch

Technical Overview of the Dixon 510XLRF6 Acetylene Stem

The Dixon 510XLRF6 is a specialized gas apparatus component designed for the inlet side of acetylene pressure regulators. Manufactured to strict Compressed Gas Association (CGA) standards, this stem features a CGA 510 profile, which is the standard connection for acetylene and certain other fuel gas cylinders in industrial welding applications. The stem measures 4.5 inches in length, providing the necessary extension from the regulator body to the cylinder valve, ensuring that the regulator gauges and body do not interfere with the cylinder collar or other obstructions.

Constructed from high-quality brass, this stem is engineered to withstand the mechanical stresses of frequent cylinder changes and the chemical properties of acetylene gas. Brass is the preferred material for these components due to its non-sparking properties and resistance to corrosion. The sealing surface is precision-machined to mate perfectly with the corresponding CGA 510 nut and cylinder valve outlet, creating a gas-tight seal that is critical for safety in oxy-fuel operations. As an acetylene component, it utilizes left-hand threads (indicated by the notched nut, though this SKU refers specifically to the stem) to prevent cross-connection with oxygen or inert gas systems, adhering to safety protocols.

This component is essential for MRO (Maintenance, Repair, and Operations) professionals tasked with refurbishing welding regulators or assembling custom gas manifolds. It serves as the primary conduit for high-pressure gas entering the regulator, making its structural integrity paramount. The 4.5-inch length is a standard dimension that fits a wide variety of regulator brands and models, offering versatility in repair scenarios. Whether replacing a damaged stem due to thread wear or impact, or configuring a new setup, the Dixon 510XLRF6 provides the reliability required for industrial gas control systems.
