What Is an SP114 Threaded Square Head Solid Plug?
A 304 stainless steel SP114 threaded square head solid plug is a male-threaded fitting used to close a compatible female-threaded piping opening. Unlike a cap that fits over a male-threaded end, a plug threads directly into a female connection.
The external square head provides flat wrenching surfaces that help with tightening and removal. The solid-body configuration closes the opening without providing a through passage.
