OVERVIEW

Western Enterprises 843: CGA-346 to CGA-590 Adapter

Streamline your welding and industrial gas setup with the Western Enterprises 843 Cylinder Adapter. In the diverse world of compressed gas fittings, encountering mismatched connections is a common challenge. This adapter provides a safe and professional solution, converting a CGA-346 cylinder valve (commonly found on industrial air cylinders) to accept a CGA-590 regulator connection. This simple yet robust fitting eliminates the downtime associated with sourcing new regulators or swapping cylinders.

Precision Engineering for Leak-Free Seals

Gas leaks are not just wasteful; they are a safety hazard. The Western 843 adapter is crafted with precision-machined threads that ensure a secure engagement with both the cylinder valve and the regulator nut. Made from high-grade brass, the adapter withstands the rigors of daily shop use, resisting deformation and thread galling. Its solid construction supports service pressures up to 3000 PSIG, providing peace of mind during high-pressure operations.

Application and Compatibility

Designed specifically for Air service, this adapter is a must-have for shops that utilize compressed air for pneumatic tools, plasma cutting, or general fabrication tasks. The CGA-346 connection is the standard for industrial air, while CGA-590 is often found on specific high-purity or industrial air regulators. By keeping a Western 843 adapter in your toolbox, you ensure that your shop is prepared for varying cylinder supplies without interrupting workflow.

Installation and Maintenance

Installing the Western 843 is straightforward. Simply thread the adapter onto the cylinder valve (CGA-346 side) and tighten securely with a wrench. Then, attach your CGA-590 regulator to the adapter's outlet. Always ensure all sealing surfaces are clean and free of oil or debris before connection. As with all gas equipment, inspect the adapter regularly for signs of wear or damage to ensure continued safe operation. Trust Western Enterprises for fittings that deliver consistent performance and safety.

FAQ

The Western Enterprises 843 adapter is designed to connect a regulator with a CGA-590 inlet to a gas cylinder equipped with a CGA-346 valve.

This adapter is intended for use with Industrial Air. Both CGA-346 and CGA-590 connections are associated with air service in specific contexts.

The adapter is rated for service pressures up to 3000 PSIG, which is standard for these CGA connections.

No, you should never use this adapter for Oxygen. Oxygen requires specific CGA-540 connections and materials cleaned for oxygen service to prevent combustion hazards.

It is manufactured from solid brass, which provides excellent durability and corrosion resistance for industrial gas applications.

Generally, CGA fittings are designed to seal via metal-to-metal contact or specific seating surfaces. You should not use Teflon tape on the CGA connection threads unless specified by the manufacturer, as loose tape can clog regulators.

CGA-346 cylinder valves are typically male threads, so the cylinder side of this adapter (which mimics the regulator nut) would attach to that. However, adapters are defined by what they connect: Cylinder (CGA-346) to Regulator (CGA-590).

CGA standards have evolved, and different numbers can denote different pressure ratings or purity levels. CGA-346 and CGA-590 are both used for air, and this adapter helps bridge the compatibility gap between older and newer equipment or different supply standards.
