Overview
The Praxair PRS27108 CGA-320 to CGA-580 brass adaptor is a precision-engineered cylinder-to-regulator adapter designed for oxy-fuel welding and cutting operations. This adaptor solves mating surface incompatibilities when connecting CGA-320 cylinders (typically used for COâ‚‚ and inert gases) to CGA-580 regulators (standard nitrogen and mixed gas service). The brass construction ensures durability and corrosion resistance in demanding industrial environments.
Key Features
- Converts CGA-320 cylinder threads to CGA-580 regulator threads

- Rated for pressures up to 200 psig (1400 kPa)
- Designed for oxy-acetylene and inert gas welding/cutting systems
- Praxair ProStar equipment compatibility
- Simple, reliable one-piece design
