E99-347C44 - Miller CGA 347 Stainless Steel Nut Replacement

Keep Your Air Systems Running Smoothly

When you are out in the shop or on the job site, the last thing you need is a stripped thread or a cracked fitting shutting down your operation. The Miller E99-347C44 Nut is your go-to replacement for CGA 347 high-pressure air connections. Built tough from stainless steel, this nut is designed to handle the heavy torque and high pressure associated with industrial air cylinders. Whether you are setting up a plasma cutting rig that requires high-pressure air or managing a breathing air manifold, this nut ensures your connections are solid and leak-free.

Why Stainless Steel Matters

You might see brass fittings everywhere, but when it comes to durability and longevity, stainless steel is in a league of its own. This Miller nut resists rounding off, meaning your wrench gets a good grip every time you swap a tank. It also stands up to rust and corrosion better than standard fittings, which is a huge plus if your equipment spends time on the back of a truck or in damp shop corners. The stainless construction gives you peace of mind knowing that the fitting holding back thousands of PSI is up to the task.

Direct Replacement for Miller Gear

Don't gamble with generic parts when it comes to high-pressure gas. This is a genuine Miller OEM part, meaning it fits exactly as it should. No fighting with threads, no wondering if it will seal properly. It is designed to work seamlessly with your existing Miller regulators and hoses that utilize the CGA 347 connection. It’s a small part, but it plays a huge role in the safety and efficiency of your setup.

Quick Fix for Worn Equipment

Over time, the threads on your regulator nuts can get banged up from constant use. If you notice any resistance when screwing it onto the cylinder, or if the threads look flat, it's time to swap it out. Keeping a spare Miller E99-347C44 in your toolbox is a smart move. It allows you to fix a bad connection on the spot without waiting for parts delivery, keeping your downtime to a minimum and your projects on schedule.
