Pipe Fitting Dimensions – Standards & Reference Guide

Pipe fittings are essential components in any piping system, enabling changes in direction, branching, or size changes. Accurate fitting dimensions are crucial for ensuring proper alignment, leak prevention, and system design. Industry standards like ASME B16.9 and B16.11 provide specifications for various fittings, including elbows, tees, reducers, caps, and other special components.

Engineers, designers, and procurement teams rely on these standardized dimensions for safe and efficient installation. This section provides quick access to detailed dimension charts for a wide range of fittings. Whether you are working on new projects, replacements, or maintenance, these tables help you get the right fitting dimensions for your application.

Each linked page contains measurements for nominal pipe sizes (NPS) from small bore to large diameter fittings. Explore the categories below to find the dimensions you need for your piping design or fabrication work.
