CGA 580 to CGA 590 Cylinder Adaptor - Inert Gas to Industrial Air

Connect Your Air Regulator to Nitrogen Tanks with Ease

In the shop, versatility is key. Sometimes you need to run pneumatic tools, check for leaks in an AC system, or purge a line, and the best gas for the job is dry Nitrogen. However, your dedicated regulator might be set up for Industrial Air (CGA 590). That's where the Western Enterprises 846 Adaptor comes in. This handy piece of brass hardware allows you to screw a standard Industrial Air regulator directly onto a Nitrogen, Argon, or Helium cylinder (CGA 580). It’s a simple, rugged solution that saves you from having to buy a dedicated regulator for every single gas type you might use for pressure testing or general shop air applications.

Built by Western Enterprises, a brand known for making fittings that last, this adaptor is solid brass. It isn't a cheap, flimsy part that will strip out after a few uses. It’s machined to handle up to 3000 PSI, meaning it can handle the pressure of a full cylinder without breaking a sweat. The threads are cut cleanly and precisely, so you don't have to fight with it to get it seated on the tank or to get your regulator attached. A good seal is crucial when you are dealing with high-pressure cylinders, and this adaptor delivers a tight, leak-free connection every time, provided your O-rings and seating surfaces are clean.

Using the 846 is straightforward. The "tank side" of the adaptor has the standard CGA 580 male fitting that goes right into your inert gas cylinder. The "regulator side" mimics a CGA 590 cylinder valve, allowing you to thread your air regulator right on. This is perfect for mobile repair trucks, HVAC technicians, and fabricators who use nitrogen for purging welds or pressure testing assemblies but want to utilize their existing air regulation equipment. It’s a small part that solves a big headache.

Remember, while this adaptor lets you physically connect the two, always make sure you know what gas is in the tank and that your equipment is rated for it. This adaptor is designed for non-flammable, non-corrosive gases. It’s a must-have for any welder or tradesman who needs to adapt on the fly and keep the work moving. Toss one in your toolbox, and you'll be ready for whatever the job throws at you.
