Pipe Thread Guide
The OD or Outside Diameter is the measurement across the end of the pipe. This table compares the actual thread outside diameter to the nominal sizing in metric or imperial.
The easiest way to measure piping is by directly measuring across the widest part of the thread. Calipers can be useful for this especially when the pipe end is uneven or inaccessible.
Please note this guide is intended as guidance only. If you require any advice on threads or anything else please email us oninfo@waterlineproducts.co.uk.
