1000-0285 - Victor FM373-LH Shielding Gas Flowmeter Assembly Left Inlet

Precision Gas Control with the Victor FM373-LH

For professional welders, consistent shielding gas coverage is the difference between a perfect bead and a porous failure. The Victor FM373-LH Flowmeter Assembly is built to give you that consistency, day in and day out. Whether you are running a TIG root pass on stainless steel or pushing heavy MIG wire on structural carbon, knowing exactly how much gas is hitting your puddle is vital. This unit is the legendary Victor "square block" style flowmeter, known throughout the industry for its reliability and ease of reading.

What sets this specific model apart is its Left Side Inlet. Not every shop setup is the same; sometimes your regulator or manifold drop is positioned in a way that makes a standard bottom-inlet flowmeter impossible to mount or read. The FM373-LH solves this problem, allowing you to mount the meter directly to ports situated on the left, keeping your gauges visible and your hoses routed cleanly. No more twisting your neck to read a flow tube turned the wrong way.

Built for the Shop Floor

We know that equipment takes a beating in a real shop. That’s why Victor uses a high-strength Lexan flow tube instead of fragile glass. If you accidentally knock it with a wrench or a piece of stock, it’s built to survive. The scales are clearly marked in black on the tube itself, showing flow rates for Argon, Helium, and CO2. You don't need a conversion chart; just look at the ball and adjust the knob. The adjustment knob is smooth and sensitive, allowing you to set your flow from a whisper to a roar with precision.

Key Benefits for the Welder

• Versatility: One meter covers your three main gases—Argon, CO2, and Helium.
• Clarity: The tube is easy to read even from a distance or through a welding helmet lens.
• Durability: Brass body and shatter-resistant tube mean this tool lasts for years.
• Gas Savings: Accurate metering prevents the "guess and check" method, saving you money on wasted gas.

Upgrade your gas delivery system with the Victor FM373-LH. It’s a small investment that pays off in better weld quality and less frustration with your equipment setup.
