CGA580-1P - Miller CGA 580 Regulator Inlet Nut Plated

Reliable Regulator Repair with the Miller CGA580-1P

Keep your welding operations running smoothly with the Miller CGA580-1P Nut, Plated. If you are a TIG welder working with Argon or a maintenance pro handling Nitrogen purging equipment, you know that the connection between your regulator and the gas cylinder is the lifeline of your process. Over time, the threads on your regulator nut can become worn, crossed, or damaged from frequent cylinder changes. A compromised nut isn't just an annoyance; it's a safety hazard and a source of costly gas leaks. This genuine Miller replacement part allows you to restore your regulator's inlet connection to factory-new condition without buying a whole new regulator.

The CGA 580 connection is the standard for inert gases, making this nut compatible with cylinders containing Argon, Helium, and Nitrogen. Whether you are setting up a MIG welder for aluminum (using Argon) or a TIG machine for stainless steel, this nut is the hardware that secures your gas supply. The plated finish on this Miller nut offers superior durability compared to bare brass alternatives. It stands up better to the wear and tear of the shop environment, resisting rust and corrosion that can occur in humid conditions or outdoor job sites. The hex design is standard, allowing you to use your existing regulator wrench or crescent wrench for a tight, secure fit.

Why Choose Genuine Miller Parts?
When dealing with high-pressure gas, quality matters. Miller Electric is a leader in the welding industry, and their OEM parts are manufactured to strict quality control standards. Using a generic nut might save pennies, but it could cost you in wasted gas or damaged cylinder valves if the threads aren't cut perfectly. This nut is designed to thread smoothly into the cylinder valve, pulling the nipple tight against the seat to create a leak-proof seal. This ensures that your shielding gas goes exactly where it's needed—the weld puddle—rather than leaking out at the tank.

Installation is straightforward. Simply remove the old nut from your regulator stem (this may require removing the nipple if it's a captive design, or sliding it off if the nipple is removable), slide the new CGA580-1P nut on, and you are ready to connect to a fresh cylinder. It's a smart item to keep in your spare parts kit. Don't let a stripped nut stop production; keep a Miller CGA580-1P on hand for immediate repairs.
