For eliminate costly weld rejects and maximize productivity
Eliminate costly weld rejects and maximize productivity with the G.A.L. Gage Co. Cat # 2 Economy Single Purpose Hi-Lo Welding Gauge. Often referred to as the wire-type Hi-Lo gauge, this compact, pocket-sized inspection tool is specifically engineered for pipe fitters and welding inspectors. It allows you to quickly check internal high-lo misalignments to ensure compliance with strict code requirements—especially in piping applications where the backside of the weld is inaccessible. Featuring a tapered section for precise root gap verification, this reliable instrument ensures precise joint fit-up every time. Available in customizable Inch (Imperial) or Metric scale options.
The G.A.L. Gage Co. Cat # 2 Economy Single Purpose Hi-Lo Welding Gauge is also included as a component in several comprehensive welder and inspector kits featured in the Related Products section below.

How to Use
- Check Internal Alignment (Hi-Lo): Insert the gauge legs into the internal root opening of the pipe joint. Read the mismatch indicator to verify whether the internal alignment meets allowable tolerances, preventing high-low mismatch defects
- Measure Root Weld Gap: Use the tapered wire-type section of the gauge to measure the root opening (fit-up gap) between pipe ends before tacking or final welding
- Verify Dimensions: Read the clearly engraved imperial or metric scale directly from the tool face to confirm that the gap and alignment satisfy code specifications
- Secure Settings: Utilize the built-in retaining screw mechanism to hold measurements in place for secondary reference or documentation when needed
