OVERVIEW

Clear Vision for Perfect Shielding

There is nothing more frustrating than trying to set your gas flow on a cloudy, cracked, or dirty flowmeter. Guessing your gas flow is a recipe for disaster—too little and you get porosity; too much and you waste money while potentially causing turbulence that pulls air into the weld pool. The ESAB 32144 Replacement Inner Flowmeter Tube is your solution to getting back to precision welding. Designed specifically for CO2, this tube gives you the confidence that the flow rate you see is the flow rate you are actually getting at the nozzle.

Accidents happen in the shop. A regulator gets knocked over, or a heavy cable swings into the gauge, and suddenly you have a cracked tube. You don't need to throw away the whole regulator. By simply swapping out the damaged inner tube with this genuine replacement, you can make your flowmeter look and work like new again. The scale is printed with bold, easy-to-read numbers, so you don't have to squint through your helmet or safety glasses to check your levels. It is built tough to handle the daily grind of a welding environment, resisting yellowing and cracking under normal use.

This tube is calibrated strictly for CO2. Since CO2 is heavier than Argon, using the wrong tube can lead to inaccurate settings. Using this dedicated CO2 tube ensures your settings are true, helping you dial in that perfect arc. Whether you are running flux-cored wire or solid wire with straight CO2, this replacement part ensures your shielding gas coverage is consistent. Keep one in your shop's spare parts drawer so you are never down for long if a mishap occurs. It’s a small part that plays a huge role in the quality of your finished work.

FAQ

No, this specific tube (32144) is calibrated for Carbon Dioxide (CO2). Because CO2 has a different density than Argon, using this tube for Argon would result in inaccurate flow readings. You should use a tube specifically calibrated for the gas you are using.

Generally, you need to unscrew the outer protective cover of your flowmeter, remove the old tube and float, and seat the new tube in place. Ensure the O-rings are properly positioned and not damaged before reassembling to prevent leaks.

Typically, this part number refers to the inner tube only. You may need to reuse your existing float ball or purchase one separately if it is missing.

The tube is manufactured from high-impact polycarbonate or similar durable plastic, designed to resist breakage and maintain optical clarity in industrial environments.

Flowmeter tubes can become cloudy over time due to exposure to UV light, chemical contaminants in the shop air, or impurities in the gas supply. A cloudy tube should be replaced to ensure accurate readings.

No, it is designed to fit specific ESAB and Victor-style flowmeters. Flowmeter tubes vary in length and diameter, so it is important to check your equipment's parts manual to verify that part number 32144 is the correct replacement.

For most ball-style flowmeters, the flow rate is read at the center of the ball. Align the center of the floating ball with the line on the scale to determine your Cubic Feet Per Hour (CFH).

No, this is a low-pressure flowmeter tube designed for the output side of a regulator, typically operating at pressures below 50-80 PSI depending on the regulator design.
