OVERVIEW

ESAB 119X07 CGA 200 to CGA 520 Adapter

Maximize the utility of your gas equipment with the ESAB 119X07 Cylinder Adapter. This specialized fitting is designed to convert a CGA 520 cylinder outlet to a CGA 200 male connection. In practical terms, this allows you to mount a regulator intended for an "MC" acetylene tank onto a "B" acetylene tank. For welders and tradespeople who own regulators with the smaller CGA 200 nut but occasionally need to draw from larger B-style cylinders, this adapter is a cost-effective solution that negates the need for a second regulator.

The adapter is crafted from premium brass, the industry standard for fuel gas fittings due to its non-sparking properties and durability. The CGA 520 Female end connects securely to the external threads of the B-tank valve, while the CGA 200 Male end provides the necessary external threads for your MC regulator's nut. This seamless conversion maintains the integrity of the gas flow and ensures that your pressure regulation equipment functions correctly despite the change in cylinder source.

Compact and lightweight, the ESAB 119X07 is easy to store in a torch kit or toolbox. It is an indispensable accessory for workshops that manage multiple tank sizes or for field operators who need adaptability. Please note that this adapter is designed strictly for acetylene gas and adheres to the pressure ratings and safety protocols associated with fuel gas handling. Always ensure connections are tightened properly and leak-tested before operation.

FAQ

It adapts a CGA 520 cylinder valve (B tank) to accept a CGA 200 regulator connection (MC tank).

No, this adapter is designed specifically for acetylene connections and must not be used with oxygen or other high-pressure gases.

The adapter is made from solid brass, which is standard for fuel gas fittings due to its durability and non-sparking nature.

The CGA 520 Female side connects to the B-tank cylinder valve.

If your regulator has a CGA 200 nut (common on MC tank kits), yes, this adapter will allow you to use it on a B tank.

CGA connections typically rely on the metal-to-metal seal or specific washers depending on the exact fitting type; always check if your regulator requires a washer, but the adapter threads themselves are standard.

CGA 200 is the standard connection for small 'MC' acetylene tanks (10 cu ft), while CGA 520 is for 'B' tanks (40 cu ft). They have different thread sizes.

Yes, this is a genuine ESAB gas equipment accessory.
