Measuring pipe thread size to find the right thread type can be confusing. Thread dimensions are considered a nominal size and don’t match standard units of measurement. Using the proper pipe thread type is crucial for maintaining and installing equipment, so helping you determine what pipe thread you need is important to us. This page is set up to help you understand the different types of threads used and to identify the threading you need.
