Overview

This galvanized steel hex bushing facilitates a connection between 1/2 in. and 1/4 in. NPT piping. Each steel hex bushing uses larger 1/2 in. male NPT threads and smaller 1/4 in. female NPT threads to connect piping of varying sizes or act as a reducer in a fire sprinkler system.

When installed, this hex bushing can withstand temperatures of up to 450F (232C). This 1/2 in. x 1/4 in. hex head bushing has been finished with an electrodeposited zinc coating per ASTM B633 to resist corrosion.

Where can I use this hex head bushing?

In accordance with NFPA 13, this 1/2 in. threaded insert is compatible with any fire sprinkler system using 1/4 in. steel piping to:

  • Make a change in the size of piping
  • Reduce the size of openings of fittings when standard fittings of the required size are unavailable

This hex head bushing may also be used in non-fire plumbing applications, including hot-water applications with temperatures as high as 450F (232C).

This 1/2 in. x 1/4 in. hex head bushing also meets a wide variety of manufacturing and installation standards, including:

  • NFPA 13 (section 6.4.7)
  • B1.20.1
  • ASME B16.3
