MONOFLEX® MM678XA4 62B-C034

Designed to provide a watertight, tamper-proof seal at the top of a monitoring or observation well. Simply slip the plug into the open-end of the well pipe. Then, as you turn the lockable brass wing bolt, the Buna-N seal expands against the inside of the pipe, holding the plug securely in place. To complete the installation and lock the well, slip a standard padlock through the matching holes in the stainless steel lock lever and brass wing bolt. Fits SCH 40 PVC or steel and SCH 5 or SCH 10 stainless steel pipe. An optional adapter ring is needed to fit 4 in stainless steel wells. These units do not fit SCH 80 pipes. The Blaze Orange glass-filled nylon top is easy-to-spot, sheds water and features molded-in TEST WELL-NO FILL warning.
