OVERVIEW

Reliable Gas Connection Solutions with Western Enterprises

The Western Enterprises 843 Cylinder Adapter is an essential component for industrial gas management, specifically designed to bridge the gap between different Compressed Gas Association (CGA) standards. This precision-engineered fitting allows operators to connect a regulator with a CGA-590 inlet to a cylinder equipped with a CGA-346 valve. Primarily used for Industrial Air applications, this adapter ensures that your existing equipment remains compatible and functional without the need for costly regulator replacements.

Heavy-Duty Brass Construction

Safety and durability are paramount when dealing with compressed gases. The Western Enterprises 843 is machined from solid brass, offering superior resistance to corrosion and wear. The high-quality material ensures that the threads remain sharp and effective over repeated uses, maintaining a tight, leak-proof seal that is critical for maintaining system pressure and safety. Brass is the industry standard for non-corrosive gas fittings due to its spark resistance and mechanical strength.

Specifications and Safety

This adapter is rated for pressures up to 3000 PSIG, making it suitable for standard high-pressure industrial air cylinders. It is crucial to verify that both the cylinder and the regulator are rated for the same gas service before use. While adapters provide flexibility, they must be used responsibly. The CGA-346 to CGA-590 conversion is specific to air service; users should never attempt to use this adapter for incompatible gases like oxygen or fuel gases, as this could create hazardous conditions.

Why Choose Western Enterprises?

Western Enterprises has been a trusted name in the compressed gas industry for decades. Their fittings and adapters are manufactured to strict tolerances, ensuring compliance with industry safety standards. When you choose the Western 843 adapter, you are investing in a product that guarantees reliability, ease of installation, and long-term performance in demanding industrial environments.

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.
