Locking Plugs

Our innovative 1" locking plug can turn a piezometer into a secure monitoring microwell. It is the only one able to mold and lock itself into damaged or bent schedule 40 or schedule 80 pipe. Made from 316 stainless steel and Buna N rubber, it fits both stainless steel and PVC (schedule 40 and schedule 80) risers, is extremely resistant to tampering, has a built in bailer hanger, and the parts are precision laser cut to exact specifications.
