Capillary Tube Gauge Double Scale Copper Tube Gauge Precision Sizing Measuring Tool

Double Measurement: This capillary tube gauge is a practical measuring tool for checking both inner and outer tube diameters in one compact instrument, helping you work faster with less guesswork.

Accurate Fit Checking: As a tube gauge and tube gauge, it provides clearly marked slots and reference sizes so you can quickly match tubing to the correct opening and confirm the fit before cutting or installing.

Metric and British Markings: The capillary tube gauge includes both metric and British graduations, making it easier to read measurements across different job standards without switching tools.

Copper Tube Compatibility: Designed as a copper tube gauge, it is especially useful for refrigeration and air-conditioning tubing work area consistent diameter checks matter for clean, reliable assembly.

Workshop Efficiency: With this capillary tube gauge, you can measure tubing more confidently during repair, fabrication, or maintenance tasks, saving time and reducing sizing errors on the bench or in the field.
