CGA200-1 - Miller CGA 200 Acetylene Inlet Nut for MC Tanks

Secure Your Acetylene Connection with Genuine Miller Parts

When you are out in the field with your portable torch kit, the last thing you need is a leaky connection on your acetylene tank. The Miller CGA200-1 Inlet Nut is the exact replacement part you need to keep your "MC" tank regulator hooked up and running safely. Designed specifically for the smaller Acetylene MC cylinders often used by plumbers, HVAC techs, and hobbyists, this nut ensures you get a tight, secure seal every time you swap out a tank. Don't risk your safety or waste expensive gas with stripped or worn-out fittings—trust Miller to keep your flame steady and your gear secure.

We know that brass fittings take a beating. Between being tossed in the back of a truck and the constant wrenching during tank changes, the corners of your inlet nuts can get rounded off, making them a pain to tighten properly. This Miller replacement nut is built tough from solid brass, giving you fresh, sharp hex edges that your wrench can grip easily. It features the standard CGA 200 right-hand thread pattern, so it spins smoothly onto any standard MC cylinder valve without binding or cross-threading. It’s a small part, but it plays a huge role in the safety of your oxy-fuel setup.

Using genuine Miller parts means you aren't guessing about quality. This isn't a cheap knock-off that might crack under pressure; it's the same hardware that comes on high-end Miller and Smith Equipment regulators. Whether you are fixing up an old torch set or just keeping a spare in your toolbox for emergencies, this inlet nut is cheap insurance against downtime. It pairs perfectly with your existing regulator nipple to create a metal-to-metal seal that holds pressure reliably, letting you focus on your braze or weld instead of sniffing for leaks.

Upgrade your regulator maintenance game today. If your current nut is looking gnarly or you are building up a custom manifold for portable work, the CGA200-1 is the industry-standard solution. Remember, CGA 200 is specifically for those small MC tanks—if you run B-tanks or large cylinders, you'll need a different size, but for the portable MC crowd, this is the one. Grab a couple for your kit and weld with confidence knowing your connections are solid.
