Mazco Safe-T-Stopper®
The Mazco Safe-T-Stopper® removes service tees in 10 - 15 minutes without gas release.

The Mazco Safe-T-Stopper® is a premium service tool designed to operate safely on natural gas service tee connections and other fluid connections of suitable configuration.
How Does It Work?
Mazco Safe-T-Stopper® is specifically designed to allow for open gut, pipe tees, street tees and no-blo service tee stopping or tee removal without hazardous release of natural gas.
Simply mount the tool over the tee, remove the cap on plug, set an expandable plug below the branch & remove the tool. It's that simple!
Service tee connections can be put back in service or removed without the hazardous release of the contained product. Safe-T-Stopper® can also be used to changeout faulty full port valves with no release of gas.
