639571 - Victor Replacement Flowmeter Tube 1/4-33-G-5 Glass

Precision Replacement Component for Gas Regulation

The ESAB/Victor 639571 Tube Meter 1/4-33-G-5 GLS is a specialized replacement component designed to restore the operational accuracy of industrial flowmeters. In gas shielding applications, the integrity of the flow measurement system is critical for maintaining weld quality and process consistency. This tube is manufactured from high-quality, transparent glass, ensuring optimal visibility of the float mechanism and the calibrated scale under various lighting conditions.

Engineered to the specific 1/4-33-G-5 standard, this tube ensures a precise fit within compatible regulator bodies, preventing gas leaks and ensuring correct back-pressure handling. The scale is permanently marked to resist fading over time, allowing operators to verify flow rates with confidence. For maintenance personnel and facility managers, stocking replacement tubes like the 639571 is a proactive measure to minimize downtime caused by accidental impact or thermal shock to regulator equipment.

This component is part of the broader Victor gas equipment ecosystem, known for reliability in heavy-duty industrial environments. Whether used in MIG, TIG, or laboratory gas applications, this replacement tube maintains the manufacturer's original performance specifications. Installation should always be performed by qualified personnel to ensure proper seating and leak-free operation.
