Caplugs TPN-5 – TPN Series – Square Head Threaded Plugs with Flange, 60 Pack, High-Density Polyethylene (PE-HD), Black, to Plug NPT Thread Size 3/8-18", Oil & Heat Tolerant (ZTP5Q1)

Caplugs TPN Series Square-Head Threaded Plugs are made for NPT, or National Pipe Threads, meaning these threaded plugs meet national technical standards. Approved to protect the circumference of the port while simultaneously protecting the threads from damage and moisture, these plugs are commonly used for low-pressure testing and in-plant processing. These plugs are distinguished by their square head, an unusual trait for plugs, especially when working with threads and pipes. However, this design choice makes for an easy installation and therefore easy removal, as the square provides an easier point to push in than a regular plug, and the flange allows for simple removal, just grab onto to pull out. There are different sizes of square-head threaded plugs in the TPN Series to suit your various needs. This particular plug is made to plug an NPT thread size of 3/8-18". It has a total height of 0.67", the square-head has a width of 0.44". The high-density polyethylene (PE-HD) that these plugs are made from are not only strong to hold and protect NPT Threads, they can also withstand extreme temperatures ranges, hot or cold.
