15178 - Miller Replacement Red Glass Flowmeter Float 5/16 Inch

Precision Replacement for Gas Flow Measurement

The Miller 15178 Float is a specialized replacement component designed for Miller flowmeters and regulators. Constructed from high-quality red glass, this float serves as the critical indicator within the flow tube (rotameter), allowing operators to visually verify and adjust the flow rate of shielding gases such as Argon, CO2, or Helium. Maintaining the accuracy of your flowmeter is essential for industrial welding applications, as incorrect gas flow can lead to porosity, oxidation, and poor weld quality.

With a precise diameter of 5/16 of an inch, this float is engineered to match the calibration of specific Miller flow tubes. The specific density and shape of the glass ensure that it rises linearly with the gas velocity, providing a reliable reading on the scale. Over time, floats can become chipped, lost during cleaning, or obscured by contaminants. Replacing the float with a genuine Miller part restores the functionality of the regulator assembly without the need to replace the entire unit.

This component is compatible with various Miller industrial gas equipment setups. It is chemically inert to standard welding gases, ensuring long-term durability and consistent performance in professional environments. Whether performing maintenance on a shop floor regulator or refurbishing older equipment, the Miller 15178 ensures your gas delivery system operates within manufacturer specifications.
