0973-0003 - Victor CGA 580 Brass Inlet Nut for Inert Gas Regulators

Reliable Replacement for Your Shielding Gas Setup

Keep your welding operations running smoothly with the Victor 0973-0003 Brass Nut. If you are a TIG or MIG welder, you know that a secure connection to your shielding gas cylinder is the lifeline of your weld quality. Over time, the threads on your regulator nut can become stripped, nicked, or worn down from frequent tank swaps. A compromised nut makes it difficult to tighten your regulator properly, leading to gas leaks that waste expensive Argon or Helium and can cause porosity in your welds due to insufficient shielding coverage.

This genuine Victor replacement nut is the perfect fix for your worn-out gear. Designed for CGA 580 connections—the standard for Argon, Nitrogen, and Helium tanks—it fits perfectly on most inert gas flowmeters and regulators. Made from solid brass, it is built to handle the wear and tear of the shop environment. It threads smoothly onto the cylinder valve, ensuring you can get a tight seal every time without fighting cross-threaded fittings.

Don't rely on questionable generic parts for your high-pressure gas connections. Using the correct Victor nut ensures that your regulator sits square on the valve, protecting the nipple seating surface and preventing leaks. Whether you are setting up a new tank of pure Argon for aluminum TIG work or hooking up a Nitrogen purge line, this nut is an essential spare part for your toolbox. It allows you to repair your regulator stem quickly and get back to laying beads.
