CHERNE Monitor WellŪ Plugs

Tamper-resistant design keeps your well safe and secure.

Designed to seal the groundwater monitor wells placed around underground storage tanks or around surface tanks, landfills or treatment plants.

Sized to seal schedule 40 and 80 piping. The 2" and 4" sizes can also seal schedule 5 plastic and stainless steel pipe. Made with chemical- and petroleum-resistant Estaloc™ plastic top and bottom plates and Nitrite/Buna-N sealing O-ring. Plugs come complete with stainless steel carriage bolt and yellow chromate-coated locking latch. Latches secure like a wing nut, the sealing O-ring expands to take up extra space. Once tight in the well, the latch is lowered onto the top plate. Latch is designed to use a No. 2 MasterŪ padlock.
