The AGS Brake Line Fitting Gauges come in both SAE/Inch and ISO/Metric versions. The Brake Line Fitting Gauge is an accurate and easy-to-use thread checker for the most common thread sizes found in automotive braking systems.

  • Conveniently assembled onto a wire loop, it is especially well suited for distinguishing between similar inch and metric threads. This tool is a great addition for Auto, Motorcycle, Marine, ATV or RV Repair Shops.
  • Each size has a male and female end checker on the same gauge.
  • Thread sizes are permanently stamped onto each gauge.
  • Inch gauges are clear zinc plated, metric gauges are black oxide.
  • A wire cable with plastic coated loop at each end provides convenient hanging in many locations.
  • Each gauge rotates freely on the wire cable for quick and easy thread verification.
