The Thread Gauge 5 Pack is a compact and dependable tool for measuring internal and external pipe thread sizes across NPT, BSPP and metric ranges. It improves accuracy, saves time and supports confident installations, making it essential for technical and maintenance professionals.
Each gauge is clearly marked and crafted for straightforward use, allowing you to measure NPT, BSPP and metric sizes without complications. The dual sided design separates metric from NPT and BSPP measurements to ensure smooth operation and improved clarity. Whether you are handling pipes, fittings or machinery connections, the Thread Gauge 5 Pack gives you a fast way to confirm the correct size before you commit to installation or repair work.
This tool is especially useful when working in environments where documentation is incomplete or parts have been replaced over time. Instead of guessing or trial and error, you can quickly verify the approximate size and reduce the risk of costly rework. Built for accuracy and durability, each gauge fits easily into a pocket or toolbag, making it an essential companion for routine inspections and preventive maintenance tasks.
The thread gauge provides a practical way to identify the general size of a male or female pipe thread. For internal threads, insert the pointed end into the opening and align the point as close to the centreline as possible. The correct size is the measurement line that meets the outermost visible thread. For external threads, place the V shaped end over the threads and read the measurement that aligns with the thread circle. This gives a reliable size approximation suitable for most field applications.
This thread gauge is intended solely for inspection and size verification. It cannot distinguish between different thread types or pitches. Measurements may vary if the gauge is used incorrectly. The manufacturer is not responsible for damage or errors that result from improper handling, misuse or failure to follow operating instructions. Always verify critical thread measurements against approved reference standards before completing any installation or repair.
