REAL-TITE® PLUGS are designed with a stop on the bolt, to prevent the lower wedge from becoming dis-assembled from the unit and dropped down the line.

REAL-TITE® PLUGS have an extremely large gasket that seals behind, over and at the tip of the pipe or opening.

REAL-TITE® PLUGS are easy to remove and can be reused saving time and money.

REAL-TITE® PLUGS have a variety of uses including clean outs, test plugs, sealing iron or plastic damaged pipe with threaded or smooth openings.

Your Problem:

Find a leak proof solution for test plugs, or sewer cleanouts that are hard to reach and can become disassembled and potential of losing parts of the plug down the pipe.

Our Solution:

REAL-TITE® PLUGS have a stainless-steel stop bolt which prevents them from becoming disassembled and losing parts into the opening.
