Threaded Pipe Ring Gauges

0 products

Threaded pipe ring gauges are precision tools designed for inspecting external straight and tapered pipe threads. The straight pipe variants function as Go/No-Go gauges, enabling quick pass/fail assessments by testing the lower and upper tolerance limits, respectively. Tapered versions include internally threaded L-1 and L-2 rings, along with smooth, non-threaded 6-Step models. Each gauge is clearly labeled with its nominal size and type, and defaults to right-handed threading unless specified.
