OVERVIEW

Connect Your Gas Gear with Confidence

When you're setting up your welding rig or gas delivery system, having the right fittings is the difference between a job well done and a headache. The Victor A414 Inert Gas Adapter (0950-0163) is the solid brass connector you need to bridge the gap between your equipment. If you have a regulator or machine port with a 1/4" NPT female thread and need to hook up a standard inert gas hose or fitting, this is the part that makes it happen.

Victor is a name welders trust, and this adapter lives up to that reputation. It's machined from durable brass, so you don't have to worry about stripped threads or cracking under pressure. The 1/4" NPT Male end screws tight into your manifold or regulator body, while the 5/8"-18 "B" side is ready to accept your standard Argon or Helium hose connections. It's perfect for TIG and MIG setups where leak-free shielding gas flow is crucial for weld quality.

Don't waste time with cheap fittings that leak or don't fit quite right. This adapter ensures a tight, secure fit so you can turn on the gas and focus on laying beads. Whether you are repairing an old regulator, building a custom purge setup, or just need a spare in the toolbox for when things go sideways, the Victor A414 is a must-have accessory for any serious fabricator working with inert gases.

FAQ

The adapter features a 1/4" NPT Male thread on one side and a 5/8"-18 "B" size thread on the other.

No, this adapter is specified for Inert Gas service. Oxygen fittings typically use different thread standards (CGA 022 or similar) to prevent cross-connection.

It is manufactured from high-quality brass.

Yes, Argon is an inert gas, and this adapter is perfectly suitable for Argon connections using standard B-size fittings.

Yes, NPT (National Pipe Taper) threads generally require PTFE tape or a suitable thread sealant to ensure a leak-proof seal.

"B" size refers to the standard CGA connection size for welding hose fittings, which is 5/8"-18 threads.

The product description lists it as an adapter. Typically, if adapting from a regulator (NPT) to a hose, the B-size side would be Male to accept the Female hose nut, but verify your specific mating part requirements.

Yes, as long as your nitrogen equipment utilizes standard inert gas B-size connections and 1/4" NPT ports.
