End caps close off the end of a pipe run, sealing the line so it holds pressure and stays clean. They are essential for terminating branch lines, capping future expansion points, and pressure-testing a new installation before tools are connected.

Matching the cap to your pipe size and system standard ensures a secure, leak-free seal. Find the matching lengths and connectors in our air pipe and fittings selection, or explore modular aluminum air piping systems that make adding and capping drops simple.
