What Thread? — G Pipe Threads

Not sure which size a threaded connection is? Choose an outside thread or the opening of a threaded nut, measure its diameter and enter the value. The app compares it with selected G-thread reference sizes and suggests a size in inches. • Separate male and female measurement references. • Millimetres or centimetres; decimal dot or comma. • Drawings showing where to measure. • 9 sizes: G ⅛, ¼, ⅜, ½, ¾, 1, 1¼, 1½ and 2 inches. • Advice on looking for a male or female mating thread. • Show a description in the shop or copy it. • Reference table, data source and checked date in the app. • Polish, German and English. Size lookup works offline without an account. Your last measurement and settings are stored locally. Ads, privacy forms and opening the external source need internet. A small advertising banner appears at the bottom. Important: selected parallel G threads (ISO 228-1) only. Metric threads, faucet aerators and other thread families are not supported. Diameter alone confirms neither thread type nor part compatibility. Results are approximate. Check thread pitch, sealing method and both connection ends before buying. The ±1 mm search window helps compare ruler measurements; it is not an installation tolerance.

First release. Find a possible G thread size from the outside diameter or a threaded nut opening. Measurement drawings, millimetres and centimetres, 9 reference sizes and Polish, German and English. Size lookup works offline.
