The plain plug is a kind of closed pipe fitting, which is used at the end of the pipe. There will be a square part at the head, which is convenient for installation or maintenance with a wrench. Unlike caps, a plain plug is an external thread structure, while caps are an internal thread structure.

The unique design of the plain plug, installed at the end of the pipe, can naturally form a whole with the pipe because there is no edge, so it is more beautiful than caps. If the plain plug is galvanized or chrome-plated, the overall feeling will be better.
