CGA-320 to CGA-580 Brass Cylinder Adaptor for Inert Gas Regulators

Connect Your Argon Regulator to CO2 Tanks with Ease

Every welder knows the hassle of switching between shielding gases. You've got your MIG machine set up with a nice flowmeter for Argon/CO2 mix, but a job comes in that requires straight CO2 for better penetration on thick steel. The problem? Your regulator has a CGA-580 nut (the standard for Argon/Mix), but your straight CO2 cylinder has a CGA-320 valve. Instead of buying a completely separate regulator just for CO2, the Western Enterprises WES806 Cylinder Adaptor is the smart, cost-effective solution. This solid brass fitting screws directly onto the CO2 tank and gives you the male threads you need to attach your existing Argon regulator.

Built tough for the shop environment, this adaptor isn't some cheap, flimsy part. It's machined from solid brass right here in the USA, giving it the weight and durability you expect from professional-grade equipment. It handles up to 3000 PSI, so it's more than capable of handling full cylinders safely. The large 1-1/8" hex design means you can get a good grip on it with your adjustable wrench, ensuring you can tighten it down properly to prevent leaks. It's a simple tool that solves a common headache, keeping your downtime to a minimum so you can get back to burning wire.

Using the WES806 is straightforward, but safety is always priority number one. Since you are adapting to a CGA-320 valve, remember that the CO2 side typically requires a plastic washer to seal properly—make sure that washer is in place before tightening the adaptor to the cylinder. Once the adaptor is on, your standard regulator screws onto the other side just like it would on an Argon bottle. Always perform a quick leak check with soapy water or leak detection fluid after hooking everything up. It takes ten seconds and ensures you aren't venting expensive gas or creating a hazard.

This adaptor is perfect for mobile welders, fabrication shops, and maintenance crews who need versatility. It allows you to maximize the utility of your existing regulators and flowmeters. Whether you are experimenting with different shielding gases or just need to use a CO2 cylinder in a pinch, having a WES806 in your toolbox can save the day. It's a small investment that adds a ton of flexibility to your welding cart, ensuring you're never stuck with the wrong regulator for the tank you have on hand.
