OVERVIEW

Precision Brass Adapter for Inert Gas Systems

The DIXADAPTOR12INERT is a specialized industrial gas fitting designed to facilitate the connection between standard 1/2-inch National Pipe Taper (NPT) threads and standard Inert Gas connections. Manufactured from high-quality brass, this adapter ensures a secure, leak-free seal and offers excellent resistance to corrosion and wear, making it suitable for long-term use in demanding welding and industrial environments.

This component is essential for facility managers and welding technicians setting up gas distribution manifolds, bulk gas systems, or custom machinery. It effectively bridges the gap between permanent piping infrastructure and detachable gas equipment such as regulators, flowmeters, or hose assemblies. The adapter features a standard 1/2" NPT thread on one side and a 5/8"-18 RH (Right Hand) thread—commonly associated with inert gas fittings like CGA 032 or CGA 580 outlets—on the other.

Proper installation of this adapter ensures the safe and efficient flow of shielding gases such as Argon, Helium, and Nitrogen, as well as welding mixtures. Its robust construction withstands standard working pressures found in shop air and gas delivery systems. Whether you are retrofitting an existing station or building a new gas drop, this adapter provides the compatibility and reliability required for professional applications.

FAQ

The pipe side features a 1/2" NPT (National Pipe Taper) thread, which is a standard size for industrial piping.

This adapter is designed for Inert gases such as Argon, Helium, and Nitrogen. It uses the standard 5/8"-18 RH thread common for these gas services.

No, this adapter is specified for Inert gases. Oxygen fittings typically require different threads and strict cleaning for oxygen service to prevent combustion hazards.

You should use Teflon tape or a suitable pipe thread sealant on the 1/2" NPT side to ensure a leak-proof seal. The inert gas side typically seals via a mechanical seat or washer depending on the mating fitting.

The adapter is machined from solid brass, providing durability and compatibility with most industrial gases.

No, propane fittings usually use left-hand threads (fuel gas) to distinguish them from inert and oxygen lines. This adapter has right-hand threads.

The adapter is rated for standard compressed gas working pressures typically found in welding distribution systems (usually up to 200-300 PSI for line pressure), but the NPT connection limit depends on installation quality.
