12V Low Flow
The Flushlock Locking Well plug is designed to secure any round opening within the diameter of its expansion gasket. This dual rubber gasket creates an air and watertight seal preventing any contamination of your well between testing periods. With its domed top, you don't have to worry about water pooling on the lid either. The signature loopholes below the well seal are ideal for securing your bailers, pumps, or other sampling devices for easy retrieval. The Key Lock design prevents tampering by anyone without a key.
