Locking Well Plugs

When you want to secure your well water, a locking well plug is the right fit. Our well plugs offer a watertight seal that is tamper-free, which can be placed at the top of your monitoring or observation well. The benefit of a tight fit is that your well water will be protected from insects, chemicals, and other contaminants. Well plugs are designed to fit snug inside the diameter of your well pipe. By turning the wing nut the gasket seal expands. This locks the plug-in place and seals the pipe of the well. Our products also have a locking mechanism that offers added protection to block access to the pipe. We have a wide range of styles and sizes of locking well plugs. Some come with extra features like vapor releases.
