Round Sealing Caps

Round Sealing Caps offer a simple and easy to use method to provide a secure and watertight seal for the top of surveillance or observation wells and prevent any unauthorized access.

They can be inserted into the top of any cut pipe, eliminating the need for adapters.

With the locking tool (5 or 6 point) the O-ring expands to make the seal on the inside of the tube. No additional padlocks are required.
