22173 - Replacement Flowmeter Outer Tube Cover

Reliable Protection for Precision Gas Metering

The ESAB Flowmeter Outer Tube (Part Number 22173) is a critical replacement component designed to maintain the integrity and functionality of industrial gas regulators. In welding and industrial applications, the flowmeter is essential for accurately monitoring shielding gas flow rates, which directly impacts weld quality. This outer tube serves as the primary protective barrier for the delicate inner flow tube and the floating ball mechanism.

Manufactured from high-grade, impact-resistant polycarbonate, this tube is engineered to withstand the rigors of the shop floor. Over time, original tubes can become clouded due to exposure to fumes, UV light, or chemical splashes, or they may crack from accidental impact. A compromised outer tube not only obscures the technician's view of the flow rate but can also present a safety hazard if the structural integrity is lost under pressure. This replacement part restores the unit to optimal condition, ensuring that flow readings are legible and the internal components are shielded from physical damage.

Installation is straightforward, designed to fit specific ESAB and compatible flowmeter bodies. By replacing a damaged outer tube promptly, maintenance personnel can extend the service life of expensive regulator assemblies without the need for total replacement. This component is compatible with standard inert gases used in welding, including Argon, CO2, and Helium mixtures.
