Miller Replacement Flowtube for Argon/CO2/Helium Regulators

Restore Your Flowmeter's Accuracy

Is your flowmeter tube cracked, cloudy, or just impossible to read? Don't guess your gas settings—that's a recipe for bad welds and wasted gas. The Miller 16433 Flowtube is the direct replacement you need to get your regulator back in top shape. Whether you dropped your regulator or the shop gremlins got to it, this replacement part swaps out easily so you can get back to laying beads with confidence. Knowing exactly how much gas you are pushing is the first step to a perfect weld.

Built for the Shop Environment

We know that welding shops aren't delicate places. That's why this tube is made from tough polycarbonate, not fragile glass. It can take a bump without shattering, keeping you safe and keeping your equipment running. The clear plastic construction stays transparent, giving you a distinct view of the floating ball so you can dial in your CFH (Cubic Feet per Hour) precisely. No more squinting through a yellowed or scratched tube.

One Tube, Three Gases

Versatility is key when you are switching between processes. This flowtube comes marked with scales for Argon, CO2, and Helium. Whether you are TIG welding aluminum with pure Argon, MIG welding steel with C25, or using a Helium mix for heavy penetration, this single tube has you covered. It is calibrated for 30 PSI systems, which covers a vast majority of standard shop setups.

Quick and Easy Repair

You don't need to buy a whole new regulator just because the tube is damaged. This is a cost-effective fix that takes minutes to install. Simply disassemble the flowmeter housing, swap out the old tube for this fresh Miller 16433, and you are ready to go. Keep a spare in your maintenance kit so a cracked tube never shuts down your production line.
