In stock

This range of Pipe Thread Plugs are a Threaded Protection Plug that is suitable for National Pipe Threads (NPT).

These Threaded Plugs protect NPT threads against contaminants and moisture. The square head design allows the user to install or remove the plug by hand - without any need for use of a wrench or other assembly tools.

These Protection Plugs are available in High-Density Polyethylene (HDPE) for everyday applications or in Nylon, which is recommended when abrasion or heat are an environmental factor.

  • Colors: Black, Blue, Natural and Red.
