Threaded Pipe Plug Gauges

0 products

Threaded pipe plug gauges, also referred to as pipe thread plug gauges or pipe plugs, are essential tools for inspecting and verifying the accuracy of internal straight and tapered pipe threads. Straight pipe plug gauges are specifically designed for assessing straight pipe threads, including NPSM, NPSF, and BSPP types. The Go and No-Go plug gauges ensure that internally threaded pipes meet tolerance standards by seamlessly fitting with the threads. For tapered pipe threads, L-1, L-3, and 6-Step gauges are utilized for precise tolerance verification, with L-1 and L-3 being threaded and the 6-Step gauge smooth. Each set comes with a double-ended Taperlock handle featuring both Go and No-Go gauge components. All gauges are clearly labeled with their nominal size and type, and are right-handed unless otherwise specified.
