Symbols for Pipe Fittings

Oct 28, 2026

A reference list of standardized symbols for pipe fittings and associated components. The content organizes common fitting types by configuration and connection style, including flanged screwed, bell and spigot, and welded soldered arrangements. It covers multiple categories such as bushings, caps, various cross types, elbows with different angles and radius, reducers (concentric and eccentric), several valve families, tees, and unions. Many entries include dimensional markings shown alongside the symbols.
