The 4" H-Plug Locking Monitoring Well Plug SCH 40 is a cutting-edge solution for securing and monitoring well plugs. Made from hard-hitting Gallonass filled nylon, this plug is highly resistant to chemicals and extreme temperatures, ensuring long-lasting durability.

The H-Plug features a unique locking mechanism that provides an added layer of security. With the use of a specially designed wing-shaped key (sold separately), you can easily lock and unlock the plug, preventing unauthorized access to your monitoring well.

This nylon watertight expansion plug is similar to the Torquer but offers even greater reliability and performance. It is 100% nylon and completely inert, meaning it contains no corrosive parts that could potentially contaminate the well.

For your convenience, the H-Plug comes with a test well and warning label, ensuring proper installation and usage. To purchase the wing-shaped key, please note that it is sold separately.
