16433 - Miller Replacement Flowtube for Argon/CO2/Helium Regulators

Precision Shielding Gas Regulation

The Miller 16433 Flowtube is a critical component for maintaining the accuracy and safety of your welding gas regulation system. Designed specifically for Miller and compatible Smith flowmeters, this replacement tube ensures that your shielding gas flow rates are read correctly, which is fundamental to achieving high-quality welds. Inconsistent gas flow can lead to porosity, oxidation, and weak weld joints; therefore, maintaining the integrity of your flowmeter with genuine OEM parts is essential for professional fabrication standards.

Durable Polycarbonate Construction

Unlike traditional glass tubes that are prone to shattering upon impact, this flowtube is manufactured from high-grade polycarbonate. This material choice provides exceptional durability and impact resistance, making it well-suited for the rigors of industrial environments where equipment is frequently moved or subject to accidental knocks. The clarity of the polycarbonate ensures that the flow ball is visible from a distance, allowing operators to monitor gas usage effectively without straining to read the scale.

Multi-Gas Calibration

This specific model is calibrated for use with three of the most common shielding gases in the welding industry: Argon (Ar), Carbon Dioxide (CO2), and Helium (Hel). The tube features distinct scales for each gas, allowing for versatile application across different welding processes such as MIG (GMAW) and TIG (GTAW). The calibration is set for a 30 PSI inlet pressure, which is a standard compensation pressure for many flowmeter regulators, ensuring that the reading remains accurate even if there are slight fluctuations in line pressure.

Maintenance and Compatibility

Over time, flowtubes can become clouded due to contaminants in the gas supply or damaged by UV exposure and physical stress. Replacing a damaged or illegible tube with the Miller 16433 restores the functionality of your regulator immediately. It is designed to fit specific Miller flowmeter bodies seamlessly, ensuring a gas-tight seal and proper ball float operation. When installing, ensure that all O-rings and seals are also inspected to prevent leaks.
