Key Features

  • Square head cored plug for closing and terminating the end of a pipe
  • Male National Pipe Taper (NPT) threads for use with female threaded pipes

  • Meets standard ASTM B-584-06 for lead-free quality assurance

Product Description

The Merit Brass square head cored plug is a class 125 lead free brass pipe fitting with male National Pipe Taper (NPT) threads for closing the end of a pipe. The plug inserts into female pipes or fittings and connects with NPT threads, which create a tighter seal than straight threads, and it has a square head for increased leverage and use with a wrench during installation and disassembly. Lead-free brass is comparable in strength to stainless steel and is more corrosion resistant. This class 125 fitting meets standards ASTM B-584-06 (C89833), ANSI B 1.20.1, and ANSI B 16.15 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).

Merit Brass manufactures pipe nipples following ISO 9001 standards for quality assurance. The company, family-owned since 1937 and headquartered in Cleveland, OH, distributes pipe fittings in the United States and Canada.
