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 Mazco tool over the tee, remove the cap or plug, set an expandable plug below the branch & remove the tool.

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 change out faulty full-port valves with no release of gas. Virtually any service line stopping or service tee upgrades are done safely and efficiently with the Mazco Safe-T-Stopper.

The Enhanced Base Tool will insert rubber plugs, self-tapping plugs, and perform all Safe-T-Stopper operations without requiring additional tooling with selected adapter packages.

By adding the applicable "Adapter Kit - Tee" to the 3000BV Base Tool, it can operate on Cap Tees, Plug Tees, Saddle Punch Tees, Mueller Tees, Elbow Service Tees, and Flapper Tees.
