In stock

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

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.
