What is a pipe plug?
Pipe plugs are threaded plugs that seal the ends of pipes to prevent the flow of fluids. They are used in industries ranging from domestic plumbing and construction to hydraulics, gas and oil transportation, agriculture, food and beverage manufacturing, and industrial chemical processing. Caps, however, push or thread over the outside of a part, while plugs push or thread inside the part. Caps and plugs prevent dirt, dust, moisture, liquids and any other contaminants from entering the opening during manufacturing, masking, storage and transportation.

Difference between caps and plug
Both pipe caps and pipe plugs belong to pipe fittings. At the same time, both pipe caps and pipe plugs prevent dirt, dust, moisture, liquids, and any other contaminants from entering the opening during manufacturing, masking, storage, and transportation.The basic difference between a pipe cap and a pipe plug is that the pipe cap is an internally threaded pipe fitting and is connected to the externally threaded pipe end, while the pipe plug is an externally threaded pipe fitting that is connected to the internally threaded pipe end
